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

Hi All,
I have some old Visual C++ code that I think would
work well as a "web service".
Is it difficult to convert my existing VC++ code
to .NET code?
Does that even make sense? Please help!

I guess there is no definite answer. I am assuming you would write the web service in Managed C++, so at least some of the code could port over with ease. You would basically just want to rewrite the application from scratch, referencing your existing app. for logical aspects. If your existing code is complex and convoluted then your web service very well could be too. Using Visual Studio.NET will definitely help you in the web service arena.

First off I'm absolutely new to the .NET environment all together.
I recently bought Visual Studio .NET academic. I wrote a small web service in managed C++ but it keeps telling me that I must have IIS installed to run the service. Is there any other way to test this without running IIS? It's not that big a deal I'm just playing around with .NET at home. Just curious.
nay

You can definitely consume a web service without IIS, as to providing a web service I beleive they provide xml/soap messages via http, that is why they are so popular, distributed over a common protocol like http. So you are probably going to need a http server, it doesn't necessarily have to be IIS, I don't think.

Can you use MC++ as your code-behind for ASP.NET page ?

ASP.NET pages and ASP.NET XML Web Services files contain server-side logic (as opposed to client side logic) written in Visual Basic .NET, C# .NET, or any .NET compatible language. Source [http://msdn.microsoft.com/net/aspnet]
The above would make one beleive MC++ could be used for ASP.NET, the statement may be true, but I guess MS is assuming you will write the plumbing coding for the ASP_RUNTIME to recognize and compile MC++, not sure why they make this statement 
Thanks.

Web services can definitely be written using MC++, but MC++ does is not supported by ASP.NET.
