midiOutGetVolume() accepts a handle to an open MIDI device or a device ID. MIDI_MAPPER</code (which does not have the value 0, rather 0xffffffff) is neither - it is a flag passed to <code>midiOutOpen() or midiOutGetDevCaps(). This flag is not supported by midiOutGetVolume(). You'll have to open the MIDI mapper with midiOutOpen() first.

For this, you can use a CHtmlView instead of the standard CEditView, or use a CFormView (I think) and add one HTML controls available on Code Project to the view.

I have a dual monitor on my system and it is very convenient to have different windows on separate monitors. On the bottom of my screen I have Find Results 1 and Find Results 2 as separated tabs (I have a picture but can't figure out how to paste it here).
If I pin both of them, they appear one of top of the other.
When debugging a program in run mode, I also have separated groups of tabs. In the debug mode if I pin both of them, they appear left and right of one another and I can adjust them to be on separate monitors.
I would very much like to be able to do the same left-right ordering in edit mode, but I can't figure out what controls it. For Find Results 1 and 2 this is especially convenient to be able to arrange on separate monitors, but as is they are above and below one another, completely wasting the space on the second monitor.
Any suggestions would be greatly appreciated.

Hi
I am using Visual Studio 2005. I have developed my project in VC++ which is a dialog based MFC application.
Here on the Button Click event of one dialog i need to get the value inserted in one edit box. for that I have declared variable also and i use GetWindowTextA() functions for that and it throw assertions. Showsing NULL value in hWnd...
I don't know why this happens........any idea? The same code works fine in Visual Studio 6.0
My Code looks like this :
=========================
void CPswdWnd::OnBnClickedButton1()
{
// TODO: Add your control notification handler code here
char sCurPswd[512]="";
m_Pswd.GetWindowTextA(sCurPswd,strlen(sCurPswd)); //Here it give assertion
}
My Variables are declared by righ clicking the Editbox and then "Add Variables" and then i have made the variable as "Control".
Any idea?
Thankx in advance
Mahesh

void CPswdWnd::OnBnClickedButton1()
{
char sCurPswd[512]="";
m_Pswd.GetWindowText(sCurPswd,strlen(sCurPswd));
}
Without "A" at the end. The compiler decides then which one fits best.

Since the buffer the O.P. allocated is a char buffer, they need to be using it with the ANSI version of the function. If their app is a UNICODE build, GetWindowText(...) will resolve to GetWindowTextW(...), and will not accept the char buffer.
Identifiers like GetWindowText that are #defined to different functions (the A or W versions) depending on the build type should only be expected to work correctly under different build types when using TCHAR as the character type.

It is likely ASSERTing because the you are passing the return from strlen(...) as the length of the buffer. These are two different things.
You should be calling the function like: m_Pswd.GetWindowTextA(sCurPswd,512).
Peace!

Actually, the second parameter is the max number of characters to copy into the buffer. This is important, because it does not mean the size of the buffer. That is why using sizeof(...) as was also suggested would be incorrect in a UNICODE build.

Use sizeof(sCurPswd)*sizeof(TCHAR) instead of strlen(sCurPswd).

Sorry you bug you Sir, Couldn't we use lstrlen for same?

Sure you can use it, but it'll still return 0 just like strlen().

hi All,
I want to integrate crystal reports into my MFC app. I have already done this using an Access db as a data source. But what I really want to do is to use an XML file as a data source. How do i do this?
I tried to modify the connection string:
// Connection String
_bstr_t bstrAccessConnect ( L"DRIVER={Microsoft Access Driver (*.mdb)};"
L"DBQ=Database.MDB;"
L"DefaultDir=;"
L"UID=admin;PWD=;"
L"Mode=Read;");
but it didnt work. I have configured the ODBC dsn according to the CR XML v3.6 driver. It is correct because I can access the XML file as an ODBC dsn from the Crystal reports manually...So how do i do this in code???
PS: I hav Crystal Reports 8.5

Hi,
I have a service installed on Windows 2003 Server OS. I would like to disable the "restart service" button and menu option in the services applet.
Some services like "Event Log", RPC, etc have them disabled.
Thanks,

Hi Friends,
Please check the following code.
PROCESS_INFORMATION piProcInfo;
STARTUPINFO siStartInfo;
ZeroMemory( &piProcInfo, sizeof(PROCESS_INFORMATION) );
ZeroMemory( &siStartInfo, sizeof(STARTUPINFO) );
siStartInfo.cb = sizeof(STARTUPINFO);
bool bRet=CreateProcess("C:\\apps\\Microsoft Office\\OFFICE11\\WINWORD.EXE",
NULL,// command line
NULL, // process security attributes
NULL, // primary thread security attributes
TRUE, // handles are inherited
0, // creation flags
NULL, // use parent's environment
NULL, // use parent's current directory
&siStartInfo, // STARTUPINFO pointer
&piProcInfo); // receives PROCESS_INFORMATION
DWORD dw=GetLastError();
if(NULL != bRet)
{
if(WAIT_OBJECT_0==WaitForSingleObject(piProcInfo.hProcess,INFINITE))
{
MessageBox(NULL,"Finished","Error",MB_OK);
}
}
here...WaitforSingleObject does not wait for WinWord app to finish...it just quits....Any soln/Reason?

Still it's not working...!

Just a thought...
bool bRet;
"if(NULL != bRet)"
Is it OK to compare bool with NULL?
|
|
|
|

Good point to notice.
I didn't noticed that.

After I wrote my response, I tried it out.
It works the way you wrote it. Even tough sizeof(bool) == 1 and sizeof(NULL) == 4.
So your test isn't skipped (as I suspected).

Why are you checking for NULL when CreateProcess() returns a BOOL value? Change bool to BOOL and compare against TRUE/FALSE.
