Hi,
I have loaded a dataset with a table that contains 1000 records. so far so good.
When loaded i assign my Datagridview.Datasource event with the table, but this takes 4 seconds before i actualy see the records in my grid.
DgvCardHolders.DataSource = DsCardHolders.Tables[0];
Does someone have an idea how to show the progress of this load ?
i suppose the datagridview is copying the data from the datatable.
Thx
Kurt

Okay,
here i am again....
2 posibilities...
THE PROBLEM :
The property AutosizecolumnsMode was set to Allcells and that's whats making it slow.. so i set it to Alldisplayedcells and guess, no performance problem at all.... over 3000 records in no time on screen.. (so don't tell me delphi is faster now...no way.. just do it the right way.)
STILL WANTS A PROGRESS BAR :
If u still want to use AllCells and show a progress bar a solution is using virtualmode. Switch the property on and use the cellvalueneeded event to fill in the grid values.. in this event you can calculate the progress using the e.index and the row.count and show it on screen while loading. Don't use the Datasource property in this case.

Hello, I have a control, that creates a dialog using ShowDialog() method of a Form class. The problem is that sometimes it happens, that another application shows instead of the created dialog. I have tried passing null as an active window should be used. Tried passing the control, that creates the dialog, but no better, the window dissappears. Now I'm just experimenting with BringToFront(), Activate(), but no luck.
Any help would be appreciated, thanks a lot for your time ...

Maybe settings your own application topmost at that moment ???
your application and your dialog will remain on top of all other windows..
otherwise search for main windowhandles of other apps and hide them by a windowsmessage, but thats a lot of work i guess...

Hi
I have written an application in which on left side there are oulook style menu.When i click anyone from that menu a new child form open in panel control of parent form.
My problem is that this child form is not getting focus .i HAVE ALSO TRIED .FOCUS AND .SELECT methods.
if i donot add this child form in panel control then form gets focus but on maximizing child form it also covers the area of left created menus.
So how i can get focus on child form in panel control ? or how i restrict child form not extend from specified left position on maximization.
I am using Visual Studio 2005 c# windows form

Yes i tried this one also but child form not getting focus in panel

Also note that if there is text box on child form and in this scnerio if you click text box you can type text in it but cannot select the text in textbox by simply mouse selection(draging mouse).

Into AssemblyInfo.cs ( or elsewhere put this piece of code ).
[assembly: ComVisible(true)]<br />
<br />
[assembly: Guid("b8e616b6-9213-4103-af65-8965422566b3")]

this is already done, but still isn't working

Are you sure, the "ComVisible" attribute are set on "true"? Default value is "false".
Maybe, this KB will help you: http://support.microsoft.com/?scid=kb%3Ben-us%3B249873&x=11&y=9

This is the code:
using System;
using System.Collections.Generic;
using System.Text;
using System.Management;
using System.Runtime.InteropServices;
namespace register
{
public interface reg_inter
{
string procId();
}
[ComVisible(true)]
public class reg:reg_inter
{
public reg()
{
}
public string procId()
{
ManagementObjectSearcher search =
new ManagementObjectSearcher("select * from win32_processor");
foreach (ManagementObject wmi in search.Get())
{
PropertyDataCollection prC = wmi.Properties;
foreach (PropertyData pr in prC)
{
if (pr.Name == "ProcessorId")
{
return pr.Value.ToString();
}
}
}
return "0";
}
}
}
and this is assemblyinfo.cs:
.
.
.
// Setting ComVisible to false makes the types in this assembly not visible
// to COM components. If you need to access a type in this assembly from
// COM, set the ComVisible attribute to true on that type.
[assembly: ComVisible(true)]
// The following GUID is for the ID of the typelib if this project is exposed to COM
[assembly: Guid("3ea648c1-75cf-4d96-9978-d615378e027c")]
// Version information for an assembly consists of the following four values:
//
// Major Version
// Minor Version
// Build Number
// Revision
//
// You can specify all the values or you can default the Revision and Build Numbers
// by using the '*' as shown below:
[assembly: AssemblyVersion("1.0.0.0")]
[assembly: AssemblyFileVersion("1.0.0.0")]
Where am I wrong?

this is a program i created adding a record in the database but their is no error but an exception, saying " DB2OLEDB is not existing in the local machine."

The error message (incorrectly copied as it is) suggests the connection in the source of the problem. Have you installed DB2 on your local machine?

How to create a simple alarm application in C#..

Take your problem, then break it in to smaller parts then implement the smaller parts. If the smaller parts are still too big then break it down further until you get to a point where you can create a "simple alarm application".
Now, we can help on specific elements of your application, but we cannot help with a whole application in a forum post.
Also, what do you mean by "a simple alarm"?
The following code could be perceived to be "a simple alarm":
Thread.Sleep(60000);
Console.WriteLine("Ding! Ding! Ding! Ding!");

Okay - then break the problem down into smaller parts.
Inputs: current time, alarm time
Outputs: At specified time "ring an alarm"
* The current time can be got from DateTime.Now
* The alarm time will have to be got from somewhere: Where? User input, config file, database, somewhere on the web??
* What do you mean by "ring an alarm"?

Hi all,
Does anyone know how to import online published Schema in to another schema in Biztalk 2006?
Thanks

Well, you could use a string builder to iterate over the second group of strings and build it into a single string. There's no automatic way to do it, you need to do it yourself.

Is there a component/addin for VS that provides incremental searching/filtering of components in ToolBox.
For example I'm designing a form and need to place a button control.
I would then type letters (b, u, t, t, ... ) inside search/filter box and all component classes matching entered characters would be filtered inside ToolBox or displayed within a DropDown window.
Thanks.

Hi, i've got a problem when using the localization possibilities of .NET.
I'm using sharpDevelop2 and i created two language files (en-US and fr-FR) to match the two languages. When i compile the soft, it work whell but the dll files created from the resx files are in two folders named fr-FR and en-US directly on the program root.
I'm searching for a way to create a global 'lang' folder in whitch i will put the languages folder.
I tried to put the resx files in a 'lang' folder created in my solution but the compilation faild because the resx files are dependent of the MainForm.cs and in this case it does not find this file.
Is there any way to do that in sharpdevelop ? If yes could you explain ?
or sould i use VS ?
I hope it's clear, thank for help.

AFAIK you cannot do what you want to (no matter which IDE you use) since the framework has a fix algorithm to look for those satellite assemblies.
