There is most likely your problem.
Unless you have multiple CPUs or a multiple core CPU, only one thread at a time can run. Your thread that updates the progbress bar will update the progress bar once, then it will wait it's entire time slot for another change that will not happen, as it's blocking the thread that would do the change.
When there is nothing for the thread to do, you should do a Thread.Sleep(0) to give up the rest of the time slot so that another thead can use the CPU time.
Despite everything, the person most likely to be fooling you next is yourself.

That helped a ton. I moved the wait up to 1000 milliseconds and it was about the same. My old SQL Server must be the slow down, it seems like it goes fast for a while and then really bogs down, sounds like a SQL I/O issue.
Thanks.

Hi,
My form contains several controls like textbox, labels, buttons, panels etc..
To access these controls I used the following for loop.
foreach (Control ctrl in this.Controls)
{
}
Panel contains 36 checkbox controls. I'm unable to get checkbox controls in the for loop becoz those are in panel..
How to access and modify the properties of checkbox controls, which are in Panel. Thanks in advance..

The loop you are running will only get the controls in whatever Container this is (Usually a form, and looks like it is in your case). Run that same loop on the panel and you will get all the controls inside of it.

Thanks for your prompt reply. Can you explain what does the following sentence mean?

Reread my post, it got cut up all weird for some reason, I fixed it.
That is my signature. It means the only way to make a Mac is to drop it (preferably off a very tall building).

instead of this.Controls, loop through the controls in panel.Controls.
Or better yet, if they are dynamically created by you, when putting the checkbox in the panel, put them in a List/ArrayList so that they are easier to be referenced.

I am using the bitblt() function for printing a bitmap with c#. But the printing quality I am getting in this case is not satisfactory at all. Actually, the type of bitmaps that the 'BitBlt()' function requires are normally in the format of the display driver rather than the printer driver. So I am thinking of using a DIB rather than DDB and for doing this may be StretchDIBits() function can be used.
Please help me with some code sample on how to use the StretchDIBits() function in C#
Thanks in advance

You can use StretchDIBits if you want, using P/invoke. However, did you set the stretch blit mode of the graphics object you're using and see if that helped ?

Is it possible to backup and restore a MySql Database using C#?
How? Any suggestions?
|
|
|
|
|
Yes, it's possible: Get all tables, foreach table, get all columns and then create the script that will add this table into a Mysql database
|
|
|
|
|
This is somewhat confusing. Could you give me more specifics on what you're suggesting? Are you saying that I backup the database by placing it on another database?
I was thinking more around the grounds of backing up my database on a *.sql file and restoring it from a *.sql file using C#.
|
|
|
|
|
No, I was saying that you should create the sql script by yourself analyzing the structure of the current database

Ohhh... Hmm... Interesting... Thanks.

Hi,
does anyone knows how to ge the size (area value) of an inregular shape in a bitmap image.
i have a bitmap image with a black background and the shape is all in white, i wonna get the size of the shape and say yes if the shape has rugged edges or no if its more like a circle.
I appreciate any help.

You could look at my image processing articles for info on direct pixel access, then you could walk the image and see if it has straight edges.

Now, I'm very curious, did you actually find that function name (sig) in a real life application, or it's just a sig?

It was a method in code someone posted here asking for help.

string hex3 = "025";
int code = Convert.ToInt32(hex,16);
int code1 = Convert.ToInt32(hex1,16);
int code2 = Convert.ToInt32(hex2,16);
int code3 = Convert.ToInt32(hex3, 16);
richTextBox1.Text = Encoding.Default.GetString(new byte[] {(byte)code,(byte)code1,(byte)code2,(byte)code3});
Now i need arrange all the ascii char in correct position.I hd tried in many ways,but still got errors.pls help me.

Hi guys,
I feel like stupid, anyway. I have a very common question and please no utfg answers, I've done that.
I'm no able to create a control that can accept dragged items from other windows (e.g. files dragged from windows explorer or icons from desktop). I'm using .NET 2.0 and Vista. Is it just something small that I'm doing wrong?
here is what I'm doing.
- create custom control derived from System.Windows.Control class
- make sure the AllowDrop property is set to true
- override OnDragEnter, OnDragDrop, OnDragOver etc...
my problem is that those events OnDrag... never get raised when dragging anything above my application window/control.

I thought you need to also specify in code what file types you accept being dragged ?

Hi,
i'm trying to filter data withe The Binding Source
the thing is that i have a cloumn that is Set as
DateTime Type.
Now i'd like to Filter Monthly Like : "04/2008"
the Thing is that i've got a DateTimePicker that is in the same Format but i don't know what to put in the Filter
i Started with :
BS_WorkingHours.Filter = "(Date > '" + MinDate + "') AND (Date < '" + MaxDate + "')";
Where MinDate Day is Set To "01" + Current Month and Year And MaxDate is Set To "31" + Current Month and Year
they are Both strings
it Does not Accpet String for Compare so i'll need to Put
The DateTime Object itsef, but the DateTimePicker Value Includs
The Day Which in this case i do not need
AnyOne, THANKS 
Have Fun
Never forget it

Of course it does. You are assigning a string to the Filter property. A string can not contain anything but characters.
You can create DateTime values from the year and month values:
DateTime minDate = new DateTime(selectedDate.Year, selectedDate.Month, 1);
Using 31 for date doesn't work well, as all months doesn't have 31 days. Add a month to the startdate, then subtract one day to get to the last day of the month:
DateTime maxDate = minDate.AddMonths(1).AddDays(-1);
Now you can format the dates into strings and concatenate into the filter expression.
Despite everything, the person most likely to be fooling you next is yourself.
