I want to somehow make my "About" box able to automatically write out the version of my program so I don't have to update it each time I make a new version.

How can this be done?

Something else

HRSRC hVersionSrc = FindResource(NULL, (LPCSTR) VS_VERSION_INFO, RT_VERSION);
	HGLOBAL hVersion = LoadResource(NULL, hVersionSrc);
	void* pvVersion = LockResource (hVersion);
	VS_FIXEDFILEINFO * pFfi;
	UINT cbVerInfo;
	VerQueryValue(pvVersion,"\\", (void **) &pFfi, &cbVerInfo);

Is there any way I can create a a CIPAddressCtrl with a drop down history like a combo box? Or, a CComboBox control whose edit box acts like a CIPAddressCtrl?

Sending messages to another application

Hi!

I was implementing the On-screen keyboard application that comes with Windows. I have two queries regarding this:

1. I have made my app 'always on top', but the problem is setting focus to the application just below this one. I am aware that SetFocus is useless in this case. I want to find a way to this using GetNextWindow

2. Let's assume notepad is going to be receiving keystrokes via this on-screen keyboard app. Can anyone send me code to this. I have tried something like:

DWORD dwProcessID;
::GetWindowThreadProcessId(hForeground,&dwProcessID);

::PostThreadMessage(dwProcessID, WM_KEYDOWN, 65, 1);
::PostThreadMessage(dwProcessID,WM_CHAR, 65,1);
::PostThreadMessage(dwProcessID, WM_KEYUP, 65,1);

But this doesnt help.

Any help will be greatly appreciated.
Thanks for your time

Richard

Better to use FindWindow or FindWindowEx and SendMessage or PostMessage

Win32 WinSock tutorial anyone?

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

Woody Green30-Sep-02 22:44

30-Sep-02 22:44

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.

sometimes it helps to look at the IL generated code
