If you are using a Visual Studio Setup Project, open the File System Editor. Right-clicking on the root node, you can select Add Special Folder->User's Desktop. Then, right-clicking on the folder content, you can select Create New Shortcut to add a shortcut to your application execurable file.

This will return an autoComplete TextBox with the Greek leters as custom source.

private TextBox CreateAutoCompleteTextBox()
        {
            TextBox result = new TextBox();
            AutoCompleteStringCollection autoCompleteStrings = new AutoCompleteStringCollection();
            autoCompleteStrings.AddRange(new string[]{
                "Alpha",
                "Beta",
                "Gamma",
                "Delta",
                "Epsilon",
                "Zeta",
                "Eta",
                "Theta",
                "Iota",

            });
            result.AutoCompleteCustomSource = autoCompleteStrings;
            result.AutoCompleteSource = AutoCompleteSource.CustomSource;
            result.AutoCompleteMode = AutoCompleteMode.Suggest;
            return result;

Yeah - the built in autocomplete doesn't work with multiline. You'll need to 'roll your own' control to do this I think.

Retrieve array from unmanaged DLL into C# application

User 127827-Apr-09 2:38

7-Apr-09 2:38

I'm trying to get an output array from a function in an unmanaged DLL into my C# application. I've already done some googling on this topic and while I've found some articles, none of the suggestions seem to work.

The DLL has a function prototype of

int GetData(int ID, float* Results)

The int that is returned is the length of the array

Internally to send the results back it does

Results=new float[length];
//Fill in results here

In my C# application I use a delegate to get the function results:

[UnmanagedFunctionPointer(CallingConvention.Cdecl)]
private delegate int delGetData(int TagID, ref IntPtr Results);

I then try and retrieve the results and copy to a managed array doing this:

IntPtr data=IntPtr.Zero;
int Len=GetData(ID, ref data);

if(Len==0)
//something happened, exit

float[] results=new float[Len];
Marshal.Copy(data, results, 0, Len);

I always get an exception on the Marshal.Copy because the source (data) is null.

I have some control over the unmanaged DLL, any suggestions on how to get these to interface?

Thanks

You can use P/Invoke[^] and marshaling arrays[^].

Hi,

If data gives a NullReferenceException, something must be wrong in the unmanaged code; here are some possibilities:
1. a silly mistake, say "return 0;"
2. your function pointer (accepting the delegate) not being defined as __stdcall
3. something going wrong with parameter alignment on stack (native long=32 bit, managed long=64 bit;
native char=8 bit, managed char=16 bit); this assumes your post was showing simplified code only.
4. IntPtr needs a 4 or 8 byte pointer, depending on Win32/Win64; your native code must match that.

As far as P/Invoke goes:

I prefer to allocate arrays, structures, objects on the managed side, and somehow pass their pointer to the unmanaged world; this has the advantage of being a managed object from the start, and not requiring any copying, and the disadvantage it is difficult to achieve when there are unknown values, such as the array size.

However, you are using a delegate to pass results, so you could instead use two delegates:
- one to inform the managed world about the array size, and ask for an array pointer;
- one to signal the managed world the array has been filled.

Passing a pointer can be done in two ways:
- with the "fixed" keyword; simple, unless the array must remain fixed afterwards, as in your case.
- with the GCHandle class; don't forget to eventually free the handle!

BTW: you were using the ref keyword, "out" would have been more appropriate.

Smile | :)

Hi
I have an excel project with two columns Number and name, where Number contains ('4114','8900','3311-123-2').

I read it in c# using:

string connectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\\temp\\test.xls;Extended Properties=""Excel 8.0;HDR=YES;""";
command.CommandText = "SELECT Number, Name FROM [Projekter$]";
string nummer = dr["Number"].ToString();

The problem is that '4114','8900' are displayed correct, while '3311-123-2' is empty.

Can anybody please help me?

kindly guide me what i have to do and how penal i should be arrange for my task.

Use event KeyDown, if for example CapsLock pressed, then set the image in statusbar.
For example, you are using ToolStripStatusLabel, then set it to :
toolStripStatusLabel1.Image = ((System.Drawing.Image)(resources.GetObject("toolStripStatusLabel1.Image")));

Use the designer, and see the code behind it in ...Designer.cs.

Here you go,

Add images caps_on and caps_off in the resources,
then add below code into your form class..

private bool bCapLock = false;
protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
{
    if (keyData == Keys.CapsLock)
    {
        if (!bCapLock)
        {
            toolStripStatusLabel1.Image =  Properties.Resources.caps_on;
            bCapLock = true;
        }
        else
        {
            toolStripStatusLabel1.Image = Properties.Resources.caps_off;
            bCapLock = false;
        }
    }
    return base.ProcessCmdKey(ref msg, keyData);
}

Hope this can help.
