I'm learning about .NET and I followed my book on how to set things up for edit and continue. Under Project->Properties, debug info format should be Program database for edit and continue(/ZI), by default it is /Zi. Then "compile as managed" has /clr. But when I go to compile, I get that these two command line switches (/ZI and /clr)are incompatible. SO tried compiling as unmanaged but the project I am trying this idea on is actually one with __gc etc (its a sample using mscorlib.dll), so it really needs compiled as managed (as the compiler tells me gleefully when I compile as unmanaged). I dont know if this is enough information., but what do I need to do to get the edit and continue going?
Appreciate your help,
ns
Or is it that you cant edit and continue with managed code?

Well.. we are using the APCI Relay8/In8 Card from Arcom since years.. never had problems with it.
Now we would like to use the AIM104-Relay8/In8 Card.. and we are having problems finding a lib file for MVC++ 6.0. (All the given files are for Borland C versions).
We are not able to use the Borland libs and we are not able to make new Lib's from the sources. (Missing some functions and keywords)
Does anybody has got any solution for this?
Thanks in advance,
bernhard

Hello, please help me with my special problem:
First I have an MDI-Application. In this application I call an MFC-DLL function to calculate different operations...
Now I need to call (from within my dll) a TextOut-function from my application (class View). How can I solve this problem....
Please help me

Youe EXE calls a function within your DLL, and this DLL then needs to call a function within your EXE? Not a good idea. I suppose it's technically possible to export a function from an EXE, but I've never done it. Why not just have the DLL post a message to your EXE and let the EXE handle the UI?
|
|
|
|
|
Is it possible to post an String or an CRect with PostMessage / SendMessage?
|
|
|
|
|
As long as the object is allocated on the heap. In other words, you couldn't do something like:
void SomeDLLFunction( void )
{
CRect rect(1, 2, 3, 4);
::PostMessage(HwndOfEXE, MY_MESSAGE, 0, (LPARAM) &rect);
}
Because before the EXE has had a chance to process the message, the CRect object has gone out of scope. Instead, you would do something like:
void SomeDLLFunction( void )
{
CRect *rect;
rect = new CRect(1, 2, 3, 4);
::PostMessage(HwndOfEXE, MY_MESSAGE, 0, (LPARAM) rect);
}
Then in your EXE's message handler, it would use the CRect object, and then delete it.
BEGIN_MESSAGE_MAP(...)
ON_MESSAGE(MY_MESSAGE, OnMyMessage)
END_MESSAGE_MAP
LRESULT OnMyMessage(WPARAM, LPARAM lParam)
{
CRect *rect = (CRect *) lParam;
...
delete rect;
}

How can I get the HwndOfExe - Parameter?
|
|
|
|
|
Two ways, although they are practically the same. Create another exported function in your DLL that accepts as a parameter, the HWND of the EXE's window. The DLL will store that value for later use. Or, modify the other exported function in your DLL to accept an additional HWND parameter. Make sense?

just pass athe valid Device context of that view to the function in ur DLL and by using that u can display .
Like void DiaplayText(CDC*pDc, char* pszText)

I am looking for some ideas on a way to implement a copy file function w/o using WriteFile or CopyFile. I know this sounds tough. This is what I am wanting to do. WriteFile and CopyFile are fairly intensive on a network and I need to come up with a way to write a file (copy it) from one network drive to another and have it be fast, really fast. Unfortunately, I haven't been able to come up with a way for this to happen. Any thoughts?
|
|
|
|
|
ever tried SHFileOperation ?
i don't think that it is faster than CopyFile.. but maybe you should give it a try..

Whatever you do, you'll still have to physically transfer the file across the network and there's no way around that - it will be just as network intensive using CopyFile/WriteFile as it would using some other method. Possibly the only thing you could do is compress the file before it is transferred, but if its big enough for you to worry about the network then its going to take some time to compress and decompress it (and that presumes its something that can be compressed).

You can use the function SHFileOperation. With this you can move, copy, rename or delete files and folders. It handles most of the checks like a file or directory with the same name existing at the destination etc.

Hi,
Actually I'm a PowerBuilder developer but I'm trying to do some C++ programming also. Because of the rather poor UI PowerBuilder offers (especially for menus), I like to make an ActiveX control that creates a menu based on settings the developer can enter and, at runtime, set that menu as the menu for the powerbuilder application. By ownerdrawing the menu I wish to make an OfficeXp like menu.
I have no idea how I can do this. I know how to create an ActiveX control I can use within my PowerBuilder application but not how to make an ActiveX that creates something in the background and shows it within my application.
I hope some of you can give some hints and/or tips how to accomplish this.
Regards,
Aart Onkenhout

Hi,
My application logs data during an experiment. I need to prevent silly users from shutting the application half way through an experiment.
So, how can I disable the 'exit' button and menu option?
How can I intercept the exit command so that I can ask the user if they wish to save any 'unsaved' data?
Thanks for any suggestions,
Ali

Check the docs for the WM_CLOSE notification message.

i think it is better to put a flag for it, for enable the flag when u start the process , and disable the flag when ur opertaions completed.
and you will get all the message to the window if you override
PostQuitMessage().you just check the status of the flag there and decide whcih operation you want to do.
Hope that you got the idea...

Yeah, I think I understand. I'll give it a go.
Thanks,

If you doing this in MFC, override the documents SaveModified() function. As long as you set the modified flag to true during the experiment, you can return FALSE to stop the document and the application closing.

Another option is to override BOOL CDocument::CanCloseFrame(CFrameWnd* pFrameArg)
and do whatever you need to do to check/verify that it is ok to close the frame.

How to change Dialog background color in dialog based applications.

Handle WM_ERASEBKGND yourself. In MFC parlance:
BOOL CSomeDialog::OnEraseBkgnd(CDC* pDC)
{
CRect rect;
GetClientRect(rect);
// yellow !
CBrush brush(RGB(255,255,0));
pDC->FillRect(rect,&brush);
// tell the framework we handled this
return TRUE; // CDialog::OnEraseBkgnd(pDC);
}

|
|
|
|
override OnCtlColor() and return the color of the brush , you want to paint the background. remember to put the flag to CTLCOLOR_DLG bcz u want to change the color of the dialog

Derive your own class from CSplitterWnd and handle WM_MOUSEMOVE and WM_LBUTTONDOWN. Do not pass these onto CSplitterWnd. That'll stop mouse operations. There may be a more elegant solution but this one is simple enough.

Derive a new class from CSplitterWnd. Lets call it mySplitterWnd. Then make the following changes:
void mySplitterWnd::OnLButtonDown(...)
{
CWnd::OnLButtonDown(...);
}
void mySplitterWnd::OnMouseMove(...)
{
CWnd::OnMouseMove(...);
}
BOOL mySplitterWnd::OnSetCursor(...)
{
return CWnd::OnSetCursor(...);
}
Trust in the code Luke. Yea right!
