Well .. COLORREF can handle 16 million colors i dont think that there are names for each one of them...
What you could do is to have a small array or string resource that you can map to the default colors (white, black,green,yellow,blue....) you know ..the basic ones.

|

Check out this article: http://www.codeproject.com/bitmap/ccolor.asp?target=ccolor[^] I've used this class before and whenever I need a color I just look up its name in the header file for this class. The article also has a display chart of all the colors it has pre-defined. Best of all the class is COLORREF compatible.

Gd day,
i want to like for example when this titleId 10 i selected, i dont know whether the popularity is updated or not. So this ID 10 has it own usagecount then it compare with usagecount of other titleID. Then the popularity will increase or remain same.
For That i had create the button "update popularity but how the function will be like--?? really thanks

This TitleID , Popularity are a set of IDs from my microsoft access database
Each set of IDs has it own usagecount and popularity.
For example, if the usagecount for this titleID 50 is 5, the old value of the popularity will be increment by 5.
Perhap how should i do this function.... /?? thanks much appreciated. i think this is rephrase better
The IDs are from the microsoft access database is link through ADO.

I am sorry Ohaiyo but I am having a hard time understanding what you're asking. No offense but my best guess is that you have field (TitleID) in your database and you have two more fields UsageCount and Popularity, perhaps on a different table, I really don't know because you haven't provided that kind of information.
First you have to go to the recordset that has the titleID that you are looking for. Perhaps by setting a filter or running a search.
To search you use:
public void find(String criteria, int SkipRecords, int searchDirection)
To filter you use:
public void setFilter(Object filter)
There could be other alternatives as well.
Once you have a pointer to the recordset you can update its fields by using:
_variant_t vField;
vField.SetString( (LPCTSTR) strField );
m_pRs->Update( vField, _variant_t( (long)lSomeData ) );
I hope that helps.

I'm trying to use the method GetSelItems from CListBox and I get a user error on a system that has an older vs of conctrl32.dll on it. What is the best way to update this dll to get this method to work properly when I install it on systems with the older dll?
|
|
|
|
|
How about just copy the newer version with your program?
I guess usually the program first look at its current folder for the files
before it looks for the window's folder.
I am not sure. But you can have a simple try of it.
|
|
|
|
|
comctrl32.dll gets loaded with the OS and you are unable to just copy over it with a newer vs. Anyone know how to overwrite a loaded system dll?
|
|
|
|
|
I am not sure, but you can prompt the user for overwriting, then overwrite it (there are articles on CP about how one can overwrite files being used), and then ask the user to restart.

I added successfully 4 MFC projects in Property Sheet.
Thank you for kind help.
However, I faced another problem.
2 of 4 MFC projects have CFileDialog in them.
To open and save files from directory that I want,
my code have following lines.
CFileDialog fileDlg (TRUE, "exe", "*.exe",<br />
OFN_CREATEPROMPT | OFN_HIDEREADONLY, szFilters, this);<br />
<br />
if ( fileDlg.DoModal () == IDOK )<br />
{<br />
..............<br />
}
When I try to compile and run it, it doesn't work.
Property page was successfully opened, but click open or save button,
program stoped and any I had to kill the process.
Debug process shows if ( fileDlg.DoModal () == IDOK ) line has problem.
But, it was working as a independent project.
Please help me.
Can I have solve this problem?
Thanks in advance.

|

CString yop = "Executable (*.exe)|*.exe||";
CFileDialog FD(TRUE,NULL,NULL,OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,yop,NULL);
FD.DoModal();
m_Path=FD.GetPathName();
Check the two ||at the end of yop. these are the ones that screw up your CFileDialog.

Hello,
My project (MSVC++6, SP5) is under MFC and I use templete such as
CMap, CList, CArray, etc.
I also want to use a class that is written under STL, using such as string, vector, etc.
However, when I combine the class into my project, I find the compiler will get errors such as:

from google, I find one possible reasons at:
http://msdn.microsoft.com/archive/default.asp?url=/archive/en-us/dnarvc/html/msdn_stlfaq.asp
which it says things as:
vector<int, allocator<int="">> iV;
The problem is caused by the consecutive ">>" at the end of the declaration. The solution is to put a space between them, so the above becomes:
is causing the problem.
However, I don't see such thing in my program (at lease no such direct problem as above).
Does anyone know any other possible reasons and how to solve it?
Thanks a lot in advance.

I find out one additional information:
no matter where, if I include:
#include <iostream>
or
#include <string>
I will get the above errors. but if I include:
#include <vector>
it will be OK.
This is quite strange to me. (I don't know much inside the STL)
Hope someone has any idea of this.
Thanks.

Sorry, I find the above post does not display right.
See below.
I find out one additional information:
no matter where, if I include:
#include < string >
or
#include < iostream >
I will get the above errors. but if I include:
#include < vector >
it will be OK.
This is quite strange to me. (I don't know much inside the STL)
Why the string include will have problem while vector include is OK? Any difference to the compiler?
Hope someone has any idea of this.
Thanks.

Could you post a code sample, on how you combine the classes ?
~RaGE();
|
|
|
|

I find the class is not long, and
re-coded it into MFC without using STL.
It works now.
But thanks anyway.
(I personaly still think it is the function overload/ride
or namespace problem, especially for < and >, >>, << etc.)
Have a nice day to everyone!~

Hi,
I must add some report generation to our application. The reports should be customizable via templates. I thought about having some XML/XSL to generate HTML output and to display this output via a CHtmlView. The only problem I have (right now) is that I can't find a way to show the application generated images within the HTML page. Feeding the generated HTML source to the IE is possible via a technique used in the CHTMLWriter class (http://www.beginthread.com/Article/Ehsan/Adding%20HTML%20Content%20to%20the%20WebBrowser%20Control%20Dynamically/)
Showing static images is possible via the res:// protocol, but what about generated images. Is there a simple solution to add callbacks to the IE, so that I can provide the image during the rendering stage?
Writing the images to the disc is a solution, but not an elegant one.
Any ideas?
Thanks
Dirk

I think that might be supported as an mhtml document.
I'm not sure how far the support for such has yet
gotten.

MHTML, never heard of this...
searching the web, this could be the solution, but it seems, that Outlook Express is required.
Thanks for the idea.

Web Archive
When you save a Web page as "Web archive," the Web page saves this information in Multipurpose Internet Mail Extension HTML (MHTML) format with a .mht file extension. All relative links in the Web page are remapped and the embedded content is included in the .mht file, rather than being saved in a separate folder. The absolute references or hyperlinks on the Web page remain unchanged and the .mht file is viewed using Internet Explorer.
MHTML enables you to send and receive Web pages and other HTML documents using e-mail programs such as Microsoft Exchange, Microsoft Outlook, and Microsoft Outlook Express. MHTML enables you to embed images directly into the body of your e-mail messages rather than attaching them to the message.
NOTE: "Web archive" is available only if Outlook Express is installed. The ability to save a Web page as a Web archive file is provided by the Inetcomm.dll file (the Microsoft Internet Messaging API file), which is installed by Microsoft Outlook Express 5.

For a plain old C++ programmer like myself, what benefit would there be for me to upgrade to .NET?
Is the C++ compiler faster?
Is the debugger better?
Is it cooler?
I'd need to convince my boss.... what can you tell me.

NO. It is slower.

Yes.

Yes, but as I learned early not all of your code will compile without modifications.

For the few projects where I have timed the difference between VC6 and VC7, yes, a bit (maybe 5 - 10%)
And the programs it makes runs up to 25% faster 
Peter Weyzen wrote:

Well, there's some small things that have been fixed. Overall I really like it, and in day to day use it better than the VC6 debugger, I think.
Peter Weyzen wrote:

I love the new IDE, you have to give it a few days, or weeks, but then most people love it, although there's still people that hates it 
If you use ATL, ATL7 is way better than ATL3 from VC6. I use it a lot and love it

i hate the interface and can't stand to use the thinig unless i have to. i do all my development in VC6 and only build in VC7 for customers who need the VC7 versions of our libraries.
there are a few serious bugs in the IDE (those in dependencies checking and in the help system are the two that annoy me the most).
to an old time VC guy like me, the new interface seems like VB Gone Wild. but obviously, some people like the new interface. there does seem to be a lot of cool stuff in there, but i can't bring myself to break away from old faithful VC6.
i'm hoping the next version will fix the bugs, and that the upgrade will be cheap
