Thank you everyone for your help. I actually meant to post this message in the vb.net section. I hadn't had to do this conversion in a long time so I forgot the function for doing it. I just rememebered today the asc() function in vb.net does this. Although I'm not sure if it would work for any unicode characters.
I'll also try a vb form of the c code you gave me Thomas. That might work if I ever have to deal with a unicode character.
I appreciate everyones help,
Mike

The Asc function will work just fine with Unicode characters, despite it's name. ASCII was brand new when BASIC was created back in 1963, but now it's kind of outdated...
You should move on into the .NET world, though, and just convert the character to an integer as Thomas suggested. That's what the Asc function does anyway, it's just a wrapper for the real .NET method.

The code I wrote was written in Visual C# so it should be easier to convert to VB than if it was in C (which I don't even know  ). The code is also is not specific to unicode characters. The Convert.toInt32(Object obj) is a standard method in the .NET framework.

What about this:
Int32 x = Int32.Parse(string);

In DataGridView, I'm wanting to create a column of buttons with bitmap faces instead of text. No sweat doing the buttons using DataGridViewButtonColumn. However, I've not found a simple way to put a bitmap or icon on the button face. Anyone done this?

I am working with large bitmaps (in the range of 5000x5000 pixels) and found no support for loading the image with gray scale. The only supported 4 and 8 bit format is colour, what I found online was the 16 bit format doesn't work. Using a gray scale conversion after the fact was very time consuming. In the end I changed the palette of the 8 bit format using the following code
ColorPalette pal = segyBMP.Palette;
int j = 255;
for (int i = 0; i < pal.Entries.Length; i++)
{
pal.Entries[i] = Color.FromArgb(j, j, j);
j--;
}
segyBMP.Palette = pal;
(The decrementing j is to reverse the black/white - saves me else where is the code.)
Does anyone know if there is a gray scale palette already in the system so I wouldn't have to make my own? Or a better way to handle the gray scale issue? I don't want/need colour and size does matter. I want to keep it to 8 or maybe 4 bit format.

AFAIK there are no ready-made palettes whatsoever, and I cannot imagine a simpler
way to construct the one you are using.
I trust you use images with PixelFormat=Format8bppIndexed.

Interesting. The 16 bit format is interesting, because it stores partial color values. However, it certainly 'works'. 4 and 8 bit have palettes, anything higher, doesn't. My image processing articles show how to convert 24/32 bit to greyscale, making it work with 16 bit is pretty easy.

No, a palette is just a palette.

I'd be inclined to convert to 24 bit, convert to gray with a color matrix, and convert back. I'm not sure which would be faster, but that seems less error prone.

If it's urgent, then learn to use google. It is not good form to say that something is urgent, because while it's urgent for you it doesn't affect me one way or the other. Why should I be inconvenienced by your lack of planning?
As a hint, take a look at BrowsableAttribute.

Hi, all!
I have a following problem, and i can't find a right solution.
Description:
There is a COM server written on C++ and it works through IDispatch and it does't have a TYPELIB. And from another side there is a COM client developed on C#. Through LATE BINDING it uses a COM server
and COM server sends different events to client, but i can't implement COM event handling mechanism.
Please, anybody can help me?!
Thanks in advance!

OK. First of all, navigate to the top right hand corner of this web page. Do you see the text highlighted in red? That says .Net Framework and not Microsoft Office. You can probably guess where I'm going with this.

Hello All,
I have a client app which is in .NET 1.0 and i have to work on a webservice, i was
wondering if i can write the webservice in 2.0. In this case, will the WSE 3.0 for the
webservice and WSE 2.0 for the client app in .NET 1.0 still work. Or it won't.
Help Me !!

I'm writing a database class , I need to use a table variable from within .Net (C#), but it always gives an SQLException saying "Must declare the table variable '@Par1'."
1. I declared an SQLParameter object
2. I added the object to the 'Parameters' collection of the command
How can I solve this

What's the 'Exit For' equivalent in C#?

Most times when you use this it indicates that you have used the wrong construct. If you are issuing a break then this shows that you have reached a terminating condition.
If you need to drop out of a loop early, this would indicate that you should be using something like a while loop instead. See the following:
for (int i = 0; i < 10 ; i++)
{
if (i == 2) break;
}
Contrast this with:
int i = 0;
while (i++ != 2)
{
}

Or a different for expression
Node n = null;
NodeList list = doc.selectNodes("*");
for(int j=0, null == n && j < list.Length, j++)
{
if( ???)
n = list[j];
}

Ya, Ya, we all know the theory; but break is more handier

Handy doesn't make it right. Just lazy. If you take shortcuts here, where else do you take shortcuts? Whenever I see something like this, it sets the alarm bells ringing that there are problems with the design.

And if it's due to an exceptional state, it may be more expressive. But certainly use it with caution.

Hi guys,
Does anyone know how to deploy the MMC Snapin project ?

In my application, I have a DataGrid that is used to display search results from a query into a Firebird SQL database. The DataGrid is not directly connected to the DB, but instead I perform my query and store the results in a std::vector, perform some more work on it, then copy the final results into an ArrayList that the DataGrid is connected to.
So, when I do a search, it goes like this:
search_results_list->Clear();
tr = db_conn->BeginTransaction();
typedef vector<int>::const_iterator CIter;
for (CIter it = run_ids.begin(); it != run_ids.end(); ++it) {
search_results_list->Add(disp);
}
tr->Commit();
datagrid_search_results->DataSource = 0;
datagrid_search_results->DataSource = search_results_list;This works fine the first time, however I am having the following problem. If I click on a row, then subsequently perform another search that makes the row disappear, I get an IndexOutOfRange exception:
************** Exception Text **************
System.IndexOutOfRangeException: Index was outside the bounds of the array.
at System.Windows.Forms.DataGrid.Edit(String instantText)
at System.Windows.Forms.DataGrid.Edit()
at System.Windows.Forms.DataGrid.OnEnter(EventArgs e)
at System.Windows.Forms.Control.NotifyEnter()
at System.Windows.Forms.ContainerControl.UpdateFocusedControl()
However, my DataGrid has set the ReadOnly property to true. In my other DataGrid that is used for a different purpose, I was able to solve it by setting the CurrentSelectedRow property to 0 before removing the elements, but this does not work in this situation.
I am not sure if it is related to this, but the only event I am handling for this DataGrid is the MouseUp event, in order to get it to select the entire row when a cell is clicked:
System::Void datagrid_MouseUp(System::Object* sender, System::Windows::Forms::MouseEventArgs* e)
{
using System::Drawing::Point;
using System::Windows::Forms::DataGrid;
using System::Windows::Forms::DataGridCell;
Point pt = Point(e->X, e->Y);
DataGrid* datagrid = __try_cast<DataGrid*>(sender);
DataGrid::HitTestInfo* hti = datagrid->HitTest(pt);
if (hti->Type == DataGrid::HitTestType::Cell) {
datagrid->CurrentCell = DataGridCell(hti->Row, hti->Column);
datagrid->Select(hti->Row);
}
}
