problem with pasting bitmap into a clipboard Mariusz Popiolek23-Sep-02 9:57 Mariusz Popiolek 23-Sep-02 9:57  Hi I'm trying to paste bitmap from program resources into a clipboard: #ifdef UNIETSIOFFICE_EXPORTS #define UNIETSI_API __declspec(dllexport) #else #define UNIETSI_API __declspec(dllimport) #endif int UNIETSI_API WINAPI uniETSIOfficePasteIcon(int nIconId) { CBitmap Bitmap; Bitmap.LoadBitmap( nIconId ); OpenClipboard( 0 ); SetClipboardData( CF_BITMAP, Bitmap ); CloseClipboard(); } This function is in mfcdll(mfc is linked statically) and everything works perfect in Win2000 (in which I have made my dll) but when I have tried this in Win98 nothing appears in clipboard(dll works, my function executes, all functions used in this code seems to work - return code !=0 - but nothing appears in clipboard). I don't know what is wrong.

If so, try loading a bitmap instead and see what happens. If is the icon bit that is failing, you might want to use LoadImage instead.

My problem is that the web site that the Web Browser should show needs to be current and not taken from the history, temp file, or cashe. What I want to know is how to delete or prevent the history, temp internet files, and or cashe from displaying old material, instead it should get the data from the Web Server everytime(Plus be able to detect if it is offline or not). If anyone can put point me to the river which contains this information, or show me how it is done, I shall be very gratefull. Thanks in advance Shell Gurus and Friends for your advice and guidance!

If you don't, you'll need to use the web browser control API IHTMLMetaElement to update the current web page. More info on syntax here[^].

New to computer programming Brandinimo23-Sep-02 9:30 Brandinimo 23-Sep-02 9:30  Hi everyone, I was searching the net for some programming resources and I stumbled upon this site. I'm looking to eventually get a posistion in the game developing business, but firstly I need to gain experience in programming. I'm 19, and going to college next fall, and I was wondering if maybe you guys could help me out. What is the ideal degree to have for a job in the programming field? I'm very computer literate, but have no knowledge of programming. The most well known language to me, or atleast most heard of, is C++. Would it be wise to perhaps buy Visual C++ and start working with it on my own? It would seem advantageous to me, if I know a bit of computer programming even before I went to college for my degree. Lastly, are there different programs to write C++? Or is it just Microsoft that makes the product? Thanks, Brandon Re: New to computer programming Joaquín M López Muñoz23-Sep-02 9:41 Joaquín M López Muñoz 23-Sep-02 9:41  What is the ideal degree to have for a job in the programming field? Computer Science, I guess. At least in my country, electrical engineers do quite a bit of programming work, too. If you're good at programming, I don't think the degree you take will make any significative difference when it comes to finding a job in the game industry (but definitely having a degree is better than not having it). Would it be wise to perhaps buy Visual C++ and start working with it on my own? Very wise. Lastly, are there different programs to write C++? Well, for Windows platform, VC++ is almost the only actual choice. There are other products, but they don't receive as much attention as VC++ does, by far. Joaquín M López Muñoz Telefónica, Investigación y Desarrollo Re: New to computer programming SanShou23-Sep-02 9:52 SanShou 23-Sep-02 9:52  The standard in the gaming industry is still C++ at this point. There are several options to programming out there as far as languages and I have heard of some games programming done in every language that exists. I would recommend Computer Science, although Electrical Engineers are good as well. However I think in Electrical Engineering you may learn more fun stuff (I am an electrical Engineer) you lose some of the theory of programming that may give you an edge over other candiates if all you want to do is software. However you may want to look at a software engineer program if one is available as that would merge more of the two disciplines. In my honest opinion for what you hope to accomplish studying C++ would be your best choice. Getting used to the Microsoft Visual C++ will get you closet to most gaming environments that are out there, but once again it is not the only flavor of c++ on the market. Linux has gcc. There is borland c++. Each of these will allow you to learn the language and get you in to programming and give you experience. Another approach for entering the gaming industry and one that I have been exploring is to download the tools for modifying a current game. These modifications often have a script language which is very similiar to C/C++. These are good tools to let you see what is ahead of you, however they may be a little confusing to start with. Don't worry too much about that, but they are good demos. Lastly, coding or programming to me is a skill that translate well accross boundaries more readily than most. I have worked in Visual C++ for many years now, but after I was laid off and started my new job, I was forced to support Visual Basic code for a while. The reason I say this is that even studying visual basic will help you learn to code and understand object oriented programming. The syntax however will be different, but if you learn to understand outside the syntax and understand the concepts, any language will work for you.

Get the sdk and documentation. The programming language would be C/C++, but that's not very important. It's something you learn as you experiment with the technology you're interested in, in this case gaming. I hope you're a dedicated geek , computer science is not for career minded people. You have to love it to succeed in it. Most aspects of it can be very fustrating, only a passion can get you to where you want to be. Especially something like game programming. Re: New to computer programming James A Beggs23-Sep-02 10:20 James A Beggs 23-Sep-02 10:20  What? Computer Science Degrees aren't for the career-minded? And what inspires that comment?

It is usually more difficult than such people anticipate. Re: New to computer programming James A Beggs23-Sep-02 12:07 James A Beggs 23-Sep-02 12:07  Ah! Thats cool. I loved CS and programming myself. Can be technical, creative, really use your brain, and still make a decent living. Well, except in the current market. With all the dot.com collapses that Washington had in the last two years, the IT market really suffered. I haven't worked anything but short term contracts averaging 3 months each in the last two years because of it. And that with an average of a month or so between each contract. Ugh. James A Beggs Microsoft MSN Mobile Component Test Team Re: New to computer programming Todd Smith23-Sep-02 16:16 Todd Smith 23-Sep-02 16:16  Start making mods for games. A lot of mod developers get jobs because of their work. There are lots of C++ "compilers". A lot of games run on Macs, consoles, etc. and use compilers other than Microsoft. CodeWarrior and gcc are two examples. Computer Science or an Engineering degree are good for programming. If your highly self motivated you might find CS a bit slow or uninteresting. If that's the case then look into something Engineering related where you can get a good math backgroud. There are also some schools now that offer game development degrees such as DigiPen.

But then I consider a description on MSDN showing that even unmanaged DLL's (normal libs and COM libs) could be reside version independent on Windows XP using a XML manifest description. Now I'm looking for deeper instructions how to use that functionality, but I couldn't find any samples or tutorials on MSDN (only the Platform SDK docs). Hope anyone can help me by stating a good book, link to a tutorial or even some sample code. Best regards Andi Re: Side-By-Side assemblies in Win XP Stephane Rodriguez.23-Sep-02 9:04 Stephane Rodriguez. 23-Sep-02 9:04  Search .config in MSDN. Any app can be associated to a .config file with versioned assemblies.

Help a Sort-Of Newbie! :/ James A Beggs23-Sep-02 8:38 James A Beggs 23-Sep-02 8:38  I am a very junior level professional programmer, and I'm having a problem - and I feel rather foolish about it. Generally, I've really preferred C++, but I haven't worked with it in some time, and until recently, I used Borland C++ Builder 3.0, which is somewhat old now. I'm now using Visual Studio 7.0 .NET, and I'm having a couple of problems. The first is that I'm having a devil of a time with editing a list box. Did this all the time in VB, but VC++ doesn't seem to make it as easy. I've opened up the properties, but it isn't giving me any options for adding data - and the data property in the property list is greyed out. The other is, how does one add a button or other control to the primary window itself for VC++? With Borland C++ Builder, I could just paint it on. And I can paint them on for dialogue boxes in the resource area. However, I can't find accurate information in the help files. While I am still looking for them, I thought I'd see if anyone out there could help me out with this. (I should probably get my hands on the books; this is a tool at my workstation I'm using, sans instructions. I can program in C++ just fine, but I'll be darned if I can find some of these GUI creation controls in VS .NET). One last thing: I had found a so-called tutorial in the MFC/C++ section for editing a list box - but some of the screen shots the person had displayed dialogue that I cant seem to bring up. It looked more like my VB 5.0 interface, and such items are not coming up in my VS in the C++ environ.... Thanks!

It's way different from what you have tried before, because you have only been using RAD (Rapid Application Development) tools. In VC++ you have to do it all by code... Take a look at this one.[^] - Anders Money talks, but all mine ever says is "Goodbye!" Re: Help a Sort-Of Newbie! :/ James A Beggs23-Sep-02 12:00 James A Beggs 23-Sep-02 12:00  Thanks. I work at Microsoft here in Redmond, Wa, as a short term contractor, and they have a company library. So, I went down and got a few books. Annoying. For my home use, I may have to check out Borland's most recent C++ Builder. One of the versions of it does include .NET material as well. What is your favorite C++ compilers?

Well, I "grew up" on Borland C++, then picked up C++ Builder 3.0. I liked it, a lot. I haven't used it in awhile, and I am debating on what to get, Borland, VC, or something else. James A Beggs Microsoft MSN Mobile Component Test Team Memory Leaks in Microsoft Dlls SanShou23-Sep-02 7:59 SanShou 23-Sep-02 7:59  I have been looking at solving some "inconsistent" problems with my program which seemed to be memory related. Strings displayed in dialog boxes overwritten when there was no command to change them. In order to check that I did a build with Boundschecker. Although I am not sure how I fixed my own problems , after a few full rebuilds and initializing data in the pointer class I was using, my code seemed to solidfy. However bounds checker gave me a list of memory leaks within external dlls. (i.e. Dynamic memory overrun Copying 65535 bytes to a block allocated in DNSAPI.DLL!0000121A Starting offset: 0, destination size: 2 bytes HANDLE: 0x0016B5A8 allocating thread ID: 0x6DC, current thread ID: 0x6DC Location of Error DNSAPI.DLL!0000141D (unknown) (unknown) DNSAPI.DLL!000015BA (unknown) (unknown) DNSAPI.DLL!00002AAF (unknown) (unknown) DNSAPI.DLL!000029E4 (unknown) (unknown) DNSAPI.DLL!0000298F (unknown) (unknown) Point of Allocation DNSAPI.DLL!0000121A (unknown) (unknown) DNSAPI.DLL!00002AAF (unknown) (unknown) DNSAPI.DLL!000029E4 (unknown) (unknown) DNSAPI.DLL!0000298F (unknown) (unknown) or Memory leak 1152 bytes allocated by MSVCRT.DLL!0000101F in MSVCRT.DLL!00003517, HANDLE: 0x01F31F20 Location of Error MSVCRT.DLL!00003517 (unknown) (unknown) MSVCRT.DLL!00001431 (unknown) (unknown) Is there a way to debug this.. I assume it is something that I am doing in the calling of the API and MFC code. Okay I am one that doesn't want to just blame Microsoft and release something with errors that I can resolve. Unfortunatly I am not a debug guru and haven't been able to study under any master, so any help could be cool. Otherwise when I get time, I guess I could comment out calls and find out what is causing these leaks. Trust me I learned alot debugging my AddRef/ Release extremly simple garbage collection for some classes. I learned I should probably have used a better smart pointer class instead of my simple technique.... Anyway thanks for any tips... The path to mastery is full of stupid moments and errors, but the error of the stupid is to assume that they are masters. Re: Memory Leaks in Microsoft Dlls Stephane Rodriguez.23-Sep-02 9:02 Stephane Rodriguez. 23-Sep-02 9:02  - you cannot debug MSVCRT - BoundsChecker is not always accurate. Far from that, type casting makes it easily confused and say wrong things about it. Moreover, you are not telling us whether BoundsChecker reports it is a object leak, interface leak, gdi leak.... If that's an object leak, then MSDEV is likely to show it as well (as a proof whether BoundsChecker is wrong or not). - Best advice would be : -- do not use DNSAPI if you can -- try to use it in another similar program MS quote (http://www.microsoft.com/ddk) : As of September 30, 2002, the Microsoft® Windows® 2000 DDK, the Microsoft Windows 98 DDK, and the Microsoft Windows NT® 4.0 DDK will no longer be available for purchase or download on this site.
