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

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.
