There is an article located here:
http://www.codeproject.com/listctrl/headerctrlex.asp
It explains how to create a multiline header control. I
tried implementing this article for a CFormView, but I
can't get it to work. Too many errors. Can someone
show me how to implement this article for a CFormView?
Please, please, any response any one can give me
me will be greatly appreciated. Demo projects are
beloved.

Is there any way of loading a bitmap to a CBitmap from file? I've got a lot of images and don't want to load them with the resource editor.
Thanks.
|
|
|
|
|
Yes, LoadImage
HANDLE LoadImage(
HINSTANCE hinst,
LPCTSTR lpszName,
UINT uType,
int cxDesired,
int cyDesired,
UINT fuLoad
);
using the value LR_LOADFROMFILE in the Load Flags.
Then use CBitmap::FromHandle

if "bitmap" means "BMP", try ::LoadImage

In ADO you usually get all your values as Variants, Is there a easy way to convert any type into a string or BSTR
|
|
|
|
|
Yes,
var.bstrVal returns a BSTR type.
Cheers!!!!
Carlos Antollini.
|
|
|
|
|
No!
I meant is there functionality that can convert any variant type e.g. int, long, double, currency to a BSTR.
A microsoft Example has a CrackStrVariant function, but this does not cover all types.
|
|
|
|
|
I came across this problem recently, and found the perfect solution
use _variant_t wrapper class
e.g. converting a long to a BSTR
_variant_t vLongVal((long)100);
vLongVal.ChangeType(VTV_BSTR);
_bstr_t vBstrValue(vLongVal.valbstr);
This can be applied to any type
I hope this helps

Look for this article in the MSDN:
VARIANT and VARIANTARG

Hi,
How is possible to create a Bitmap with different bits per pixel.
I've tryed with CreateDIBSection but when I select the Bitmap into the DC and then draw into it, nothing is happened.
Is there any example of this?

i want to get a recordset from server database using ADO command which calls stored procedure.
the subroutine source code is following...
with a global connection and a global recordset pointer,
////////////////////////
try
{
_CommandPtr pCommand ;
HRESULT hr = pCommand.CreateInstance( __uuidof(Command) );
if( FAILED(hr) ) return FALSE;
pCommand->ActiveConnection = GetConnection();
pCommand->CommandText = proc; // stored procedure parameter : @roomNo smallint
pCommand->CommandType = adCmdStoredProc;
pRecordset = pCommand->Execute( NULL, argv, adCmdStoredProc );
// pRecordset->Open((IDispatch *) pCommand, argv, adOpenStatic,adLockOptimistic, CmdStoredProc);
}
catch(...)
/////////////////////////
when returns from the above subroutine, the global recordset becomes closed.
so, can not get a record by using pRecordset->GetCollect(0L).
why this occurs ????
somebody help me.....
thanks in advance.

Are you sure your Execute is working ?
try adding a
catch(_com_error e)
and see if it catch these com errors, If it does then see the error description

I have a CFile member variable who seems angry with me because doesn't do what I want.
Here's the code
in MyClass.h:
public:
CFile* myFile;
in MyClass.cpp:
CMyClass::CMyClass()
{
myFile = new CFile;
}
CMyClass::~CMyClass()
{
delete myFile;
}
//My class is derived from CPropertyPage
BOOL CMyClass::OnInitDialog()
{
if (myFile->Open("some.file", CFile::modeRead))
{
//Dosomecode
myFile->Close();
}
}
And I get:
Debug Assertion Failed!
// More things
Expression: _BLOCK_TYPE_IS_VALID(pHead->nBlockUse)
// More things
Since I'm learning C++ and I don't understand what is happening, I need somebody to help me and show that stupid file who is the programmer and not to crash again.
Thanks in advance,
|
|
|
|
|
The assertion happens when you delete right?
(2b || !2b)
|
|
|
|
|
Yes, I think so.
The application opens a property page and it crashes when I close it, but if I debug it it goes to HandleMap::DeleteTemp or something like that.
|
|
|
|

I think you should delete the file pointer not in the window destructor but add an event OnClose and then delete the pointer there, if it doesn't help than u can send me your project to pudaoman@hotmail.com and i'll try to hel you.

Hallo out there,
I have a little problem. I want to write a programm in MFC which opens an IE and give him some attributes like open in fullscreen and a start page. I haven't found anything in the msdn about this possibility so i hope that you can help me. Perhaps there are other possibilities to menage this problem.

Hello, the codegurus around the world.;)
We can open IE in our program by ShellExecute, WinExec, or CreateProcess.
IE might keep the start page URL and full screen info in the registry.
Or, the full screen status may be made by some command line argument.
Have a nice day!

or you can just send F11 key to the IE in order to make it full-screen
use keyb_event (or sth like that, i am not sure about it) to send the keystrokes to IE

I have a program that maintains a list of files. The operator is allowed to open these files which I do by calling ShellExecute(). What I would like to know is how to tell if the program started by ShellExecute() is still running when my program terminates. Is this possible?
Thanks for any information you can provide.
Steve.

Try using ShellExecuteEx instead and collect the hProcess member of the returned SHELLEXECUTEINFO structure.
What to do with the hProccess is another story, maybe someone else can help?
Alternatevly use CreateProcess, which gives more control.

Hey. use ShellExecuteEx api and in it's parameter structure check the hProcess data member after u launch your process, it should contain a handle to your process, after that you can do some stuff with the handle ussing api, depending on what you want.
