after you use LoadImage to load the bitmap, use this code in your window procedure to draw it:

case WM_PAINT:
{
    hdc = BeginPaint(hWnd, &ps);
    RECT rt;
    GetClientRect(hWnd, &rt);
    HDC DC = CreateCompatibleDC(hdc);
    // hBitmap is the bitmap loaded with LoadImage
    HBITMAP oldBitmap = (HBITMAP)SelectObject(DC, hBitmap);
    BitBlt(hdc, 0, 0, rt.right, rt.bottom, DC, 0, 0, SRCCOPY);
    SelectObject(DC, oldBitmap);
    DeleteDC(DC);
    EndPaint(hWnd, &ps);
}

If I did that, I would be doing your homework for you. It should be very easy to figure out with the code I have given you. If you have any more specific questions, ask the in this forum, there are lots of people who will help you.

Is it use break???? Or.........

Thanks!!!!

Hi,

Is there a function to set a timer?? In my case, I want to keep track of the time that a thread is being suspended, so that it would be suspended forever.

Or, can you give me any suggestion to do that??

Thank you! OMG | :OMG:

You can use SetTimer and then in the handler do your custom time tracking.

Thank you so much for your reply..! Smile | :)

But, I still have problem with SetTimer(). I always got error messages like "function does not take 1 (or 2) parameters". Can you please give me an example of using SetTimer?? For example: what I can do if I want to count in 5 sec??

Thank you !

Re: timer..

Nish Nishant25-Mar-02 16:12

SetTimer(1000,5000,NULL);

1000 is the ID of this particular timer
5000 means 5 seconds
NULL means the WM_TIMER handler of the CWnd object gets called

Passing parameters to an HTML page

I have a C++ program that has some context information for an HTML page. How can I pass parameters to an HTML page?

Thanks,

Derek Waters25-Mar-02 14:48

I'm not entirely sure what you mean about context information and what HTML page you're talking about.

If you've got a HTML control and you're using Navigate() to open a page, you just need to append the CGI parameters to your target path. For example for the page:

http://www.myserver.com/scripts/hello.asp

you can just append parameters to set the variable 'Name' to 'Joe Blow' and 'Age' to 25 as follows:

http://www.myserver.com/scripts/hello.asp?Name=Joe+Blow&Age=25

You need to replace ' 's with '+'s. Also, technically, you need to replace any unprintable characters with escape sequences '%2F'. To find out more, search MSDN for CGI and ISAPI information.

Hope this helps.

Derek,

Thanks for that input. I have just started tinkering with ASP but I think that would require a server right?

Here is the scoop. I have a MFC C++ application that uses the WebBrowser2 interface. I am navigating to an HTML file that looks like this:

<xml id="data" src="CurrentStates.xml">
<xml id="format" src="TransformCurrentState.xsl">

CurrentState.innerHTML = data.transformNode(format.XMLDocument);

The "TransformCurrentState.xsl" needs to parse through the "CurrentStates.xml" which is a database of several dozen elements. The user can identify which element to be parsed but I don't have any way to tell the script which element is to be parsed.

Ideally there would be a way to tell this script something like: building=1 floor=1 room=1. Right now I am doing some pretty ugly stuff. I am generating a small xsl file that is included by the "TransformCurrentState.xsl". It works but it feels wrong so I know there must be a better way.

Any more thoughts?

Thanks,

Steve

That doesn't look to good.

Here is the file again:

.<xml id="data" src="d:/NOWTrak/database/system/CurrentProbeStates.xml">
.<xml id="format" src="TransformCurrentState.xsl">

.
. CurrentState.innerHTML = data.transformNode(format.XMLDocument);

Oooh, XML. Sorry, can't help you with that, I'm afraid. I know that if you were using ASP (VBScript here, I'm afraid), and you tried to open:

http://www.myserver.com/scripts/hello.asp?Name=Joe+Blow

and hello.asp contained:

<%
vstrName = Request.QueryString("Name")
%>

then vstrName would contain "Joe Blow". As for how you use that in your XML, I'm not sure.

Resource DLL

WilliamB25-Mar-02 13:27

25-Mar-02 13:27

I am converting a lot of old projects' resources into separate resource DLLs so that we can easily localize the resource dll to different languages. For MFC application, it is easy since I only have to call "AfxSetResourceHandle" at the program's initialization. But, for a traditional C windows program, it seems there is NO such easy thing. For each LoadString or LoadIcon... in the original c program, I need to manually put the resource dll's handle there. Is there any other better way to handle this. Thank you very much.

Mapping solution for C++

Member 9625-Mar-02 12:43

Member 96

25-Mar-02 12:43

Hello, can anyone recommend Mapping software that can be integrated into a C++ application.

I've looked at Microsoft Mappoint, which comes with an ActiveX control which in theory should work in Visual studio however they repeatedly mention "for use with Visual Basic 6.0". I've scoured the net for the past two hours and could not find any concrete information on mapping libraries / controls that can be embedded in Visual C++ applications.

Any info would be appreciated.

If you can use it in VB 6.0 you will have not problem using it in VC++. Just simply import the type library that is declared for the active X control, and you can use.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
