Hi
Can anyone tell me how to execute a activeX control application in .Net framework?
I could compile but it asks me for "which excutable" when i try to run.
Thanks

You can't execute a control obviously. Add another project(exe) to the solution and make it the default project. In that project use the activex control you are making. Now when you take run, the program would get executed that houses the control.

Good morning
I am trying to port c++/MFC application to .net framework using MC++. With \clr option, everything works fine. But I am not very confident that it is the way as the object are not GC compatible yet.
What i wanted to know is .....is there a way i can test with accuracy that it is going to work on any platform? (that is with out problems) Can anyone tell me how?
If not, then is re-writing the code in MC++ the only alternative (this shud take lot of time)? I mean how is it simple as MS says to convert. Iam very new to .net, or new to windows programming itself. Your suggestions will be very valuable.
Thanks
Yogi

If you simply compile you app with /clr and add no __gc classes or use and __gc classes, then you haven't use the CLR at all. The /clr will add a dependancy to the application so that it won't run on a machine that doesn't have the .NET runtime installed. If all you're doing is /clr with nothing else, it's not worth using the /clr. Only use the /clr if you going to use any of the clr objects or routines.

I'm starting to get back into trying VS.NET with regards to Managed C++. Originally I found the IDE pretty clumsy (since everything I had known and fought to learn in VS6 had moved or morphed but its starting to get a little easier to understand.
I noticed that you can specify regions of code to be managed and unmanaged using the pragma directive, and was wondering how rigorously other developers used them? Do you explicity add the unmanaged command to the top of your classes, and then if a function does call managed code, this is then declared managed before unmanaging it afterwards? I was considering going all out C#, but there does seem to be quite a slow-down (and I'm still pining for the Doc/View architecture and Windows forms equivalent support for GUI extensions).
I'm still debating over weather to use a .NET assembly for data access, and then make use of C++'s interoperability to develop a largely MFC based client, but calling into managed classes for accessing data. I presume its possible to use managed extensions with ATL too -- I'll probably end up doing one or two shell extensions, and possibly a few Office add-ins
Thanks,
Paul

Generally I leave my code managed unless there is a good reason not to (performance, easier interop, etc.)

please read that code and solve mine problem
tmpProcess = new Process();
tmpProcess.WaitForInputIdle();
tmpProcess.StartInfo.FileName="f:\\mirc59t";
try{
tmpProcess.Start();
while(! tmpProcess.Responding)System.Windows.Forms.Application.DoEvents();
}catch{}
tmpProcess.WaitForInputIdle();
IntPtr hWnd=tmpProcess.MainWindowHandle;
Srm=new send_recive_messages(hWnd);
/*/////////////////////////////////////////////////////
managed public __gc class send_recive_messages constructor
////////////////////////////////////////////////////*/
send_recive_messages::send_recive_messages(IntPtr par_hwnd)
{
CString cstr="";
LPTSTR str="";
hwnd=(HWND)par_hwnd.ToInt64();
//////////////////////////////////////////////////////////
HWND h=GetWindow(h,GW_CHILD);
//////////////////////////////////////////////////////////
}
///////////////////////////////////////////
h variable recive null that's why remaining code could not run.
it should not recive zero because the process main window
contain two button and four Static members.
can any body tell why it recive 0?
and what i have to do that it should not recive zero?

Could someone please tell me how I would do the following cast/conversion properly? It's late and my brain no longer functions.....
Object* oFields[] = new Object* [iFields];<br />
oFields[i] = (Object __gc* )DateTime::Parse (sData.c_str ()) ;
the compiler currently tells me
error C2440: 'type cast' : cannot convert from 'System::DateTime' to 'System::Object __gc *'
give me c# any day
Thanks
Stephen.

Stephen -
DateTime is a value-type; it needs to be boxed first before it can be held in an Object array:
oFields[i] = __box(DateTime::Parse(sData.c_str()));
In C# boxing is done for you by the compiler (implicit boxing). In C++, because of the performance overhead associated with boxing, boxing is an explicit operation.
Give ME the full power of C++ any day

Cool!
Maybe I'll quote you in my next MC++ article. Last time I quoted you, you had used a newly invented word - "performant" - but this time your language was more conservative

The C++ language, compiled for the .NET platform. A set of language extensions expose functionality of the platform itself - garbage collection, the common type system, etc.

How to Use the ToolBoxBitMap Attribute for a control Created using ManC++.
I tried the way it is done in C#, but I get an Error (Undeclared Identifier) for the Type parameter of ToolBoxBitMap Attribute .
namespace XYZ
{
[ToolboxBitmap(__typeof(MyControl))]
public __gc class MyControl : public UserControl
{
};
}
The Project also have a bitmap(with the name MyControl.bmp) as a resource.
Where am I going wrong ?
Thanks,
Firoz

Firoz --
I've been meaning to upload an article on this...
__typeof() doesn't work on types that haven't been fully parsed by the compiler; this will be fixed in a future release. As a workaround, place a dummy class ahead of your MyControl class and specify it instead:
namespace NickHod
{
namespace Multimedia
{
private __gc class ThisAssembly
{
};
[ToolboxBitmapAttribute(__typeof(ThisAssembly), S"CdDrive.bmp") ]
public __gc class CdDrive :
public System::ComponentModel::Component
{
The next trick is to name your bitmap using the fully qualifed namespace where the dummy-class lives. In my example above, the bitmap filename is "NickHod.Multimedia.CdDrive.bmp"
In the Linker/Input settings for your project, specify this bitmap under "Embed Managed Resource File" (the linker switch is /ASSEMBLYRESOURCE).
The other thing you'll need to do is use sn.exe to genereate a strong-name for your assembly (specified in AssemblyKeyFileAttribute() in AssemblyInfo.cpp), then register it in the GAC with gacutil.exe.
Good luck!

Hi,
I am looking for a way to convert a double to the char representation, ie. put double, which is eight bytes, to char[8];
Example:
double nDb = 12.34;
char szDb[8];
szdB would hold the character representation of nDb which might look something like:
[0] 0''
[1] 0''
[2] 0''
[3] 0''
[4] 0''
[5] 0''
[6] 51'3'
[7] 64'@'
Thank you.

For native or managed code?
Something like the following would do the trick:
(in native code)
memcpy(szDb, &nDb, 8);
(with a managed array)
char __pin* temp = &szDb[0];
memcpy(temp, &nDb, 8);

I have a general question. I am using fread(...) fn in my program. I created a FILE *inFile to point to the file that i opened for read. (ie. inFile = fopen("c:\\document.bnm","r"))
I am reading 20 ascii characters at a time from the file and then send them out thru the serial port ,....i keep doing this until the end of file is reached. My file opening and reading is defined in one class called COpen and my serial communication routines are defines in a class called Tserial_event.
Once I call the function from COpen to send data thru the serial port (
com->sendData(), where com is an object of class tserial_event) and the program jumps to where the sendData fn is defined the value of inFile is lost!!!!!!!!! Originally it points to location 0x1027a898, when it jumps to sendData() it becomes 0x0000000??? and then when it returs to the fread statement to raed the next 20 characetrs it crashes, saying that I am raeding at an invalid location obviously because my pointer was lost.
My question is how should I define inFile so that it wouldn't change value when I uump to another class.
I NEED HELP ASAP IF SOMEONE CAN HELP ME
