My suggestion is, don't bind to the combo box. 134000 is plainly too many items for the user to look through. You will be much better off providing the user with the ability to search for an item.
Also, it's considered bad form to write "it's urgent" in message boards posts (kindly read the FAQs), as it is only urgent to you.

I'm surprised you did not get an "out of memory" error or something.
I dont think the user is going to like scrolling through soooo many records - think of a different strategy - dont use a combo box.

There's no fix for "stupid". Your best hope is that a competent programmer take over the project.

I too giggled the first time I saw this posting and now I am in a similar predicament. I have a client who has had enough of the data entry errors his staff constantly makes while entering chemical names by hand. So we have a combo box with an autofill function, so if they type 'Alc' the combobox will display all records that start with 'Alc'.
There are 3 of these combo boxes each one with over 25,000 items. The page takes 4 seconds in loading. The client is happy, I of course i'm not.

By loading a lot less data.

Try using a System.Terror to load the datas. 
OK, really bad design. You should let the user search or at least provide some sort of paging or...
- But, as a small improvement to whatever you have, you could unbind the combo,
get all the datas in a array of strings using a datareader then use the Items.AddRange();
- also wraping the whole filling of the combo in a
"comboBox1.BeginUpdate(); ... comboBox1.EndUpdate);" should help a little.
Again, bad design.
But still 45 secs seems way to much for 134000 strings/records.

Good luck

Hi,
I am currently using bing maps. There is one text box and a search button which will find the location on bing maps.
I have already done with that, it is finding the location properly, when i enter the location/address in textbox and click on the search button.But, i want to mark that location using polygon shape.
It means when i enter the address in textbox and hit the search button it will find the desired location and mark that area in polygon or circle shape.
How can i achieve that. Can any one provide me some code or some useful link which can help me out.
regards,
Pranav dave.

I friends, I made a simple program that use Drag&Drop event.
private void textBox1_DragEnter(object sender, DragEventArgs e)
{
e.Effect = DragDropEffects.Copy;
}
private void textBox1_DragDrop(object sender, DragEventArgs e)
{
String str = (String)e.Data.GetData(DataFormats.StringFormat);
textBox1.Text = str;
}
When i run the program under windows7 the Drag&Drop event doesn't function, but the same program under WindowsXP, function.
Could anyone explain why there is this problem?
Thank you.
Bye Bye

Some more detail is required.
Where are you dragging the text from?
Does the dragenter event fire?
Is the data in the e.Data.GetData?
Is there an error generated?
Have you set allowdrop on the textbox?
Have you stepped through the code to see what is not happening?

Thank you for reply.
I drug a txt file over the textbox, the allowdrop property in set.
The code is ok, becouse 10 minutes ago i tried to rum my application, with only exe file not under debug in Visual Studio, and everything is ok.
Now, why under source-code the drug&drop doesn't function but if i run the application from exe file everything is ok?
Thank you!
Bye

I'd be VERY worried about dragging a file from explorer into a text box, you are hoping  explorer behaves the same for both XP and weven. One is probably dropping the filename into the text box and the other is tyring to drop the file object into the text box.
Inspect the content of what is dropped to determine what has arrived.

Hi.
I'd like to have access to the bytecode that is currently running or about to run in order to detect certain instructions and take specific actions (depending the instructions). In short, I'd like to monitor the bytecode in order to add safety control (see DETAILS below for explanation).
Is this possible? I know there are some AOP frameworks that notify you of specific events, like an access to a field or the invocation of a method, but I'd like to skip that extra layer and just look at all the bytecode myself, throughout the entire execution of the application.
I've already looked at several AOP frameworks (although not in great detail, since they don't seem to do quite what I need) and I'm familiar with Mono.Cecil.
I appreciate alternative suggestions, but I don't want to introduce the overhead of an AOP framework when what I actually need is access to the bytecode, without all the stuff they add on top to make it more user-friendly (... admittedly very useful stuff when you don't want to go low-level).
Thanks 
DETAILS:
Basically, I have a C# application and I need to monitor the instructions it wants to run in order to detect read or write operations to fields (operations Ldfld and Stfld) and insert some instructions before the read/write takes place: I may need to acquire locks, or if that fails abort the operation. Also, I may need to update a read log (in case of a read) or write log (in case of a write).
In fact, what I'd really like to do is to replace the read/write instruction with my own custom code, but it that fails I think I could manage just inserting some instructions before and after.

Would a simple property do what you want?
Maybe even write a class to hold the affected fields.
|
|
|
|
|
I'm afraid not: I need to be able to detect accesses to any data, including fields of sealed classes which I cannot redefine as properties.
As for your second suggestion, if the field is of a sealed class I won't be able to write a wrapper that extends it. For example if I have:
class SomeClass {
SomeSealedClass fieldIWantToProtect;
}
sealed class SomeSealedClass {
...
}
I cannot write a class:
class SomeSealedClassWrapper : SomeSealedClass {
}
Thanks for your answer.
