Hello guys,i need some help.

i want to print image(any format what you can) directly to printer without call printer dialog.
i have tried to print text and it was successfull.Here's the source code:

CDC dc;<br />
    AfxGetApp()->CreatePrinterDC(dc);<br />
<br />
    DOCINFO docInfo = {<br />
        sizeof (DOCINFO),           // size of this structure<br />
        "print",                    // name of job - appears in printer queue<br />
        NULL,                       // output file, null means send to printer<br />
        NULL,                       // data hint for printer driver<br />
        0                           // banding flag (we don't band)<br />
    };<br />
    dc.StartDoc(&docInfo);<br />
    dc.StartPage();<br />
  <br />
    dc.TextOut(50, 700, m_text);<br />
    dc.TextOut(50, 750, m_text2);<br />
	<br />
    dc.EndPage();<br />
    dc.EndDoc();

And the question is i want to print image between the text (can be before or after), but i don't know what function of CDC can be used to print image???

OK, thanks for the help..............

Using ShellExecute() to execute program -- how to return quickly

shultas7-Feb-05 14:18

Hey all,

I have a program that basically searches a folder for excel spreadsheets and puts them into a list control.

On clicking in the list control, it is using ShellExecute() (simply passing the name of the file, not the excel executable) to launch the Excel and have it load the file.

It opens the file without a problem, however what is happening is the method that this shellexecute code is in will not go to the next line of code until Excel loads up, and loads the file. This is causing me problems because it is not hi-lighting the list control right away. Since Excel takes it's time to load up, and load the file, this is usually 30 seconds later.

I did a simple "MessageBox("FINISHED LAUNCHING");" directly after the ShellExecute call, and sure enough, the message box does not pop up until 30 seconds or more later when the spreadsheet is fully loaded.

I am wondering if there is another way around this, to get my program to launch excel, and move on w/out caring what Excel is doing, whether it loaded or not, etc. If I don't have to, I would like to avoid having to use some other method of launching the file that would cause me to have to specify the folder and executable name of excel.

Any help would be appreciated.

<font color=#008000>
//now Code this way</font>

 void CWindowNameDlg::OnButton4() 
{

}

UINT ThreadProc(LPVOID lpParam)
{
	char *strFileName=(char *)lpParam;
	MessageBox(NULL,strFileName,"",MB_OK);
 <font color=#008000>    //execute your file from here</font>

       ShellExecute(...);

	return TRUE;

Opening HTA with WebBrowser control

7-Feb-05 13:40

I have an MDI application that I'm adding a web browing component to interact with a client's HTML. We want to have their pages opening and staying within our app. I have to open an HTA file which is currently opening the client's web page in a separate IE browser. Is there a way to force the HTA to launch inside my app or do I have to modify the HTA? I have tried going through different examples on MSDN, but am not having any luck with the OnNewWindow2() override.

Thanks,
KJ

String problem in HKLM\MS\Windows\CurrentVersion\Run

Hi,

I have a weird problem where if I set a value in HKLM\MS\Windows\CurrentVersion\Run in my code, my app won't be launched. But if I double click on MyApp key, select the value, do a cut-paste of the same string, reboot the computer then it will work!

HKLM\MS\Windows\CurrentVersion\Run

Key: MyApp,
Type: String,
Value: "C:\Program Files\MyApp\MyApp.exe" (quotes are included in the string since there's a space in there).

Here's my code:

<code>TCHAR szPath[MAX_PATH+1];
TCHAR szFullPath[MAX_PATH+1];

UTLGetAppPath( szPath, sizeof( szPath ) ); //returns the path
_tcscat( szPath, NTS_ISMGR_EXE ); //adds the executable

memset( szFullPath, 0, sizeof( szFullPath ) );

_tcscpy( szFullPath, "\"" );
_tcscat( szFullPath, szPath );
_tcscat( szFullPath, "\"\0" );

//Add to run
lRes = RegSetValueEx( hKey, NTS_REG_STARTUP_NAME, 0, REG_SZ, 
			(BYTE*)szFullPath, sizeof( szFullPath ) );</code>

What is wrong???

Thanks! Smile | :)

You do realize that the Run key is only processed at login, right? Programs don't get run right away when added to the key. (Sorry, silly question, but I had to ask to be sure you understand how the key works.)

I know!

This is how I've tested:

I use InnoSetup for my app and it creates the MyApp key when installing my app. I reboot, everything is fine, app is launched at startup.

Then, I let my code handle the key. First, it deletes the key with RegDeleteValue and then creates (or should I say sets it) it with RegSetValueEx (as shown above).

I then restart Windows and although the key is there (and apparently with the same value), the app won't be launched!

I thought the problem was that I didn't add a null character at the end of the string but it still doesn't work!

One thing I did notice is that when I set the key through the code, there's '...' at the end of the string! If I set the value manually, the '...' disapears!

I think I found the solution:

lRes = RegSetValueEx( hKey, NTS_REG_STARTUP_NAME, 0, REG_SZ, 
		(LPBYTE)szFullPath, /*sizeof( szFullPath )*/_tcslen( szFullPath ) );

Replaced sizeof() with _tcslen()...

Michael Dunn7-Feb-05 14:47

That's almost right, you need to pass the length of the string in bytes, including the final null. So it's:
sizeof(TCHAR) * (1+_tcslen(szFullPath))

Are you a UNICODE program?

I ask this because you are doing a lot of TCHAR and _tcscpy.
If you are, then be careful when passing sizeof() into functions.

Check the API, see if it wants the buffer size in bytes or characters. If characters, then you should use (sizeof(buf)/sizeof(TCHAR))

No it's not using UNICODE. It's in bytes, not characters, but I think I found the solution by replacing sizeof() with _tcslen(). Is this safe?

Having trouble sending this

I'm having trouble sending some data from my SQL database over a socket connection. When I send it, I only receive 4 bytes. I tried memcpying it to a BYTE array but that also only sent 4 bytes. Here is my code:

<br />
		CString mySelect;<br />
		mySelect.Format("SELECT EMG1_E911_MSG FROM EMG1 WHERE EMG1_DEST_ID = '%s'", thdID);<br />
		pCommand.CreateInstance(__uuidof(Command));<br />
		pCommand->ActiveConnection = m_pConnection;<br />
		pCommand->CommandText = _bstr_t(mySelect);<br />
		pRecordset.CreateInstance(__uuidof(Recordset));<br />
		pRecordset->CursorLocation = adUseClient;<br />
		pRecordset->Open((IDispatch*) pCommand, <br />
			vtMissing,<br />
			adOpenStatic,<br />
			adLockBatchOptimistic,<br />
			adCmdUnknown);<br />
		_variant_t E911_Msg;<br />
		while (!pRecordset->adoEOF)<br />
		{<br />
			E911_Msg = pRecordset->GetCollect("EMG1_E911_MSG");<br />
			if (E911_Msg.vt != VT_NULL)<br />
			{<br />
				m_sConnectSocket.Send((char*)_bstr_t(E911_Msg), sizeof(1500));<br />
			}<br />
			pRecordset->MoveNext();<br />
		}<br />

I'm not sure it I'm setting something up wrong here. Could someone provide some suggestions.
Thanks

sizeof(1500)?

that evaluates to 4

is that what you intended?

Gdipluseffects.h new functions in GDI+ 1.1.

Anne Jan Beeks7-Feb-05 11:05

Anne Jan Beeks

7-Feb-05 11:05

According the MSDN documentation there are some new advanced gdiplus functions in GDI+ 1.1. Functions like red eye correction:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gdicpp/GDIPlus/GDIPlusreference/classes/redeyecorrection.asp[^]

According the preliminary MSDN documentation the defintions are declared in gdipluseffects.h. However the documentation states: Note: This documentation is preliminary and is subject to change. I tried CodeProject, MSDN, Google and newsgroups. But the only hits I found were others searching for this header.
Has anyone seen these new headers (are they available in Studio 2005 beta?). And are these new functions implemented in the freely distributable gdiplus.dll? Or are these functions only implemented in the version of gdiplus.dll that ships with Office 2003?
Any help appreciated.
Regards Anne Jan

yes. that's how i always handle it. set a flag when the button is pressed, and flip it when the button is released.

well here is an another suggestion.....(but a longer one)

create a bool variable say "m_clickon"(and initialize it with the value=FALSE) and make it true when ever ur leftbotton os down by using the OnLButtonDown....
make sure u handle thiz variable when the OnlButtonup as well (to set it back to FALSE).....
so whenever u move ur mouse..
the movemove handle is called.....then just check the status of this variable to say wheter the leftbutton is clicked or not...

happy programmin.....

cheerz.....

Anyone know a decsent tut on how to use libaries as this would help me a lot.

Hi,
how do I find out how much free store (memory when you call new/delete) is available to my program? If that's not possible how can I tell how much RAM is installed on the machine?

Thanks.
