Hi to all, I'm new to vc++ and I've read a bit on how to create a new form and load it (make it appear on screen). But i have this code and its corresponding error and would be glad if someone could point me in the right direction.
There's three forms, Form1 (login form) and gymMain a main interface. So what I tried to do is first load the application with gymMain and make its Visible state FALSE, next load Form1 (login) and upon confirmation of input, close Form1 and make gymMain visible. Now I try this with the below code and the erorr is shown below. All help/suggestions appreaciated.
regards
PS: I'm prety sure I used the header files appropriately but one never knows, ...

#include "stdafx.h"

#include "search.h"

//using namespace Form1;
//using namespace gymMain;
//using namespace NewMember;
//using namespace search;
[STAThreadAttribute]
int main(array ^args)
{
// Enabling Windows XP visual effects before any controls are created
Application::EnableVisualStyles();
Application::SetCompatibleTextRenderingDefault(false);
// Create the main window and run it
Application::Run(gcnew gymMain());
return 0;

As said earlier Form1 doesn't seem to member of GymManager, which is assumed by you while coding.

If I have a populated dataGrid in visual c++, how can I get values from the dataGrid without going to the underlying dataSet.
Is there a way to use dataGrid->currentRowIndex to reference the row and then return the value from a given column.
Thanks!!

You need to populate the dataset...

How do I perform a global hit test?
I want to translate the mouse coords to a global hit test result which will hopefully give me the window handle that the mouse is over and if possible, if I am over the title bar/menu/status bar etc.

Hi everyone,
I set my main form's icon. When I tested it in debug mode, a System.Resources.MissingManifestResourceException gets thrown by at the point where the forms designer code attempts to load the icon:
this->Icon = (cli::safe_cast<System::Drawing::Icon^ >(resources->GetObject(L"$this.Icon")));
When I view the .resx file in VS however, I can see the icon is there. Does anyone know what the cause of this problem could be?
TIA,
Ralph

I discovered that my form was declared inside a namespace `Configuration1'. The name of the project is `Configuration'. Changing the namespace to `Configuration' seems to have solved the problem.

II would like to capture the word (text) under the mouse from any program in real time. If the mouse pauses over a word, I would get a callback or notification that includes the actual text. This would not be limited to my own program. I want to catch the text on any program.
I know I could watch the clipboard and use cut or copy to get the text from another app.
I want to make a program that checks the word against a local word table so that my program window can show information about the word the mouse is over.

Are you using C++/CLI, or are you in the wrong forum ?
there's an API called GetWindowAtPoint ( from memory ), which would allow you to call GetWindowText. Getting the word under the mouse is a little harder.

Looking for someone who has basic knowledge of writing a AMX plugin for CS 1.6
Basically it has to take a command the admin does and store it in a text file on a server to check for proof of admin abuse.

What's CS 1.6 ? It supports .NET ?

Counter-Strike 1.6.
The admin commands are input through Steam at www.steampowered.com
I tried to google to see if Steam supports .NET but nothing came up
-on the other hand-
There is a "guide" at www.amxmodx.org on the constants and such. They also have downloadable plugins and you can open the .sma files in notepad. The following is a link to plugins that record stats:
http://www.amxmodx.org/compiler.php?mod=2&cat=3&plugin=&author=&go=search[^]
So pretty much when admin uses: amx_kick or amx_slap or amx_ban it needs to record his STEAM id and write it to a text file in the database.

Hi all,
I'm having trouble with my multithreading. I am doing video capturing so have and infinite loop in which frames are captured, unfortunately while the thread is running the class (containing the loop) the UI freezes.
I'm wondering if anyone knows how i am able to create a simple worker thread which executes the class and keeps the UI responding?
Here is the code that executes the class. I have attempted to create what i thought was a worker thread, with no avail.
<br />
private: System::Void button2_Click(System::Object^ sender, System::EventArgs^ e) {<br />
<br />
ThreadStart^ t1 = gcnew ThreadStart(this, &FYProjV4::Form1::detectThreadStart);<br />
Thread^ recogThread = gcnew Thread(t1);<br />
<br />
recogThread->IsBackground = true;<br />
recogThread->Start();<br />
<br />
<br />
}<br />
<br />
private: System::Void detectThreadStart() {<br />
<br />
if(reportBox1->InvokeRequired == false)<br />
{<br />
<br />
FaceRecognition recogTools;<br />
recogTools.StartRecognition(reportBox1, faceBox1);<br />
}<br />
else<br />
{<br />
<br />
this->BeginInvoke(gcnew DetectThreadStartDelegate(this, &FYProjV4::Form1::detectThreadStart));<br />
this->EndInvoke(result);<br />
<br />
}<br />
<br />
}
I am in a real rush to get this sorted so any suggestions would be greatly appreciated.
Also, Removing the loop is not an option and it must be in managed c++.
Thanks for your time

this->BeginInvoke causes the call to be executed on the main thread, so you're still blocking the main thread while StartRecognition runs (and the worker thread just waits at this->EndInvoke).
You have to run the code that takes a long time on the separate thread and Invoke only for the parts that update the UI.

With VS2005, I'm having a problem figuring out how to get new directories (from dirctx SDK Feb 2007) to be added to the standard ones.
I have tried Tool / Options, Project Options "Additional Included Directories" (/I), and cannot get it to work.
Clearly I'm missing the boat on this one... help.

How do I disable the com1 port from being used by the debugger? I am writing a Mobile 5.0 application which uses com1 and it is in conflict with the debugger. Thanks.

Do you want to use C++/CLI, or just vanilla C++ ?

Hello,
Under certain conditions, I would like my C++/CLI Windows Forms application (i.e. its main form) to show up maximized in the foreground, even if it is minimized or under other windows. Unfortunately, BringToFront and Focus functions don't help.
I have even imported and called the SetForegroundWindow API, with no effect:
[System::Runtime::InteropServices::DllImport("user32.dll")]<br />
extern bool SetForegroundWindow(IntPtr ^hWnd);
I call the code in Click event of the System::Windows::Forms::NotifyIcon component, and it gets called, but it has no effect.

I think you will need to import and call ::SetWindowPos()
System.IO.Path.IsPathRooted() does not behave as I would expect

There's a WindowState property, from memory. There is certainly a property that takes an enum for maximised. And, TopMost is a property you can set to true.
