I am having problems "refreshing" a picturebox in Windows 98. In winXP this doesn't seem to be a problem. Is anyone aware of this, or can offer a solution, or where to look in my code Big Grin | :-D

Here is a snippet of one of my functions to let you know how I am displaying in the picturebox. The picturebox has a baseball diamond, and I write little .bmps of the baserunners and then I use TextOut to display the runner's names, but The names get written on top of eachother, which only happens in Windows 98.

<br />
void CJoeBroadCastDlg::DrawBatter(CString str_PlayerName)<br />
{<br />
   CEdit* Picture;<br />
   Picture=(CEdit*)GetDlgItem(IDC_PICTUREBOX);<br />
   Picture->EnableWindow (true);<br />
   Picture->ShowWindow (SW_SHOW); <br />
   CDC * my_cdc = Picture->GetDC();<br />
    if (!my_cdc)<br />
    {<br />
         AfxMessageBox("Error:  Invalid CDC pointer!!!");<br />
         return;<br />
    }<br />
	//load the base.bmp<br />
	CBitmap oBitmap;<br />
	VERIFY(oBitmap.LoadBitmap(IDB_BASEBMP));<br />
<br />
	//load the field.bmp<br />
	CBitmap oField;<br />
	VERIFY(oField.LoadBitmap(IDB_FIELDBMP));<br />
	my_cdc->SetBkMode(TRANSPARENT);<br />
    my_cdc->SetTextColor(RGB(255,255,255));<br />
    my_cdc->SetBkColor(RGB(189,153,103));<br />
	my_cdc->DrawState(CPoint(127,210), CSize(0, 0),  &oBitmap, DST_BITMAP, NULL);<br />
	my_cdc->FillSolidRect(127, 227, 100, 16, RGB(189,153,103));<br />
	my_cdc->TextOut(127, 227, str_PlayerName);	<br />
}<br />

This is called to "refresh" this screen, basically draws on top of all other displayed items before next event/drawing happens. But it doesn't seem to be working in Win98 Confused | :confused:

If a .bmp baserunner is drawn, it too is not cleared.

<br />
	//Refresh the screen<br />
	CBitmap oField;<br />
	VERIFY(oField.LoadBitmap(IDB_FIELDBMP));<br />
	m_picturebox.SetBitmap(oField);<br />

Thanks

You are drawing all that to an edit control? I don't know if you need to use an edit for some specific reason, but I think it would be much easier to derive a class from CStatic and do your drawing in the OnPaint of the CStatic subclass. Then, when you want to redraw it, you simply call Invalidate().

Thanks for replying to my disparate plea for help. For some reason I didn't get my regular email notification, so I just saw your reply late last night and I have been doing testing off and on thru out the day, in my spare time.

When I was doing research on the subject I found this link:
http://www.experts-exchange.com/Programming/Programming_Languages/Cplusplus/Q_20403906.html[^]

My user clicks on the menu "Open Virtual Game Cast" which then opens a dialogbox(CDialog(CJoeBroadCastDlg) it must be a dialog box because the user must tell the program which simulation number they would like to watch, and the dialog has stop and cancel button etc. In this dlg is a picturebox which has the Baseball diamond and baserunners running around , plus I use text to speech engine so the user also hears playby play.
But take a look and the link and tell me what you think, if you wish Rose | [Rose]

. I know I could have used a better approach but I am short on time and need to implement a fix ASAP, because the goal is to release by baseball season.
Thanks again.

If it wouldn't be too much of a problem, could you send me the bitmaps you use? I'll write up an example program, showing the proper way to get this type of thing done. Then it should be pretty straightforward to integrate it into your code Smile | :)

I just figured it out!!! woo hoo. I needed to add RedrawWindow() , in XP it did it automaticlly, I think.

I didn't get the notification email, so I don't have your email address but I posted the .bmps and the class that handles this here http://joeswammi.com/downloads/RES.zip[^]. It is not the best code in the world, I am self taught and have been programming for speed since I need to get the basic features done by baseball season. I appreciate your help. I think I understand what your saying, but I would have to redesign my whole class, which I would lose at least a week or two and that's when the real baseball season starts. That's nice of you to offer, if's it's not that much trouble, I would like to see the correct way of doing it, I tried researching this before designing the class but I couldn't find the correct material, but don't spend too much time on it, if you don't want to. Thanks I better goto bed Sleepy | :zzz:

Joe, i followed ur "rant" into here

your really missing the whole "window" paradigm. i have never tried to do what you are doing since it is so non-standard.

typically you don't draw into a device context of a child window from a parent window.

the standard approach for your situation would be to derive a class from CWnd that represents your drawing canvas, let's call it CDiamond. The parent window can handle placement and sizing of the child window if you desire. then when CDiamond class receives a WM_PAINT message you do your drawing to the device context at that time.

hope this helps

um, not to overstate the obvious, but does RedrawWindow() not work?

Hi,

How do you retreive the path and filename of the running program?
It's so I can create self-extracting modules.

Thanks in advance.

DWORD GetModuleFileName(
  HMODULE hModule,    // handle to module
  LPTSTR lpFilename,  // path buffer
  DWORD nSize         // size of buffer
);

for the hModule, just pass the HISNTANCE of the program, usually a variable named hInst in WIN32 APIs or returned by AfxGetInstanceHandle() in MFC
