I'm hoping someone ran into this problem and knows a workaround.
Situation: to support proper uninstall I want my menu to be temporary (at each connect I recreate the menu). Appearently, items added to the main menu don't follow the normal rules and dont get removed when Word is closed. Another attempt... calling Delete on CommandBarControl when disconnecting fails for some reason.

You see that little search box at the top of this screen (directly under the CodeProject logo)? Go there and type "Screen Capture" and click the go button. You will then get a whole list of articles covering the topic.

Carefull of getdesktopwindow
If called from a modal dialog there is a chance the desktop becomes disabled, which disables all of its descendants. ie, it disables every window in the system.

Hi There,
I am getting error "Memory could not be written" only in release mode and that too not on my machine.
I thought of using MAPinfo to get the line number/function call where application is crashing. Unfortunetly address shown in error message doesnt come close to addresses mentioned in my MAP file.
I am very very confused, not getting any way to find this crash.
My memory address in MAP file starts from "0x00400000" to "0x004002xxxx".
Error message shows " The instruction at "0x77fcaea0" referenced memory "some address", memory could not be written.
Can somebody please help me in this? I am completely bugged with this error.
I am not able to reproduce this error at my end.
thanx in advacne,
regards,
Kavita

I know it doesn't really help you, but the chances are you are giving a bad pointer to a function
in a DLL. (Ie. every single Win32 API function). What you need is the stack of functions, so you can
see the last function of yours to narrow things down.
I'm sure there is an article or two here which may be able to help, but thats outside my realm!

Hi,
I guess you might be using the COM library.
Because some time back i too had the same problem when i was using COM library.
So what you need to do just go through the proper usage of the COM library and uninitialize it at some other place.
Hopefully it should work

It could also be that you are using a pointer to a heap object, 'delete' was called on the pointer, and then this pointer variable was used again a few lines later in the code. The compiler would not catch this I don't believe, but may have given a warning in the compilation if the warning level was set high enough.
Another thing that could be the cause is uninitialized memory. Release mode does not initialize the variables I believe. So you may be using a pointer somewhere that refers to a bogus address.
You may already know this, but one thing you could do is to build it in release mode and run it on your machine, trying exactly what the user did, and see if it breaks for you also. If it does, then you know approximately where in the code it crashed and can look into the code to fix it. You have to run it in release mode, for the reason in the previous paragraph. In fact, for this same reason, one should always test in release mode before shipping.

Also, about the addresses, they will most likely not be the same as what is on your machine, because it is the memory address used by that machine. These addresses could even differ between different 'runs' of the program. It would depend on where the user's operating system put the program in memory for that particular execution. So using the memory addresses to find the error will not work in this case.
One more possibility, which you probably already know about, is that you could have written past the end of an allocated buffer.

I am trying to delete an unwanted class. I am using C++.NET and I am having difficulties (to say the least).
I have “physically” deleted the files from the folder where they are stored and I have also “physically” deleted the .obj file. I have then cleaned the sln.
When I try to build the sln I get a LINKER error for unresolved external.
Can anybody please tell me what else I should do to get rid of this class that is haunting me?
Thanks in advance

Remove the files (.cpp and .h) from the solutions browser tree. You should be ok after this.

How to debug the dll, one exe contains more that dll, now i am trying debug viewer by using outputDebugString function, but my application is fully Dialog based. While running debugviewer gives a message m_pMainWnd is set to NUll, and after that it goes to terminate. where i can change the m_pMainWnd variable, please tell me how to solve this problem. and how to debug the dlls.

A DLL is nothing without an EXE to hang it off. In VC++6, select the DLL project. Press f5 to "run" the DLL.
VC++ asks for an exe to use, so select an EXE that would use your dll. If you are making a shell extension,
pick explorer. If you already have a build exe, use that.
Then let things run, and VC++ will attach itself to the process for debugging as normal.
Iain.

An additional tip to open the debugger in extreme situations is to place
AfxDebugBreak( )or
_asm int3; in your dll code.

from what i get this is a question where more programmers need help, so again:
i'm a novice programmer on Visual studio.net c++ and i need to connect it to mysql 4.1.17, it can be done with myodbc, bytefx or oledb, or another one that results, to make the normal operations (insert, select, delete, update ).
please help fast, it's really importante, and a sample application would be great, send it to horus.cv@gmail.com, but the code and the explanation is also good.
thanks sigh: sigh:

Why don't you start doing the expected sample application your self. And post the problems over here as you come accross.
Btw pls check this [^] list of articles

Yes, It is very Simple
You Must Create Dialog Dynamically
i.e.
CMyDialog dlg = new CMyDialog();
.....
delete dlg;
You Can Pass Position Param to Dialog with Constructor
or By Another Func, Like CMyDialog::SetParams(....);

Guys, I don't know if that's the right place to post but am in deep trouble. I've been trying to use windows sockets for sometime on visual studio .NET, but for some wierd reason my code won't compile. The compiler is always giving a C2065 error(undeclared identifier), I believe the reason may be that visual studio has a wierd macro definition which is getting some header files not declaring the SOCKET identifier. Any Help would be greatly appreciated, so would any other guidline or direction to some other forum... Thanks guys

Not enough info What line causes the error? What is on that line (and the line before it)? Have you looked up C2065 in MSDN?
You will get better answers if you actually provide some information for us to use.
