Hi. In my windows form, there is a button control.

When i click on it, just removing the controls from window and adding progressbar dynamically to the window. It working fine and progress bar appearing nice.

At the same time, i am adding Label control to form at runtime only. But it appearing last(i.e after completion of process of progressbar).
Why it wont appear on window first...

in code i added label to form first and then progressbar

can any one give idea reg this.........

Windows execute the code in message queue.

So after the label display you have to use

Application.DoEvents();

Hope this help.

Hi!
Simply take a look at the Label.Font property. That wasn't hard, was it?

Hi all,

In my project i am reading a binary file of 81MB size and this information need to be inserted in to different tables of database.
The binary file is having several sections, contains some millions of records. while reading the binray information i am conveting the bytes in to c# datatypes and saving in arraylist, finally i am inserting in to the database Which is taking huge amount of time.
to insert this 81 MB size file in to database my application is taking 30 min.
Can any one suggest me how can i optimize the performance?

Thanks in advance

Hard to say.
There are a lot of ways to boost performance.
- Is the algorithm optimized? Are your for loops ok? (you don't perform actions in for loops that could be done outside eg.)
- Do you have GUI updates like a progress bar or something?
- Try an Ngen compilation, it might help (See MSDN)
- Can you use threads? eg Read in a block of bytes and while the DB updates, Read the next block at the same time etc...
- Did you use optimezed objects? (StringBuilder for string concatination eg.)

Hope this helps...

Hi,

You are use following tips/suggestions/whatever Smile | :)

1. Dont use INSERT when "LOADING" the data, use BULK INSERT
2. You can convert the data into c# format, and dump it as required in some temporary file, and bulk insert data using that file. If you are good at threading, you can boost the performance considerably.
3. If you are comfortable with Dynamic SQL, use it after converting data to c# datatypes.

And if you are good in threading and dynamic SQL then you can have a boost in performance as "complete loading of a 45 GigaBytes of data to 12 tables in 1.5 hours". That is what i experienced once!

Hope that much performance is enough for now and you find it useful! Smile | :)

Combox problem urgent!!!

I'm Having a combobox which having items from itemtable. When table is empty then I have to show "No items" and if items are their in table then I have to show the item. So I fill datatable like

if (dataTableItems.Rows.Count >= 1)
{
cmbItem.Items.Clear();
cmbItem.DataSource = dataTableItems;
cmbItem.DisplayMember = dataTableItems.Columns["ItemName"].ColumnName;
}
else
{
cmbItem.Items.Clear();
cmbItem.Items.Add("No items");
cmbItem.Text = "No items";
}

This is working fine on form's load event.
But I have a button that will get items from other datatsource and fill the item tables. On click of the button I again fill the datatable and same code

if (dataTableItems.Rows.Count >= 1)
{
cmbItem.Items.Clear();
cmbItem.DataSource = dataTableItems;
cmbItem.DisplayMember = dataTableItems.Columns["ItemName"].ColumnName;
}
else
{
cmbItem.Items.Clear(); <-- ERROR COME HERE
cmbItem.Items.Add("No items");
cmbItem.Text = "No items";
}

But it will give error "Items collection cannot be modified when the DataSource property is set."

please help

First you should set the combobox's datasource to nothing:

cmbItem.DataSource = string.Empty;

Hope it helps.

I will use Google before asking dumb questions

I tried a lot and finally write this

cmbItem.DataSource = null;

This is working fine.

Will it create problem in the future...? Please reply...:->

Dear Christian Graus your suggestion needed this time... Confused | :confused:

Wow. It's urgent with three exclamations. That makes it much more likely to get answered quickly. Wait, if I post urgent and put four exclamations in, does this mean my question will get answered before yours?

Now, please post questions with meaningful titles and respect the fact that these boards are looked after by volunteers who will get to your problem when they are ready. If your problem really is that urgent, then you should probably seek an answer in an area where people get paid to help.

Deja View - the feeling that you've seen this post before.
