Hi again,
How about int, double or float to String?
I usually used String.Format function:
int d = 20;
float f = 120.56;
str.Format("%d, %f",d,f);
AfxMessageBox(str);
The same error appeared. "cannot convert"
Hoping for your comments.
Thank you.

Do you mean int , double or float to "CString".
If not so, pls try CString.
There are functions like itoa(), atoi() etc to convert from int to string, and vice versa. Doing google search with "int to CString" will display many solutions.
I am sorry, I saw your post now only.
If you still need help, please post a new message, so that all people can see your question.
Best Regards,
Suman

I always use it like that and it works
CString str = "";
double d = XXXX; //Any value
str.Format (_T("%lf"), d);
Greetings.

Hi everybody,
I've written a mfc application which uses dundas gauge controls (together with windows forms). Everything works fine in debug or release mode but when I try to install the software on a different machine (windows XP, freshly installed) the application don't even start. Actually the installation works fine but the software don't run. I've checked all dependencies with dependency walker and also included "DundasWinGauge.dll" in the setup project (VS2005 setup wizard). DotNet is installed on the target machine. If I exclude the dundas gauge control then the application also runs on the target machine.
Does anybody have an idea?
Best regards,
Frank.

By chance, do you need vcredist_x86.exe on the target machine?

I don't know. What is vcredist_x86.exe? It's my first mixed-mode setup project. Actually it's my first setup project at all.

hm, this unfortunatly doesn't solve the problem I've installed vcredist_x86.exe on the target machine but the error still occurs.

Ok, could it be a (ActiveX) control that needs to be registered?

I use TeeChart as ActiveX Control but this doesn't seem to make problems. It is the only ActiveX control which I use. When I build the setup project with the ActiveX control and without the gauge control (dll) everything works fine. The gauge control don't have any ActiveX component.

I don't know wether the problem is due to the manifest file. I have know experience with mixed-mode setup projects. I just added the exe file to the setup wizard and when I compile the setup project it recognizes the dependency to the dundaswingauge.dll which is then added to the setup project. When I exclude the dundas gauge control from the project. The application runs fine also on the target machine. The dundaswingauge.dll doesn't show up in the manifest file. Might this be the problem?
Best regards,
Frank.

I'm using the Win32 API on WindowsXP with Visual Studio 2005 to create an application with toolbars. I am using imagelists assigned to these toolbars to manage their state. Previously, I was just using normal image list (TB_SETIMAGELIST) and a hot image list (TB_SETHOTIMAGELIST). In that code, I could press a button, and disable it. It would show as grayed out and pressed.
Now, I have added using disabled image lists (TB_SETDISABLEDIMAGELIST) which look much better. I can disable a button and it shows it as grayed out using my disabled image. I can press a button and it looks fine with my normal image. But if I press the button, followed by disabling the button, instead of getting a pressed button with my gray image, I get a somewhat pressed button (there is a different background color but its not "sunken" in), and my normal image is showing in color.
Is it possible when using disabled image lists to have them pressed too?
Thanks,

You are using Bloodshed C++ in the version given?
Then you should be able to add libws2_32.a to the list of libraries to link.

Then you should either add the lib to the makefile or enter it into the link-lib-dialog of whatever IDE you are using.

That is exactly the part I'm confused about.
How would I go about linking the file using the command line g++?
|
|
|
|

You really call your g++ by command line?
Normally, you use a makefile for anything more complex than "Hello world".
The g++-command line switch for "linklib" is "-l", i think. but better look it up in the help/man-file, by calling "g++ -?".

It is "-l".
Now tell me if I'm doing it right:
g++ test.cpp -l libws2_32.a -o test
The above line causes the folowing error:
"Cannot find -llibws2_32"
The libws2_32.a file is in the same directory as the test.cpp

You really should read a decent tutorial about using a makefile!
E.g. http://www.cs.umd.edu/class/spring2002/cmsc214/Tutorial/makefile.html[^]
But running
g++ -c test.cpp<br />
g++ test.o -l libws2_32.a -o test.exe
should work.
Maybe -L adds a directory to seach for libraries? ..;. would be ok to add here.
Sorry, I can't help you more than google can. I am not a g++-specialist and have no g++ here.
