Hi Everyone
How do you increase the font size of the text in CTreeCtrl?
thanks

You need to set a new font for the control. Normally I would do it something like this (assuming your control is part of a dialog)
OnInitDialog()
{
LOGFONT lf;
m_TreeCtrl.GetFont()->GetLogFOnt(&lf):
lf.lfHeight += 2;
m_Font.CreateFontIndirect(&lf);
m_TreeCtrl.SetFont(&m_Font);
}
m_Font needs to be part of your dialog class as it needs to live at least as long as the tree control using it. After setting the font, the tree control should work quite happily with it.

I want to use an example from msdn which tells how to set the proxy settings (Explorer). The problem is that my compiler doesn't know what PROXY_TYPE_PROXY is and many others. Those deifinitions are in the wininet.h but probably I have the older version cause there is nothing about in there. My wuestion is how to download (wininet.h), I do not need (and have no time) to download all sdk.
Maybe you know hot to change proxy setting for DUN ?
Please help.

Even if someone were to just give you the single .H file, there's no guarantee that it would work without the other files that go along with it. You would also need updated .LIB and .DLL files. Take the time to download the SDK, and burn it to CD. It'll be worth it.
If you are using a modem, go by a local computer store and see if they would be willing to download the file(s) for you, or maybe a friend has a fast connection that you could borrow for a bit. It shouldn't take very long, and will definitely be worth it. I'm using DSL at work and got all files downloaded during my lunch hour.

I'm looking for a grid control which enable to format the cells (font size, ...) like a rich edit control.
I've tried the Chris Maunder MFC Grid control, but I don't know how to do this with this control.
Does anyone know other grid controls?
Thks in advance!

Having implemented File Dragging / Dropping from Explorer into my application (using the DragQueryFile and DragFinish API), I know need to implement the reverse (drag/drop an item from my application into a directory location in the explorer window).
I assume that for this action my application will then need to receive the path location of the drop target from Explorer and then do what is necessary to create the file.
What technologies of the great and wonderful programming world do I need for this to be implemented.
Details are not necessary, I just need to be pointed in the right direction.cheers.

Hello
dwCopyLen = dwBufSize - dwSkipCount - HVD_HEADER_SIZE;
how can dwCopyLen become 821 when:
dwBufSize = 815
dwSkipCount = 0
#define HVD_HEADER_SIZE 1+2+4+1 //stx+USHORT+DWORD+char
strange huh?
If i split it to three lines:
dwCopyLen = dwBufSize;
dwCopyLen -= HVD_HEADER_SIZE;
dwCopyLen -= dwSkipCount;
I get the correct result.
Why?

This comes down to the order in which the operands are evaluated. Your first line expands to
815 - 0 - 1 + 2 + 4 + 1
i.e. 814 + 2 + 4 + 1 = 821
Do
#define HVD_HEADER_SIZE (1 + 2 + 4 + 1)
to get the results you are expecting!

ofcourse 
Why didnt I think of that? 
Many thanks!

Lesson 1:
Don't use macros unless you can't do without.
const int HVD_HEADER_SIZE = 1 + sizeof(USHORT) + sizeof(DWORD) + sizeof(char);
would have done the job.
Lesson 2:
If you have to embrace macros, embrace them correctly:
braces go 'round the entire expression, and each argument

Hi, I keep getting an error and I can't work out how to get rid of it
it is Error HC5011: cannot open the file E:\VC98\MFC....\afxhlp.hm
I think this is because I moved my project to a machine with a different path. How can I change the path the compiler uses?
Cheers
Andy

This is a file referenced in your projects .hpj (help file). Its a text file, so open it up and mod the path to the correct (new) location.

I am using VC6 on a 1.3ghz processor.
My project is fairly large (about 1500 files).
When I double click on a header or file in ClassView it takes up to 20 seconds to actually load it.
Also, during this time, MSDEV is taking >95% of the processor time.
Why?
Can I prevent it?

Do you have an excessive amount of breakpints set? (Check (under VC6) with 'Edit/Breakpoints')
Try deleting your *.ncb-file. It gets rebuild on the start of VC++6. That is my standard when soemthing strange happens.
My opinions may have changed, but not the fact that I am right.

I know others that have mentioned this behavior when opening a project with many files. The VS editor is just not built to handle such a big payload.

I have a DLL written in VB6(not sure) and need to use it from C++
I created manually .DEF file with names of all DLL functions and generated .LIB
(with LIB /DEF:MyDLL.DEF command)
But C++ adds name decoration if I declare imported function as stdcall,
so there are linker errors
e.g. MyFunc in DLL -> _MyFunc@16 in VC++
How to make it work?

|

Wrap the declarations with extern "C"
|
|
|
|
|
no way!
It forces the compiler to generate prolog/epilog code for C calling convention (caller adjusts stack pointer). It corrupts stack in my case becouse calling function uses __stdcall convention (callee adjusts stack before return from function)

I made an application with MFC, Doc/View architecture and MDI type. Now the users say that it is too hard to understand and they confuse with more documents. Is there a simple way to transform the program in an SDI type ? Or better, is there a way to limit the maximum number of ducuments ? (So I can keep the MDI for expert users).
Thanks.

You should be able to limit the open/new options by checking how many documents of your doc/view are already open.
In the ON_COMMAND_UI update handler for ID_FILE_NEW and ID_FILE_OPEN you should disable the option if the registered CDocTemplate object for that doc/view type has any open documents:
POSITION pos = pDocTemplate->GetFirstDocPosition();
pCmdUI->Enable(pos == NULL);
Depending on where you disable the commands, you may need to mod how you get the pointer to the CDocTemplate object.
Maybe:
POSITION pos = AfxGetApp()->m_pDocManager->GetFirstDocTemplatePosition();
CDocTemplate *pTemplate = AfxGetApp()->m_pDocManager->GetNextDocTemplate(pos);

Hi,
I need to write a litle kernel-mode code. I want to see what the following code will do in kernel mode.
<code>
.
.
.
return *((int *) 0);
</code>
Can I write a kernel mode code by using Visual Studio 7. (I do not have DDK)
And please make me some prediction that, what will the above code do in kernel mode.
thanx
karanba

I don't think this is kernel mode code. This is "I want to crash code"
MOV EBX,0
MOV EAX,[EBX]
RET
So, you're telling the compiler to load what's at address 0 and return it. There's nothing really important there, some compatabilty interrupt table stuff. But you'll just generate an exception, a crash, but nothing important.
To write in kernel mode, consult the DDK.
