Hi,
How to read datagrid column’s headertext?
I am creating datagrid columns dynamically. I am specifying the datagrid’s headertext in th aql query only, like, “SELECT empname ‘Employee Name’, desg ‘Designation’ FROM emp”. In this case *Employee Name* and *Designation* will be datagrid column’s header.
How to get these header texts?
Thanks in advance…

You have an executable named shutdown.exe in windows, you can run it to restart the computer.
The command line is: shutdown -t 0 -r -f
I know the Windows 2003 and Windows XP provide this executable.
Good luck,

Hi, I am creating my own datagrid control, as I needed the vertical scrollbar to be thicker than standard (because this dg is targeting touch screen users). Anyway, I am overriding WndProc, seen in the code below:
protected override void WndProc(ref Message m)
{
try
{
if (m.LParam == this.VertScrollBar.Handle)
{
object result = m.GetLParam();
}
}
catch (Exception ex)
{
string test = ex.ToString();
}
base.WndProc (ref m);
}
My problem is that GetLParam takes a System.Type cls parameter, and I have no idea what I should be putting in there. Please let me know how to fix this if you know what should go there. Thanks in advance.

Hi!!
I am a bit confused with regards to constant variables. I have a class called something like MYGlobals (for example). In this class I want to define global variables used throughout my web project. I think there is 2 ways of doing this, or am I mistaken. For example, are the following 2 declarations basically the same thing?
public static const int C1 = 5;
public static readonly int C1 = 5;
What is the correct way to define constants?
Please help and advise!!
I appreciate your help.
Regards,

A constant can not be static.
public const int C1 = 5;
Be ware that the value is compiled into the code wherever you use the constant. If you change the constant you have to make sure that all code using it is recompiled. This is not a problem within a single project of course.
public static readonly int C1 = 5;
When the class is loaded the integer is created and initialized. (The initialization is done in the static constructor of the class.) The value is not compiled into the code, but referenced whenever it's used.

Can anyone explain me about the differences between HashTable and ArrayList
|
|
|
|
|
In an ArrayList you get a dynamic list of object that are accessable by their index in the list.
A HashTable allows you to store an arbitrary key for each object. If you use an integer you increment after each add to the HashTable , then you'll get approximately what an ArrayList can do, but usually the keys are chosen differently and more appropriate to the way you want to access the HashTable entries.
For example, you could add objects to your HashTable with an object ID as key.
That way you can easily get the object for a given ID without having to run through the ArrayList and search for the object with the matching ID.
Regards,
mav

Hello,
This week I was given something cool to do. Take a Tablet and Ink enable our Tiff viewing app. Sounded easy. This is what I have:
1 Microsoft.Ink.InkPicture inkPic, that I’m loading with inkPic.image = SomeTiffFromFile
I’m not bothered by scaling problems yet.
This control captures Ink and saves it as Strokes and it works wonderfully. I’m trying to save the Ink into the Tiff.
This is what I have tried:
First I bring the Tiff into Drawing.Bitmap bmp = Image.FromFile(“filename”) (this is the same file I use as the inkPic.Image) Then I make a new Graphic from the Bitmap. Since Ink is made of Points (Ink.Strokes[Foreach].GetPoints(Foreach)) I figured I could do this
Graphics g = Graphics.FromImage(bmp);
for (int i=0; i{
p = this.inkPicture1.Ink.Strokes[i].GetPoints();
foreach (Point x in p)
{
g.DrawLine(pen, x, x);
}
}
bmp.Save(nameBase+".tif", System.Drawing.Imaging.ImageFormat.Tiff);
But that isn’t working.
I took the tmplate for this project from the PaperForm that came with the Tablet SDK. However it doesn’t save any thing and all the SDK examples that save save the Ink speratly from any image using Ink.ExtendedProperties.Add(guidImage, Gif);
I need the Ink burnt into the Tiff as one document.
Out prototype used a brush instead of Ink and it didn’t seem to work well. Too choppy. The InkPicture feels a lot nicer to use.
Ps. Does any one know a good comprehensive book about handling Tiff with GDI+
Thank you for any feedback

I was wondering if anyone had a chance to use DockPanel Suite for dockable windows from sourceForge. I have a question about the modal feature. The problem is with a floating form (not docked). When this form throws a message box, the message box is not modal as it should be. When the form is docked, the message box displayed is modal. Is this by design or am I doing something wrong?
Thank you in advance

Hi,
I have to perform a specific action using several windows like hundreds of times. I could speed it up if could do this automatically:
When an Internet Explorer window is open, look for a specific regular expression match on the displayed content. If it is found, copy it to the clipboard and close the window.
The tool should not be triggered automatically and check on every window. It can, but it doesn't have to. I can as well focus the specific IE window and start it using a shortcut...
Just don't have a clue on what is the best way to start. Should i use win32 api calls, and which or is there a better C# (.NET) way to do it?
Thanx

Hello all,
I have searched alot on "Windows API hooking". Most of the articles that I found are either theoretical or out-dated (or ASM or C++/C code). What I want to do is to hook the winsock32.dll for my *almost-firewall*. Any hint where I can learn about this?
Many thanks in advance,
tmp0

Well, if you're trying to this from entirely from C#, then you're out of luck as it isn't possible. You're going to need something that will give you a non-managed interface for you to call into. You could look into madshi's madCodeHook at http://www.madshi.net/. I've used it before and it works, but you have to know what you're doing.

Hello Joel,
I did find many products for *ready-to-use* API hook SDK. But I wanted to do it my self and not rely on someone's else's work.
It doesn't have to be entirely in C#.
Many thanks for your response,

I have a set of points in a space (in OpelGL) and a DataGrid, in which I keep coordinates of these points. I would like to highlight a specific point in this space, whenever user gets his mouse over the row, that represents coordinates of exactly this point. How to capture this event in DataGrid (so the event that mouse is over eg. 4th row of the DataGrid)
2nd question - how to highlight a specific row in DataGrid?
thank you for your help and time
