How to get information from a screen into file?
|
|
|
|
|
Can you be a bit more specific? If you are simply wanting a snapshot of the screen saved to a BMP file, see here and here for ideas.

Hi ,
Can u pls help me out with code in VC++.
I am using DirectShow filters to compress the audio I capture from Microphone.
The filter flow is as follows WaveDest->Encoder filter(Using GSM 6.10)-> Sample Grabber.
With the Sample Grabber filter I have grabbed some samples and written them into a bts file. So now I have the GSM compressed audio file in my "buff.bts" file in the form of bitstream.
Now how do I get the original file I captured from the mike to be rendered through the speaker. i.e In order to decode this Bitstream do I have to use decode filter in the playback graph but I do not know how to get the GSM 6.10 decoder filter.
Pls help me with the code

It seems that some dependency dll is missing - check your dll with dependency walker and you'll see what are the dlls it need.
Probably it's some msvcrt or something like that.
Hope it helps

Hi there,
i hope that someone can help me with this.
My application is SDI.
I wroted a class derived from CListCtrl which is created with
LVS_OWNERDRAWFIXED style.
There is a strange behaviour when i click on a different subitem on the same
selected row. It seems that it takes 800 ms till DrawItem is called.
My class implements two methods:
void OnLButtonDown(...)
{
TRACE("Start OnLButtonDown...\n");
...
CListCtrl::OnLButtonDown(nFlags, point);
TRACE("End OnLButtonDown...\n");
}
void DrawItem(...)
{
TRACE("DrawItem...\n");
...
}
When i click at different rows i see in the debug window:
Start OnLButtonDown
DrawItem
DrawItem
..
..
End OnLButtonDown
Meaning, DrawItem is called before OnLButtonDown() finishes.
However, if i click on the same row again i see in the debug window:
Start OnLButtonDown
End OnLButtonDown
DrawItem
In that case, DrawItem is called 800 ms after OnLButtonDown finishes.
Any idea?

Its probably due to the difference between a selection change and no change.
When you click the item for the 1st time, the control sends a message to the windows owner using SendMessage(). This causes the message loop to pump and process all the messages in the queue (otherwise the thread would block) which causes any WM_DRAWITEMs in the queue to be processed. When clicking the item the second time, the selection changing messages are not sent, as there has been no selection change, so the queue is not pumped until it returns from the LButton handler.

It takes us all, there is no reason.
For every purpose under heaven,
To each a turn, to each a season.
A time to weep and a time to sigh,
A time to laugh and a time to cry,
A time to be born and a time to die.
Dust to dust and ashes to ashes,
And so I end my song.

Hi Roger,
thanks for your reply.
You explanation seems very reasonable.
How would you solve that delay?
I tried to force sending selection change by calling SetSelectionMark method in OnLButtonDown,but the delay stays still.
I even called Update method or RedrawItems but the result is the same.
What cause the sole WM_DRAWITEM event to be sent after LButton handler returns?
How to solve the delay?

I think you would need to call:
RedrawItems(index, index);
UpdateWindow();
To move up the WM_DRAWITEM calls.

And if it is a CFormView you need to create a new document, like this.
POSITION templatePos = GetFirstDocTemplatePosition();
while(templatePos != NULL)
{
CDocTemplate* pTemplate = GetNextDocTemplate(templatePos);
CString strDocName;
pTemplate->GetDocString(strDocName, CDocTemplate::docName);
if(strDocName == "Form you want to open")
pTemplate->OpenDocumentFile(NULL);
}

Sorry, if this seems like a stupid question, but I simple cannot figure out how to run macros in VS.Net 2003.
I have pasted some macro functions into the MyMacro module, but when I try to assign a key to the macro only the predefined macros in the Samples module appear in the listbox.
Any help is much appreciated.

I want to access database which is in MY SQL on Linux machine from my "C" prgram without creating DSN. For that i have used function SQLDriverConnect as follows.
#define MAXBUFLEN 255
SQLHENV hEnv = SQL_NULL_HENV;
SQLHDBC hDBC = SQL_NULL_HDBC;
SQLHSTMT hStmt = SQL_NULL_HSTMT;
SQLCHAR ConnStrIn[MAXBUFLEN] =
"DRIVER={MYSQL ODBC 3.51 driver};SERVER=192.168.1.60;"
"UID=mWD=m;DATABASE=ftp;";
SQLCHAR ConnStrOut[MAXBUFLEN];
SQLSMALLINT cbConnStrOut = 0;
RETCODE retcode; // Return code
retcode = SQLDriverConnect(hDBC,// Connection handle
NULL, // Window handle
ConnStrIn, // Input connect string
SQL_NTS, // Null-terminated string
ConnStrOut, // Address of output buffer
MAXBUFLEN, // Size of output buffer
&cbConnStrOut,// Address of output length
SQL_DRIVER_NOPROMPT);
It returns SQL_ERROR.
Can you please suggest me where i am going wrong. I think it is in the "ConnStrIn".
