First i tried to do this with following code: System.Data.DataTable.Select(System.Data.DataColumn.ColumnName + " = NULL");
but this didn't work!
so how should i modify my syntax to get the reult i want to have?
|
|
|
|
|
Try " is null" instead.
---
b { font-weight: normal; }
|

|
|
yep this is the solution!

I believe this should do the trick, just use the Forms Resize event since it is called when the Form is minimised.
private void Form1_Resize(object sender, System.EventArgs e)
{
if (this.WindowState == FormWindowState.Minimized)
{
this.Visible = false;
notifyIcon1.Visible = true;
}
}
|
|
|
|
|
It just dont cancel the minimize event......
Im kinda looking for a way to stop the event because it still minimizes before hiding.....

Copy the following method into your form.
protected override void WndProc(ref Message m)
{
if (m.Msg == 0x0112)
if (((int)m.WParam & 0xFFF0) == 0xF020)
return;
base.WndProc(ref m);
}

Hi everyone,
I've been having a problem when using ShowDialog (more that it doesn't do what I want it to do  )
I've got a main form, from which I create a child form which I want to always be available (I use Form.Show() to show it).
Later on, the main form will then show dialog forms (using Form.ShowDialog()). The problem is that doing this causes the child form (which I want to always be available) to be blocked along with the main form, so the user can only use the new dialog form.
Is there a simple way around this? I'd prefer not to have to change using ShowDialog, because I do this all over the place. Can I just change what I do with the child form I want to always be available?
Here's a quick example piece of code which has the effect I'm trying to explain:
private void MainForm_Shown(object sender, EventArgs e)<br />
{<br />
Form alwaysAvailableChild = new Form();<br />
alwaysAvailableChild.Text = "Should be Always Available";<br />
alwaysAvailableChild.Show();<br />
<br />
Form dialog = new Form();<br />
dialog.Text = "Dialog";<br />
dialog.ShowDialog();<br />
}
Cheers in advance.

When you show a form with ShowDialog() you will not be able to use other forms, because the form you just showed is showed like a dialog....
Which means that other forms not will be available before the dialog is closed again...
So if you just use Show() it should not give any problems....
Hope it solved your problem..

I realise that this is an easy option to solve the problem (although I'd have to manually disable the main form myself)... but I was more wondering if there was a way to have a completely "seperate" window from the rest of the application, so that when the main window shows a dialog, my "seperate" window will be unaffected.
The reason I'm asking is that I've got my application which shows dialogs here, there, and everywhere, and now I want to add a, sort of, help window, which is always available (preferably without moving it into a seperate application).

I think maybe you should run your help window in a seperate thread....
Hope that solved it

Try using WMI to get these values. You could combine them to create a unique ID too. Microsoft has a WMI generator tool that will help with the code, you can get it here: http://www.microsoft.com/downloads/details.aspx?familyid=2CC30A64-EA15-4661-8DA4-55BBC145C30E&displaylang=en

Your question is a little unclear.
If you mean, change either the form background colour / label font-colour when an item is selected in a dropdownlist, the you simply need to handle one of the selection changed events (SelectedIndexChanged, SelectedValueChanged or SelectionChangeCommitted). In the event handler, you can then call a method to change the colour of the target control by setting the value of the approriate property.

how could i get that in which drive windows is installed?!
|
|
|
|
|
System.Environment.SystemDirectory returns the path to the System directory... you could just get the first character.
|
|
|
|
|
You can retrieve the path of the system directory using the Environment.SystemDirectory property and extract drive information from it:
string windowsDrive = Path.GetPathRoot(Environment.SystemDirectory);

Dear all,
I want to calculate the execution time of a certain piece of code. I noticed that the min. value I can get is the tick which is equivalent to 100 nanoseconds. I want to know what shall I do if the code takes less 100 nanoseconds, especially on fast computers? I tried to use DateTime class and TimeSpan class but they were of no use. Any help
Regards

If you're using .Net 2.0, there is a new class:
System.Diagnostics.Stopwatch

That still has a resolution of at least 10-15 milliseconds.

From MSDN:
The Stopwatch measures elapsed time by counting timer ticks in the underlying timer mechanism. If the installed hardware and operating system support a high-resolution performance counter, then the Stopwatch class uses that counter to measure elapsed time. Otherwise, the Stopwatch class uses the system timer to measure elapsed time. Use the Frequency and IsHighResolution fields to determine the precision and resolution of the Stopwatch timing implementation.
The resolution is 0.5 nanoseconds on my 2GHz system, although the overhead of calling Start and Stop seems to be about 10 microseconds.

Be excellent to each other
