dsMI is a DataSet and I did create the DataSet using
DataSet_MI[][] dsMI = new DataSet_MI[10][1].
Everything was done exactly as with dsI and it loaded dsI.

Vikram was right - looks like you don't initialise the object referenc - additionally you have a problem with dsMI[x][1] - you should get an ArgumentOutOfRange exception here! Watch out for the '1'.
Try using one more line:
dsMI[x][0] = new DataSet_MI();
just before the add.

Did you read my post? DataSet_MI[][] dsMI = new DataSet_MI[10][1] only creates a 2-D array of references, *all* of which are null, not a 2-D array of DataSets. You have to do
for(int i = 0; i < 10; i++)
{
for(int j = 0; j < 5; j++)
{
dsMI[i][j] = new DataSet();
}
} to get a 2-D array of DataSets. Replace 10 and 5 with your dimensions.
Cheers,
Vikram.

Hi
As a one of several projects in this semester at university i had to write socket application. So I wrote it. It works, well not flawlesly but I think not bad. In that app I'm using ZedGraph libraries to create graphs. It works of course. Ok, now is THE question: how to embed that dlls into output exe so I can use that embedded dlls as references to project to work everything right? I tried adding dll to a project and then in properties of dll file changing "Build Action" to "Embedded Resource". After building project output file was larger so i think that dlls are in exe. Unfortunately I can't in no way make a references from that files to project. Mmm, another stupid :P question: what is it for? I mean embedding something into exe when I can't use it? I've never used it so my knowledge is like "null" in that area.
Sorry for my bad English and thanks in advance for any word of help.
[EDIT]
I forgot to mention that I use VS2005. Sorry..

You can get a stream to an embedded resource, so you coulds use them for sounds or images etc.
And anyway, whats wrong with having the dll's outside the app?

Currently, this code will return immediately after the process is
started. How can I modify it so that it will not return until the
process has stopped?
using (Process process = new Process())
{
process.StartInfo.FileName = @"C:\myprocess.exe";
process.StartInfo.Arguments = String.Format("-j {0}",
path);
process.Start();
}

{<br />
[DefaultProperty("Text"), ToolboxData("<{0}:CustomDataGrid runat=server></{0}:CustomDataGrid>")]<br />
public class CustomDataGrid: DataGrid<br />
{<br />
<br />
public CustomDataGrid()<br />
{<br />
base.CopyBaseAttributes( this ); <br />
}<br />
<br />
<br />
protected override void OnItemDataBound(DataGridItemEventArgs e)<br />
{<br />
foreach( TableCell tblCell in e.Item.Cells)<br />
{<br />
tblCell.Text = tblCell.Text.Replace(">", ">").Replace("<", "<");<br />
}<br />

return dt;<br />
<br />
}<br />
<br />
You will note that the bound columns are a templates columns, the project is working properly in case of the grid columns is bound columns, but it’s not working in case of templates columns.
The second issue in the HTML design mode this error will apper
The active schema dose not support the element 'FooterStyle'
And 'asp:TemplateColumn'
And 'HeaderStyle'
And 'asp:TemplateColumn'
Etc. .
Why is the error for and why the controls dose not accepts template columns
Thanks in advance

Why would you want to do that? Anyway, I doubt that it is possible.

Without it being part of the OS, then there's no way to make an application unkillable. It might be unkillable from the user level you're at, but it will be killable at some level.
Why would you want to do this anyway?
|
|
|
|

i hear that when OS want terminate an application send a kill signal to it.
now if handle this signal in our app then can restart our application in termination time of old application time.
And now HOW TO HANDLE THIS SIGNAL ?

As far as I know... Windows will politely ask the application to close, and perhaps you can ignore that request, but if the application doesn't doesn't close in response to the request, then Windows will attempt to kill the process, and there is no way to stop that.
As for how to ignore the request, you can probably handle that in the FormClosing event handler.

hi.
I have a maskedTextBox which is going to accept date from user.
it's format is (00/00/0000) or (Short Date)
and i am using system.datetime.parse() to validate it.
by defult it accepts (mm/dd/yyyy)
how can I change it to (dd/mm/yyyy)?
Regards
|
|
|
|

Use:
DateTime result = DateTime.ParseExact(inputDateTimeAsString, "dd/MM/yyyy",
System.Globalization.CultureInfo.CurrentCultureInfo);
Hope this helps!

Hi there,
i want to set opacity of picturebox like form,
i know its a very common question, and i searched on lots of sites but didnt find any good answer
can some tell how or any article about it?
thanks

I don't think you can, I think you need to draw the image yourself and use the ImageAttributes class to set the opacity.

HI
I'm using propertygrid to display my class properties in it. My code is just Like:
public partial class AddressType
{
.......
.......
}
public partial class Person {
private AddressType homeAddressField;
public AddressType HomeAddress
{
get {
return this.homeAddressField;
}
set {
this.homeAddressField = value;
}
}
}
PropertyGrid just shows the Person Having field HomeAddress. But I can't expand HomeAddress to see AddressType (which is also a class and have actual address properties).
I used ExpandableObjectConverter just like:
[System.ComponentModel.TypeConverter(typeof(System.ComponentModel.ExpandableObjectConverter))]
public partial class AddressType
{
.......
.......
}
[System.ComponentModel.TypeConverter(typeof(System.ComponentModel.ExpandableObjectConverter))]
public partial class Person {
private AddressType homeAddressField;
[System.ComponentModel.TypeConverter(typeof(System.ComponentModel.ExpandableObjectConverter))]
public AddressType HomeAddress
{
get {
return this.homeAddressField;
}
set {
this.homeAddressField = value;
}
}
}
still It has no change......
Please help me how can I tell propertygrid to expand when one class contains another class object.

Your question is far too vague. Is there something specific you need help with?

Huh? Please rephrase your question a bit better. Makes no sense.
