How can make my dialog windows get to the top of the right on my desktop?
|
|
|
|

Get the dimensions of the screen by calling GetWindowRect(), then call MoveWindow() on your dialog.

Additionally, get the desktop width via GetSystemMetrics(SM_CXSCREEN). Then, move your window to (0|screenwidth-appwidth).

I am new to VC++.
So i want to know how to write program in VC++ to read and write data from/to smart card.

yeah i too have worked with the smartcard but using com port not with api's yeah,if you havbe some sample with your sdk,send it to me i will help you to understand that ok.
actually the smartcard are harwdare dependent,some menufacture smartcard device work on different command set and other on different there are a few manufacture who actually following the ms smartcard api,is you reader manaufacturer is compliant with ms.
ok

When it runs on my computer is good but shapes(as ellipe, square, circle,...) are crooked when my application runs on other computer, I don't know why... Please help me...thanks.

Hello,
I am loading a dll from an app (.exe) and it has to remain in memory after the app terminates execution.
Well, the problem i've been having consists in that whenever the app stops running, the dll is automatically freed (possibly because it is associated with the creating thread/instance.)
How can I prevent this from happening? I mean, how can I make the Dll remain in memory until it receives a notification saying it can terminate?
Thanks,
Dave
BTW: it is a dll with MFC support...

And do what exactly ?
The dll is just a bunch of functions, the exe is the main thread of execution.
What are to trying to accomplish ?

What you're asking doesn't make sense. By definition, a DLL is a library - it is an extension to an application. It makes no sense to have a library in memory without an application using it.
Basically, you can't do this. Windows automatically frees all libraries when you close your application. There is nothing you can do about it, by design. If you want your DLL to stay in memory, your application has to stay in memory as well.

Hi,All,I am developing an ACTIVEX control embedded in IE, which is used to display continuous jpegs captured from a server.Firstly I wrote my ACTIVEX control in MFC,and call InvalidateControl() to realize control window redraw.It is ok.Then I rewrote my ACTIVEX in ATL,most of the code regards to grapic are same,but this time since InvalidateControl() can not be called in ATL based control, I call FireViewChange() to realize control window redraw time by time.However,I found that the control window got flicker when it is redraw.What happened and how to deal with?
please contact:

Hi
I have made one DCOM application which runs successfully but at the end it hangs out and doesn't gets closed in normal way...Any help or any idea...
All statements are getting executed very well in sequences...but at the end it is not returning as it should return at the point of call.
I used this small DCOM application in my VB application. At the point where I call this DCOM it runs well and does all the task that I want it to do. It's control also goes at the last line i.e "return S_OK" but then it hangs out.
Any one have any idea plz..my whole code is written here...

Im stumped beyond words.
There are several articles on how to programmatically set the
default printer. I just can't get any article to work. If I
make the printer settings dialog box popup and the user selects
a different printer, that works. But I haven't had any luck
programmatically changing that on my own.
Any ideas or any feedback any one can provide will be greatly
appreciated.

I wanted to draw a 256 color bitmap from a resource to a view window but i was wondering how i can do that ??????????????????
|
|
|
|
|
Have a look at this article.
http://www.codeguru.com/Cpp/G-M/bitmap/article.php/c1721/
|
|
|
|
|
i have already seen that article and used it in my code but the line
if( dc.GetDeviceCaps(RASTERCAPS) & RC_PALETTE && palette.m_hObject != NULL )
{
dc.SelectPalette( &palette, FALSE );
dc.RealizePalette();
}
the evaluation in the if statement is always NULL and nothing is drawn on the screen i am drawing in the CView::OnDraw() function and i created one class storing the bitmap and palette all together and some operations as loading image generating the palette and so on but nothing is drawn
|
|
|
|

CDC *dc = GetDC();
CDC memDC;
memDC.CreateCompatibleDC( dc );
CBitmap bitmap;
CPalette palette;
GetBitmapAndPalette( IDB_BITMAP, bitmap, palette );
memDC.SelectObject( &bitmap );
// Select and realize the palette
if( dc->GetDeviceCaps(RASTERCAPS) & RC_PALETTE && palette.m_hObject != NULL )
{
dc->SelectPalette( &palette, FALSE );
dc->RealizePalette();
}
dc->BitBlt(0, 0, 180, 180, &memDC, 0, 0,SRCCOPY);
This is working

How to define a specific dialog window dimensions when the application (dialog based) starts?
I could 't find such property in the property tabs.

Just started build test apps with VC++.Net and I have a few silly questions?
1. I need to write dynamic/data access web pages and I am not sure exactly what project type to use (so many!), I am currently building test apps in the 'Windows Forms Application .Net' project type, am I ok?
2. I would like to put a simple button on a web page (I have Dreamweaver etc) click it and my window pop up? not sure how I take the .exe file generated and actually get this to happen? think its something to do with XML and the XML file writing/reading classes?
3. Thanks a lot? I appreciate all help and value it!
Many thanks for your time and may the force be with you! (you'll need it!)

1. Use the PHP language. Search Google with "Data access with PHP". PHP scripts can be written directly into a HTML document, thus allowing access to a database directly.
2. The button click usually causes a script event. If you are using JavaScript, then here is a piece of code that starts a program on the machine:
function openNotepad() {<DIV>
var oShell = new ActiveXObject("Shell.Application");
var commandtoRun = "C:\\Program Files\\Microsoft Office\\Office\\WINPROJ.EXE";
var commandParms = "C:/Filename.mpp";<DIV>
oShell.ShellExecute(commandtoRun, commandParms, "", "open", "1")
}Just change the path to point to your executable and omit the parameters. See ShellExecute in JavaScript reference for more information. It might be that this will not work, as it is a security risk to allow scripts to execute applications (Think about executing "format c: /y"). An another alternative is to fire an open/save dialog.
If you only need to open a window/dialog, then you shouldn't use an executable at all. I think Dreamweaver has the tools to write a Flash component that acts like a window, showing buttons, getting results and so forth. Then just insert this component into the web page.
Hope these will help.. If not, then post more information on your problem, and consider if there are any alternatives available, mostly due to the insecurities in script-based command execution.

Hi!
I'm trying to write my own HTTP server in Win32API, with the Winsocks API.
For the moment, it can read the GET and HEAD methods, so I can handle basic HTML and JavaScripts which don't tell data to the server.
To to this, I would like to use the POST method, but I don't know how to use it.
It would be great if you could send me documentation about POST and other specifications about HTTP methos (with samples if possible)
Thanks !
