I have created a tablelayoutpanel with 2 columns. data is being retrieved from sql server and linklabels are being generated at runtime for each data in the tablelayoutpanel. My question is how do i generate a click event on the linklabel created at runtime inside the tablelayoutpanel.
very urgent.
thanks
Maneesh

It's done the exact same way you wire up any other event in C#. Lesson 1[^]

Hey there
It seems that from .Net 3.0 and onwards the System.Speech assembly was added: Article[^]
Hope this helps

Hi All.
I have been developing a program in c#. the program connects to a database. When the program is run on a windows 7 x64 bit OS, it gives the following error:
System.InvalidOperationException: The 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine.
The computer does have MS Office installed.....
Is there anyway that I can get the program to work, as I have heard that Windows 7 x64 has a lot of compatibility issues.
Thanx

Right now, your code is being compiled for "Any CPU", which will generate 64-bit code is running on a 64-bit CPU. Since there are no 64-bit drivers for Access databases, and you cannot mix 64 and 32-bit code in the same process, you'll get this message.
You have to force the code to compile 32-bit only. Go into the Project Properties and change the Target CPU to "x86", then recompile.

Hi,
I had this problem once,but now it has been solved.
my solution is to change the IIS settings.
you only need to set the Enable 32-Bit Applications=true(IIS 7),and it works.
best regards.

dll generated by vc++
__declspec(dllexport) long __stdcall LPRLoadImage( const char* pFilePath, LPRImage** ppImage );
and LPRImage is a struct,defind as
struct LPRImage
{
int nSize;
int nChannels;
int depth;
int nColorMode;
int dataOrder;
int origin;
int width;
int height;
int imageSize;
unsigned char *pData;
int step; SYSTEMTIME timeStamp;
};
how can i call LPRLoadImage in c#,help me!!!!

You need to declare a function prototype and decorate it using the DllImportAttribute class. You also need to declare a struct corresponding to LPRImage and decorate it with the StructLayoutKindAttribute class using LayoutKind.Sequential . Make sure your struct elements are the same size (in bytes) as the C++ data types. You should be able to use the same types for everything except SYSTEMTIME and unsigned char *.
This link[^] is a good place to start finding the information you need. You'll especially need to know about this[^] and this[^].

autually ,i had declare the prototype as below:
[StructLayout(LayoutKind.Sequential)]
public struct LPRImage
{
public int size;
public int nChannels;
public int depth; public int nColorMode;
public int dataOrder;
public int origin;
public int width;
public int height;
public int imageSize;
[MarshalAs(UnmanagedType.ByValArray)]
public byte[] pData;
public int step;
public SYSTEMTIME timeStamp;
}
public static extern int LPRLoadImage([System.Runtime.InteropServices.InAttribute()] [MarshalAsAttribute(UnmanagedType.LPStr)] string pFilePath, ref System.IntPtr ppImage);
but i don't know how to call the LPRLoadImage function,because ppImage is a pointer,i call like below:
LPRStructure.LPRImage Image = new LPRStructure.LPRImage();
IntPtr pImge = Marshal.AllocHGlobal(Marshal.SizeOf(typeof(LPRStructure.LPRImage)));
Marshal.StructureToPtr(Image, pImge, false);
int i = LPRRender.LPRLoadImage(s, ref pImge);
when i run this,the return value i = -2 [-2 :invalid parameter ]
i think the ppImage is a pointer which point to the pointer of struct,how can i transfer the ppImage parameter to the function?

I think the call to StructureToPtr is causing the problem. Your code should look similar to the listing below (which I haven't tested):
IntPtr pImge = Marshal.AllocHGlobal(Marshal.SizeOf(typeof(LPRStructure.LPRImage)));
int i = LPRRender.LPRLoadImage(s, ref pImge);
LPRStructure.LPRImage Image = (LPRStructure.LPRImage)Marshal.PtrToStructure(pImge, typeof(LPRStructure.LPRImage));

thanks for u replay,but i test it,the LPRLoadImage return value is also -2 ,i don't know how to understand the LPRImage** ppImage in c++

You can call Win32 DLLs in C# with P/Invoke:

Hi,
I use the following code to open a folder1 with window explorer and with file1 inside select. But the problem is that if the desktop has a file with the same filename as file1, it will select the desktop file instead of selecting the right file1 in the folder1 ! Why ?
Process p = new Process();
p.StartInfo.Filename = file1;
p.StartInfo.WorkingDirectory = folder1Path;
p.StartInfo.Arguments = "/Select," + file1;
p.Start();
Thanks

Hi,
I think you were quite lucky that your arguments actually started Explorer.
Review this http://support.microsoft.com/kb/307856/en-us[^]
I would have tried this (not tested):
Process p = new Process();
p.StartInfo.Filename = "explorer.exe"
p.StartInfo.Arguments = String.Format("\"{0}\" /select,\"{1}\"", folder1Path, file1);
p.Start();
where folder1Path and file1 are both fully qualified.
Alan.

I think you can use FindWindowEx to get the SysListView32 of Windows Explorer, then use SendMessage with LVM_SETITEMSTATE to select the items. The difficulty is to know the position of the items. Perhaps LVM_FINDITEM can be used for this. In this way you can also select multiple files.

Dear developers,
I am coding a very small project for my study. I want to refresh form1 after form2 is closed. For example, I open form1 and click one button to open form2 and in form2 I can insert data to the database (ex : tblItem). In addition, combobox in form1 retrieves data from the database (tblItem) too. So, after inserting data from form2 and when I close the form2, I want the comboxbox in form1 refresh to retrieve the last update of tblItem data.
Here is my code to open form2
form2 frmitem = new form2();
frmitem.ShowDialog();
Please advise, thanks.

You can paste your code directly behind the ShowDialog() row. If you call the ShowDialog() function, the main form will "sleep" until the dialog window is closed.
For example, if you call ShowDialog(), and on the next line you call Messagebox.Show(), the messagebox will be shown as soon as the dialog window is closed.
So your code might look like this:
form2 frmitem = new form2();
frmitem.ShowDialog();
UpdateMyComboBox();
