This last information that you provided suddenly makes the error very obvious. It has nothing at all to do with event handling.
You are opening files using a relative path, that means that you are using the current working directory as a starting point. The file selector dialog also uses the current working directory, and changes it as you navigate through the folders. That means that your code is trying to open the image files from a different starting point, where the images doesn't exist.
The quick solution would be to store the value of the current directory when starting the application, so that you could use that value for locating the images. But I don't understand why you create a new Image object from a file every time the mouse pointer enters or leaves the control. You'd be better off by loading the images at startup, so that you can use the same Image objects over and over.

Hi!
I want to disable or hide the dropdown list in comobox. Can I do this and HOW?
Set DropDownStyle to Simple is not ok for me, because I want to allow AutoComplete mode. When I select value from suggest list of autocomplete mode selecting value doesn't work. Combobox has binding to dataset.
If DropDownStype is not set to Simple selecting value works fine, but I must hide dropdown list from user.
Thanks

I am working on a C# project. I have already completed the project but now I am looking for something like:
1.. Customer start the software and he will be asked to register on my site which uses a optin newsletter script. It will then store the member information into the mysql db.
2.. My software will then check if the member is registered.. if so it will then store his computer hardware id next to his email address in the database.
3.. Everytime the software will check the user details. this way he cannot share his copy of the software with the other.
4.. Also another point is if this customer is unsubscribed from my list he wont be able to use my software.

Hi all,
I have created an application in C#.
The application will be distributed to many users.
Some new features will be added later to the app.
Now i want to create a functionality that will be like
Whenever the app starts, it will first check on the server for
files with new version and should replace the existing with new version files. I want the app to automatically download the new dll's and replace the existing ones with these new ones.
Any reference or link or sample code in this regard will be appreciated.
Thanks & Regards,
Pramod

you can use setup factory setup 7.0 {Search it fro google} for your product! their you will find the auto update functionality inside which conncet your product to server....
|
|
|
|

That seems to be some product.
I don't have to use external products.
Is there any feature in .Net for this.
Or some customized code?
Thanks & Regards,
Pramod

If the app is 2.0 based you can use Click-Once. Otherwise look at the Updater Application Block from Microsoft's Patterns & Practices group.
