I want to have my compiled html help point to a topic specific to where the mouse is pointing but I can't seem to determine which control the mouse is hovering over.
private: System::Void FrmMain_HelpRequested(System::Object^ sender, System::Windows::Forms::HelpEventArgs^ hlpevent)
{
Point pt = this->PointToClient(hlpevent->MousePos);
Control^ requestingControl = dynamic_cast<control^>(sender);
Control ^ctrl = this->GetChildAtPoint(pt);
Control ^ctrl2 = this->ActiveControl;
if( File::Exists(this->helpProvider->HelpNamespace ) == true)
{
Help::ShowHelp(this, this->helpProvider->HelpNamespace);
}
}</control^>
ctrl is the form itself and crtl2 is the last active mdichild in my application.
requestingControl returns the form and not the item the mouse is over.
Hope someone can help

Hi,
have a look at the sender parameter, I expect it to hold the current control; the only thing
required typically is a cast.
|
|
|
|
|
It does not.
The control is the form not the menu item. I have updated my code.
Thanks for the suggestion.

Hi Glenn,
that's too bad, I don't know then.

I am definitely a newbie....
I'm trying to pass a path to a function that calls 'ShellExecute'...
I know that ShellExecute only recognizes path with '\\' in it.
I don't want the user to have to put '\\' in place of '\' in their path.
example:
real path > c:\thisfolder\thisfile.txt
c++ code > c:\\thisfolder\\thisfile.txt
does anyone know what I can do to figure this out...?

You can use the Replace method from the String class in your code.
yourString.Replace("\\","\\\\"), where yourString contains the real path.

If you're getting a string from the user, you shouldn't have to
worry about this.
The "\\" is only used in string literals in your code. This is
necessary because a single '\' in a string literal starts an escape
sequence. When you use \\ in your string literals, the compiler will
convert it to \

I've seen this happen with C# 2008 Express Edition on my desktop machine, but it works fine on the laptop.

Hello, I'm not sure which topic to post this kind of problem.
If I ask on the wrong board, please let me know.
I write a windows form project with CLR supporting, and I want to
package it into an exe file.
I run the exe file in the Debug folder. It works on my computer, but not on other's computer which doesn't install .NET.
But I want the exe file to be portable and without install.
It seems that it needs a .NET environment.
I try to install .net framework 2.0 to the computer which doesn't install Microsoft Visual Studio 2005.
But I still can't open the exe file, too.
Is it possible to create a exe file without install in Microsoft Visual Studio 2005?
Thx for ur reply.

Yes. The MSDN documentation has information detailing deployment issues of Visual Studio C++ projects, well any type of Visual Studio project actually.

A program written using /clr should run on any computer with .Net framework installed. Make sure that
1. The program in 100% .Net /clr then you can just install dotnetfx
2. Also check which version of .net are you targeting
3. If you are doing a mixed assembly, make sure you deploy appropriate CRT/OpenMP/ etc DLLs as well,
you can distribute using vcredist<arch>.exe or MSMs.
4. And finally, you need to distribute applications built in Release mode not Debug mode. Debug DLLs cannot be distributed.

#include <stdio.h>
#include <conio.h>
int main(void)
{
/* request auto detection */
int gdriver = DETECT, gmode, errorcode;
/* initialize graphics mode */
initgraph(&gdriver, &gmode, "");
/* read result of initialization */
errorcode = graphresult();
if (errorcode != grOk) /* an error occurred */
{
printf("Graphics error: %s\n", grapherrormsg(errorcode));
printf("Press any key to halt:");
getch();
exit(1); /* return with error code */
}
/* draw a line */
line(0, 0, getmaxx(), getmaxy());
/* clean up */
getch();
closegraph();
return 0;
}
But this programme show error while linking after compilation,

Wrong forum, you should ask similar questions to the MFC/C++ one.
Anyway, initgraph is a TurboC function, you have to use that compiler (if I remember well it's free at Borland website). Have a look at
http://electrosofts.com/cgraphics/index.html[^]
to know all requisites you need in order to link correctly.

Hi, all:
I'm migrating code from VS2003 to VS2005, (using /clr without :oldsyntax) and have hit a strange problem. I have a control class with properties. They used to show up (VS2003) in the application using the control (in their own category) - but now nothing.
Here's a piece:
[Description("Total Number Of (Unsuccesful) Logon Attempts Before Failure"),Category("Logon_Dialog")]<br />
static property int LogonTries {<br />
public: int get() { return retries;}<br />
public: void set(int NumTries) { retries = NumTries; }<br />
}
Searching all about on MSDN, I finally came up with an example. Alas, it looks just like what I have! (Thanks, again, Microsoft)
How do I get a property to show up in the property list for the control?
Thanks,
Balboos

Hi
May be it it a very silly thing but I don't know to how to do it.
In my VC++ application where I have a form with some control on it. I want to copy this form with control and paste to a different project.
In solution explorer, I have a file form.h and form.cpp file and there is a .resx file which is under the form.h file. If I simply copy these three files to another project, I can not open it is designer view.
How can I copy this form with controls on it and add paste it to another project with its control and still able to open it in designer view.
Any link or avdise will be helpful.
Thank you.

You can actually copy any winform from one project to another no matter what the language is. All you have to do is open the form in the designer and hit ctrl+A to select all the controls, then hit ctrl+c to copy the controls and Ctrl+P to paste the controls in the other project.

Hi All,
I have to handle text files of larger sizes ranges from 10GB and more which are exported from some application softwares. The text files contains the required information scattered throughout the file. I need to gather all those information in a particular format to do further analysis. Say for example, if the input file contains as following:
#10 // time stamp 10
0!
1(
1=
#15 // time stamp 15
1!
0:
I have to gather the information as,
! 10 0 15 1
( 10 1
= 10 1
: 10 0
So please suggest me how to store the above gathered information either as a vector, class arrays, or anything else like database e.t.c., The information surely occupies size larger than 10GB. And i have to access the gathered information for further progress.
With Regards,
Sangeetha.

I would not read the whole file into one data type. I would push it into an arraylist and pop it out after I saw the timestamp and write it to the new file.

Sounds to me like if you pasted your code, we'd be able to see your error and help you.
