You mean that I should copy the Background to a buffer image(1) when i begin draw a line. and then copy the (1) and a drawing line to another image(2),and then copy (2) to the screen?
But it also result redraw all the client when mouse moveing, then it will flicker. i make a test about this.
I load an image when application intialized, and draw it direct to the screen when mouse moveing, but it's also flicker.8(
Is there any mistake of me? Is I must use the SetROP2? but unfortunly is that it can't works with gdi+ in the same time.(is that right?) What should i do?
i ma realfly

You should draw your screen to an image, without starting a paint call. Then start a paint call and immediately copy that image onto the screen graphics object. The point of the double buffer is that everything is drawn off screen and put to the screen in one action.

Can I get the posting data of IE browser before the browser send the data to server?
using VC!
|
|
|
|
|
Can I control the IE browser by using a COM?
is there a example?
thanks!

Yes, you can. Internet Explorer has a rich set of COM-interfaces, so you can do almost anything you want. You can get the documentation (samples included) by downloading the Internet Development SDK from Microsoft, or by browing it online using the MSDN Library (URL for both the SDK and the Library: http://msdn.microsoft.com).

hi,
If u r using VC++ for ur application, i think its better to use the "Install Shield for VC++". That will save ur lot of work as we can do it easily with the wizrds taht it provides.
Hope this Hepls u...

May be i must for each toolbar button create item menu?
|

In VC++ 6.0 you could use the class wizard.
I guess in VC++ 7.0 it must be through similar means...

If your OS is windows xp,use this tool search
your hard disk for icons : Icon Searcher v1.3

This is driving me crazy  , wonder if anyone can help.
I'm am having some serious problems with GetMenuItemInfo and
SetItemInfo using WTL, but only with the dwItemData memeber, everything else seems to work
fine...
Let's say in OnCreate I try to add some data to the ID_FILE_NEW Menu
Item like so: lets make it a simple DWORD instead of a pointer just to keep things
clear...
CMenuItemInfo mii;
CMenuHandle menu = m_CmdBar.GetMenu();
CMenuHandle submenu = menu.GetSubMenu(0);
mii.fMask = MIIM_DATA | MIIM_ID;
mii.dwItemData = 1001;
mii.wID = ID_FILE_NEW;
if( submenu.SetMenuItemInfo(ID_FILE_NEW,FALSE,&mii) == 0 )
{
// Little helper function
ShowLastError();
}
Then when I the user selects the menu item in OnFileNew, I do this:
CMenuItemInfo mii;
CMenuHandle menu = m_CmdBar.GetMenu();
CMenuHandle submenu = menu.GetSubMenu(0);
mii.fMask = MIIM_DATA;
// I could actually use wID here passed in but I want to test
// the the specific menu item at the moment
if( submenu.GetMenuItemInfo(ID_FILE_NEW,FALSE,&mii) == 0 )
{
// Little helper function
ShowLastError();
}
DWORD dwTestData = mii.dwItemData;
dwTestData is always '0' no matter what I try to set it to.. I can
retrieve the Menu item text and print it out so I know I'm dealing
with the right menu item... I don't know if I am going wrong with
setting the data or retrieving it... It is really driving me nuts,
I feel like I am missing something very obvious here.
Thanks,
Scott

SetMenuItemInfo
The SetMenuItemInfo function changes information about a menu item.
Remarks
The application must call the DrawMenuBar function whenever a menu changes, whether or not the menu is in a displayed window.
Not sure if that will make a diff or not.

I got a really good reponse on this from the WTL group on Yahoo... It seems that the command bar class is causing the problem... It uses the data item to store drawing information, so I can either use a plain menu or extend the command bar class and use something like a STL map to store my data.. thanks for the reponse..

Does anyone know how I can program in Microsoft Visual C++ 6.0 in 16-bit for DOS? Thanks

I am just curious why?
I think (not sure) that I saw a 16-bit SDK on MSDN.

I dont think VC++ 6.0 can output 16 bit executables.
You might want to try alternatives like Turbo C++ for DOS
Or try and get an older version of VC++ that also came with the 16 bit model. Maybe 1.5.

I want to work with the HotKey Control in dialog .
And i'm interesting in the follows feature :
- how to store entered values ?
- how to put them into dialog (how-to put into dialog combination "Alt+Control+ A", for example, - at least with the simple letter presentation i have not find solution - how ?) ?
Also i'm interesting : I need all the time to convert manually VK_F8, MOD_WIN, .. etc. values into the codes (for storage) and vice versa, or exist much more wise solution ?
thank you

How do you go about dealing with a situation when the "lpDialogTemplate" variable in the parent's DoModal (i.e. Dialog::DoModal()) is null, when you are trying creating and calling a dialog's DoModal?
According to the comments in the CDialog code, it means that it failed to load the dialog template resource. But how would this happen? under what circumstances would you get this?
|
|
|
|
|
I guess if you accidentally rename or corrupt the dialog resource this would happen.

Hi,
I have some code like this:
-----------------------------
void CMyClass::SetIconText(HWND desktopLV)
{
LVITEM lvItem;
::ZeroMemory(lvItem, sizeof(LVITEM));
lvItem.mask = LVIF_TEXT;
lvItem.iItem = 0;
lvItem.lvItem.pszText = "Tralala";
lvItem.cchTextMax = 16;
::SendMessage(desktopLV, LVM_SETITEMTEXT, (int)(WPARAM)0, (LPARAM)(LPLVITEM)&lvItem);
-----------------------------
So, for test purposes, I'm trying to change the text of the first icon on my desktop. (The HWND is okay, since I can use other messages like LVM_SETTEXTCOLOR, etc.).
The problem is, that when the code gets executed, the program crashes...but I can't see the reason, since I believe I did everything okay (obiously, I didn't... .
Any ideas?
Thanks in advance

That will never work because the desktop window belongs to another process. The string is in your app's process space, which Explorer cannot access. You cannot pass pointers between processes without using shared memory.
