I just found out that it is also possible to create a new VC6 workspace and add all source files from the VC7 project. It works Smile | :)

A VC project is not only a set of files, it's a full makefile. You won't be able that easy to target a given set of files to produce for instance a DLL with shared MFC.

Overriding DC of WebBrowser

I want the WebBrowser control to draw on my provided window (Static Control) instead of its own window. The actual thing I want to do is to make the WebBrowser invisible and display its contents on my Window.

I have tried exchanging window handles b/w WebBrowser and my Static control but it crashes program. This thing doesnt crash for exchange b/w two static controls and i get to draw what one static is drawing on other one by such exchange. But i want webbroser to draw on my window.

Isnt there anyway tht we override Device Context of WebBrowser.

Anythought are appreciated. Confused | :confused:

The web browser is hosted by an ActiveX control site, like any ActiveX, which hides all the complexity of the underlying windows, hence dc and stuff like that. Very unlikely you get to do what you want.
You could ask for the web browser to print (draw to a print dc), while you have selected a fake virtual printer, which you actually control. IMHO, this requires a printer driver (.vxd or something like that), ... Lotsa work! Cool | :cool:

Hi.
I tried to use CWindow::Print like this by first making the browser window invisible.
So i had no browser shown and still I could get a copy of image on my DC like this.

<br />
m_webBrowser.Print(pMyDC,PRF_CLIENT);<br />

Thanks your idea saved me days.

lose the right context menu sometimes.

ns22-Sep-02 5:40

What would make the right context menu that I custom wrote sometimes not show up? It can be doing finec and then sometimes it decides to just not appear anymore. Can I do anything to prevent this?

CMenu menuPopup;

    if( rcTHBImage1.PtInRect(point))
    {



        menuPopup.LoadMenu(IDR_MENU1);

        CMenu *pSubMenu = menuPopup.GetSubMenu(0);

        CmdRouteMenu(pWnd,pSubMenu);



        pSubMenu->TrackPopupMenu(TPM_RIGHTALIGN, point.x, point.y,this,NULL);

    }

Thanks,
ns

Well, there are plenty of things that can cause the menu to not show up (the point is not in the rect, the menu couldn't be loaded, the submenu doesn't exist, etc).

When you encounter a situation like this where the expected doesn't happen, it's best to write the code snippet defensively (in fact it's a good idea to always write defensive code), using ASSERT and VERIFY to check that things are OK. Use TRACE to trace control flow. Here's what I mean:

if (rcTHBImage1.PtInRect(point)) {
   TRACE ("Point is in rect...\n");
   CMenu menuPopup;
   VERIFY (menuPopup.LoadMenu (IDR_MENU1));
   CMenu *pSubMenu = menuPopup.GetSubMenu(0);
   ASSERT (pSubMenu != NULL);

   CmdRouteMenu (pWnd,pSubMenu);
   TRACE ("About to display popup menu...\n");
   pSubMenu->TrackPopupMenu (TPM_RIGHTALIGN, point.x, point.y, this, NULL);
}

very slow changes

ns22-Sep-02 5:38

22-Sep-02 5:38

I am making changes to my database. Its very peculiar that sometimes the changes get made quickly (I have the table open so I can look at it and it changes on the fly fast. Other times, its the same field I'm changing, and the new d ata takes ages to appear. If I keep the table closed and reopen it to check on its new value, sometimes the changes havent been made and I have to give it more time before I open it to check. What makes it take this varying amount of time to do the same thing? Other database operations are very swift. All I am doing is:

KeyValueMap::iterator it = m_EditkeyValueMap.begin();

    for (; it != m_EditkeyValueMap.end(); it++)
    {

        CString key0 = (*it).first;
        CString value0 = (*it).second;

        if (value0=="") value0 = "_";

        key0.TrimLeft();
        key0.TrimRight();
        key0.Replace(' ', '_');

        char* key = new char[key0.GetLength()+1];

        char* value = new char[value0.GetLength()+1];

        strcpy(key,key0);

        strcpy(value, value0);

        m_pRecordset->Fields->Item[key]->Value = value;  ///the main operation

        delete[] key;

        delete[] value;
    }

        m_pRecordset->Update();

yes i did and tried OLE automation. But it didn't help me. Someone in Adobe Forum responsed my question of " why I can't call functions of Adobe Acrobat Classes? ", as Adobe Acrobat doesn't not support OLE yet.

But I found how to print pdf file using commandlines. Those command lines are:
Acrobat.exe /t filenameWithpath printername drivername portname
what this command line does is :
1) initiates Acroat
2) print a file
3) then terminates Acrobat

first 2 steps done perfectly but step 3) closing Acrobat never happened.
don't know why.

I was so happy when I found out this command because all steps are exacatly what I want. open, print, and close. But closing doesn't work with this command as it is stated in "Acrobat Developer FAQ Document".

Do you know how?

Thanks

load BITMAP in DirectX

It depends on what DirectX graphics module you are using.

Are you using Direct3D? Then, the interface ID3DX has several functions to load BMP, PNG, and JPG (but not GIF) as 3D textures. These textures can then be rendered in a 2D mode by using D3DXSprite. (If you do search engine requests on these terms, you could probably use the bulk of other people's code to try it out.)

If you're using DirectDraw, then you're on your own in terms of finding functions to decompress graphics files. I suggest looking into the FreeImage library. (Go to www.6ixsoft.com for more info.)

Sure. Just make sure to export your functions with _stdcall
This is the way how I did it

This is how your exported functions in the DLL look like:

extern "C" __declspec(dllexport) void _stdcall YourFunction()
{
	// TODO: insert your code here
}

To make importing from Delphi easier it is recommended to change the function declaration in your .def-file like this:

; yourdll.def

LIBRARY      "yourdll.dll"

EXPORTS
	YourFunction=_YourFunction@0

This way you can simply import your function on delphi side by importing the function "YourFunction"

Hi. I've been working on these examples even after I unfortunately lost, my CD with source code provided with Petzold's book "Programming Windows" (version about 98 and NT). But now I'm stuck, and I desperately need the source code, to compare it with mine.
So, does anyone know where can I download it (for this version of book, not for Windows 1.0 or Windows 95), or if can someone send me only the source code (without executables), or even only, source code for 21th chapter.
Thanks.
