The majority of the articles on CodeProject for sockets programming use the Win32 Sockets functions rather than hte MFC CSocket & CAsyncSocket, its only the user-interface that is built in MFC usually. So you can grab most of the socks code and build your win32 app around what you can pick up.

Is it possible to rename a project in VC .NET?

In the properties of the control, set the background color to:

-2147483633

(it'll change it to hex for you)

or you can do it via code:

CLabelControl* l = &this->m_yourLabel;
l->SetBackColor((long)GetSysColor(COLOR_3DFACE));

Attaching multiple controls to the system image list

Hi,

I am working on a program in which multiple controls use the system image list. My code looks like this:

<br />
	SHFILEINFO sfi;<br />
	HIMAGELIST hSystemImageList = (HIMAGELIST) SHGetFileInfo("a.txt", 0, &sfi, sizeof(SHFILEINFO),<br />
                                                          SHGFI_SYSICONINDEX | SHGFI_SMALLICON);<br />
	// this attach is ok, no errors<br />
	m_control1.Attach(hSystemImageList);<br />
	// this attach is not ok, program crashes, debugging shows this statement<br />
	m_control2.Attach(hSystemImageList);<br />

Attaching the first control to the system image list works ok. Attaching the second control results in a crash. Debugging points to the system image list attach.

Does anyone know what the problem is and how to solve it?

Thanks,
Woody

'open with' using shell

Problem: I would like to implement the following in MFC: Open a file using a program (for example, open a text file using Excel). That is, the same functionality as right-click on a file, select 'open with' and select the program. The file type will not be associated with this program.

I have succeded using ShellExecuteEx, and starting the executable file with the text file as parameter, but the limitation is that I have to know the locatation of the program executable, which can vary.

Grateful for help

/Stefan

I tried Start->Run "excel.exe c:\mydoc.xls" and it worked fine, without adding at all the app path. So I am not sure you actually need the app path.

In case you need it (for fun), just look up the registry HKLM\Software\Microsoft\Windows\CurrentVersion\App Paths.

NewElement.Add(a);
NewElement.Add(b);
m_Array.Add(NewElement);

I would like to using the SetCooperativeLevel function in window mode

Example Fullscreen mode => DDSCL_EXCLUSIVE|DDSCL_FULLSCREEN
result => I can use the CreateSurface function(return of CreateSurface function DD_OK).
Example Window mode => DDSCL_NORMAL
result => I can't use the CreateSurface function(return of CreateSurface function DDERR_NOEXCLUSIVEMODE).

What I do?
Example Window mode => (what parameters?)

Re: SetCooperativeLevel

U must add DDSCL_EXCLUSIVE when DDERR_NOEXCLUSIVEMODE is returned, so i guess

DDSCL_NORMAL | DDSCL_EXCLUSIVE

This flag cannot be used with the DDSCL_ALLOWMODEX, DDSCL_EXCLUSIVE, or DDSCL_FULLSCREEN flags.

In Window mode, you don't call SetCooperativeLevel at all.

Papa, no need to dump MSDN here Big Grin | :-D

. I expect someone willing to do DirectX stuff to download the DirectX SDK (or platform SDK), where there are plenty of windowed samples.

Renaming the source code file names

HI..
Just a quick question:

If I used visual C++ wizard to build a project n workspace for example TESTING...

How do i go about changing the name TESTING to another name like TESTING2...
'cuz it seems like i can't simply change the filenames of the visual C++
like this..
Testing.dsw -> testing2.dsw
Testing.cpp -> testing2.cpp
etc..

Thanks in advance.

Re: Renaming the source code file names

DarrollWalsh30-Sep-02 22:02

The problem is that when you rename Testing.dsw, and the other files, the settings in testings.dsw do not change. You will have to rename the files then add them back to the workspace and remove the original names. Hope that answered your question.

30-Sep-02 22:05

Editing the DSW and DSP file and replacing the occurence of testing with testing2, then renaming testing.cpp to testing2.cpp is enough
but i guess there's a tool on CP that just does that, search a bit!

visual studio 6 & .net with tooltips

RobertC30-Sep-02 20:40

30-Sep-02 20:40

Hi all.

Does visual c++ support tooltips (does it provide built in support)? I am sure that it doesn't but maybe i have missed something?

I was told by someone that it does and that it is very easy to do. But I have a feeling that they are talking about visual basic.

Also, does .net have built in tooltip support?

In all the time I have been using VC++ 6 I have never noticed the support in MFC apps.

Confused | :confused:

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
