The font of the title bar of a Window is a system-wide setting and cannot be altered for one particular window. You can see the current font setting for title bars in the Advanced Appearance option of the display settings in the control panel. In fact there are separate settings for the active title bar and the inactive title bar.
If you want a particular window to have a different look for its title bar, you will need to create a dialog box without a title bar, draw the title bar yourself and then return HTCAPTION from the WM_NCHITTEST message handler when the user clicks on the drawn title bar.

I'm recording audio and I don't want to record silence. How can I do that? I'm recording using wimmm.
Is there a command or something like that?
Thank you
|

I dont know wimmm, but essentially silence are sample-values in a wave-file that aprox. 0 (there could be some noise). With that knowlegde you could create a program that modifies the wavefile... The Wavefile format is VERY easy, it's just a header followed by samplespoints...

hi all,
i have a service application, which maintains a record of each and every USB being used in the windows system.
in brief, my problem is with the hashmap values getting corrupted in between two threads. one thread picks the database path where values are to be written and other thread writes into that database path.
Service crashes at the, when the below codes are executed.
WaitForSingleObject(*hThreadIterBegin->second,INFINITE);
rename(hThreadIterBegin->first->c_str(),newFileName.c_str());
ReleaseMutex(*hThreadIterBegin->second);
The first thread fetches the values and the values are sent to the second thread so that it can write the necessary things to the fetched value which is the path of the database. but the hashmap value crashes at some point due to which the service crahses at above code executions.
i am not able to identify the exact reason, as to why the value of ThreadMutexMapPrimary changes or crashes when it is called from the second thread???
i am attaching the code below, with declarations and values i received while debugging.
Thankyou.

Your problem seems to possibly be related to an issue we saw in our own software. Switching to an alternate STL provider fixed our issues. See
http://support.microsoft.com/kb/813810[^]
You may well be being affected by this. BTW we switched to STLport a free STL implementation.
If you vote me down, my score will only get lower

HRESULT GetComponents([in, out] SAFEARRAY(VARIANT) oAxisComponentsArray);
I want to know how to realize the COM in C++ with InvokeHelper.
Thanks

In the IDL file it should be [in, out] SAFEARRAY(VARIANT)* oAxisComponentsArray
In the .h and .cpp files it should be SAFEARRAY** oAxisComponentsArray

Superman,thanks a lot.
Could you please tell me how to realize the SAFEARRAY(VARIANT) oAxisComponentsArray with C++, and how to write InvokeHelper?

Hi,
I am facing a problem with IWshRuntimeLibrary::IFileSystem. It is working fine on Win2003,Vista 32 bit. But fails in Win2008 std sp2.
I am using following function from IWshRuntimeLibrary::IFileSystem
1.CopyFile
2.GetFolder
3.FileExists
4.DeleteFolder
5.CreateFolder
I am currently using VC++.
Why IWshRuntimeLibray::IFileSystem is failing. Can I have any alternate solution.
|
|
|
|
|
Please debug and check the reason for failure
but i have the alternate solution as to suggest you to use SDK APIs
CopyFile :: Copies an existing file to a new file.
CopyFileEx :: Copies an existing file to a new file.
CreateDirectory :: Creates a new directory.
CreateDirectoryEx :: Creates a new directory with the attributes of a specified template directory.
CreateFile :: Creates or opens a file object.
DeleteFile :: Deletes an existing file.

This may not be an answer to your question, but the easiest way to do this is to place a picture control with a bitmap of the text with the required font size over the group box.

You mean some text inside the groupbox or the caption of the groupbox? If the caption of the group box, you could rename the ID of the group box such that it is NOT IDC_STATIC and then add a control variable to it (say m_GroupBox) and then call m_GroupBox.SetFont();

I m already try this but its not done.

OK, try this code:
CFont f1;
LOGFONT lf1;
::ZeroMemory(&lf1, sizeof(lf1));
lf1.lfHeight = 16;
lf1.lfCharSet = ANSI_CHARSET;
lf1.lfWeight = FW_BOLD;
::lstrcpy(lf1.lfFaceName, "Arial");
f1.CreateFontIndirect(&lf1);
GetDlgItem(IDC_GROUPBOX)->SetFont(&f1);
f1.Detach();
Obviously you'll have to change some things to make it work with your code but you'll get the idea.
Edit:
Actually, you might want to clarify first what Rajesh asked:

Hi all,
In my program, I have the following statement:
ISearchResultPtr spIsr = spWuSearcher->Search(criteria);
Most of time, the program will excute successfully, but when "criteria" is _T("UpdateID='12345678-9abc-def0-1234-56789abcdef0'"), then spIsr->Updates->Count is 0, but not 1 which is the right value.
Is there anyone who knows why or when this happens?
NOTE: I'm sure the "UpdateID" is right.
Any reply is appreciated.
Thanks a lot
