hi I''m trying to use the "GetOpenFileName()" function in my program when I compile I get to errors, but when I run my program and I click the "Load" button nothing happens, can someone pls help me with this function I tried to fill in as much members of the structure as possible

void LoadMap() 
{
	OPENFILENAME	lpofn ;
	
	lpofn.lStructSize = sizeof(lpofn) ;
	lpofn.hwndOwner = hwnd ;
	lpofn.hInstance = hInstance ;
	lpofn.Flags = OFN_ENABLESIZING | OFN_EXTENSIONDIFFERENT | OFN_NOCHANGEDIR |
					OFN_NONETWORKBUTTON | OFN_OVERWRITEPROMPT ;
	lpofn.lpstrFilter = "map-files", "*.map" ;
	lpofn.lpstrFile = "./levels/level.map" ;
	lpofn.lpstrTitle = NULL ;
	lpofn.nFileOffset = 9 ;
	lpofn.lpstrDefExt = "map" ;
	lpofn.nFileExtension = 15 ;
	lpofn.lpstrInitialDir = "./levels/" ;

	GetOpenFileName(&lpofn) ; 

} // end of LoadMap()
 

thanx in advance for any help

Is the BN_CLICKED message (via WM_COMMAND) being responded to by the invocation of LoadMap?

Thanks to Kylotan for the idea!

you mean if if windows knows I clicked the mouse?

because my program knows that I clicked because I use a code that changes my color of my button

wel here''s my mouse code :

void ProcessMouseInEditor(){	DIMOUSESTATE dims;		lpDIMouse->GetDeviceState(sizeof(DIMOUSESTATE), &dims) ;		GetCursorPos(&lpArrowPos) ;		// now check if the Left mouse button is pressed	if (dims.rgbButtons[0])	{		// if the cursor is within the Button "Load" :		if (lpArrowPos.x > 688 && lpArrowPos.y > 512 && 				lpArrowPos.x < 768 && lpArrowPos.y < 544)		{			SetRect(&src, 80, 16, 160, 48) ; // SetRect( &src, left, top, right, bottom ) 			SetRect(&dest, 688, 512, 768, 544) ; // SetRect( &src, left, top, right, bottom )			lpDDSBack->Blt(&dest, lpDDSGlobalBuffer, &src, DDBLT_WAIT | DDBLT_KEYSRC, NULL) ;						LoadMap() ;		} // end of if....... 

any1 pls?

this code works for me... your filter and filename ptr look a bit weird, but i''m not sure... try to modify my code for your own needs, and it should work...

you might want to do some error checking, to make sure the user selects a filename. if they dont, im assuming it might crash your program:




that makes sure nothing happens if they dont select a file

thanx alot!!!!!

k first of all thanx alot for the help again

second : strange things happen though
when I open the "open file..." dialog box and then press X or Cancel my mouse doesn''t work anymore (or it does strange things because when I go over another button it gets pressed without clicking on it)

and yes I use that last code, to check whetever there is a file selected or not
