Hi all,
I have write a program for showing added records, couter. but it does not working/showing during the for loop execution. after stoped loop it will show. but i want to show it as continue (1,2,3 ... 50000).
for (intCounter = 1; intCounter;= 50000; intCounter++)<br />
{<br />
lblShowCount.Text = intCounter.ToString();<br />
<br />
oEmployee.AddRecord();<br />
}
Please guide me what would be the better approch for showing continue Counter during the loop execution

this will do....
for (intCounter = 1; intCounter;= 50000; intCounter++)<br />
{<br />
lblShowCount.Text = intCounter.ToString();<br />
Application.DoEvents();<br />
oEmployee.AddRecord();<br />
}

Calling Application.DoEvents is the easy way to fix this. Putting the AddRecord call in another thread, and having the end of the thread call fire a new one, is the better way.

I thought doing 'Application.DoEvents();' was bad practice?

hey guys
ive got a memory leak in a server app im working on...
in a nutshell its a chat server, clients log on and the server relays a message send by one client to all the other clients
when i close it the form goes away but the process is still running
is there any way for me to find out which objects or classes are still running in the background?
how do you guys figure out where a leak lies?
im using visual studio 2008
thanx

Probably some threads are running. If you create a new thread, set property myThread.IsBackground=true.
That means, if you close your process, all threads will be closed also.

You want to use Clr Profiler. These[^] links should help.

how do you guys figure out where a leak lies?
In this case (since it seems you've just left a thread running), it's quite easy. First, it's good practice to name your threads when you start them:
Thread t;<br />
t.Name = "mythread"
Now, when you close your program and expect it to exit, but it doesn't, you can use the "break all" option from the debug menu, pausing all threads. Select the threads window from debug->windows to see all running threads and - assuming you named your threads - you can see the thread causing your problem. In most cases you can even double click the thread and see what code it was executing when you pressed "break all".
Standards are great! Everybody should have one!

Hi, I have this one problem.
I have a ms acces file .mdb. I'd like to read from that file using SQL commands.
I can fill DataSet with returned data from SQL command, but I can't do anything with that strange DataSet.
This is the code I have now. Well it works. but it's completly unusable.
string adres = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=bazz.mdb";<br />
OleDbConnection polaczenie = new OleDbConnection(adres);<br />
polaczenie.Open();<br />
<br />
string pytanie = "SELECT * FROM Tabela1";<br />
OleDbCommand wyslij = new OleDbCommand(pytanie, polaczenie);<br />
OleDbDataAdapter adapter = new OleDbDataAdapter(wyslij);<br />
DataSet dane = new DataSet();<br />
adapter.Fill(dane);<br />
<br />
<br />
label1.Text = dane.Tables[0].Columns.Count.ToString();<br />
label2.Text = dane.Tables[0].Rows[0].Table.Columns[3].ToString();<br />
polaczenie.Close();
How to work on that thing? How to explore DataSet? Isn't there any kind of reader like SQLDataReder for acces files?
Thanks in advance for any answer or links to tutorials where I can find some info
Best regards
|

A DataSet contains DataTables, which contain Columns and Rows.

Use an OleDbDataReader if that's what you want.

Hi,
There is direct way to print the contents of a RichTextBox in .Net. However, there is a way to get this done. Please go through the following article posted at Microsoft's website:
http://support.microsoft.com/kb/812425[^]
This article provides step-step implementation of printing the contents of a RichTextBox.
I hope this helps .

hi friends.
All of you have seen that tab in visual studio where solution explorer, toolbox, properties is written and when user move mouse over them, one panel come out where we have some data in treeview. Hope you got the scenario.
Now i too have 2 treeview in my window application.
and i want the same interface which visual studio provide in my application.
is there any inbuilt control provide by framework.
Hope you understand what i want.
Thanks lot friends.

You are looking for a tab control with auto hide and run time docking feature. Unfortunately currently any window control does not provide you similar features.
However there are many third party tab controls which come with these features. You may use google to find them.

Take a look at the Dockpanel Suite[^] on SourceForge. It's quite good. If your application is meant for the average user though (as opposed to the average developer) I would reconsider using these kinds of controls, as they often find the VS way of doing things overly complex.

Thank You.

You will need to install, installshield setup creator software. One you are done with this, you may use install shield to create a setup for it.
You may also check its help file for getting steps to use it.

Hello Sir/Mam,
I want to synchronise 2 images.when I perform operations like zooming ,panning on one image the other should get effected automatically. I have performed this in the following way......
In the mouse wheel event i am performing zooming. and mouse down and mousemove events i am performing panning.I am not using any scroll bars...
The problem is when i'm performing zooming(i.e., when i'm rotating the mouse wheel fastly then the images are not synchronised properly..I should overcome this problem.. pls help me..
Thanks,
rekha.

Well, I'd love to help, but seeing as you didn't post any code, I have no idea what you did wrong.
You should be storing the zoom for both images in one variable, so it's in sync
