This is just what I'm looking for, I think I'm going for the ReaderWriterLockSlim as the dictionary will be used mostly for reading with occasional writes.
Thanks a million!

I'm using the .net Settings feature to keep track of user preferences for a click once app.
Problem is that every time I release a update, the settings all reset to default.
(This is because the settings are being stored in the users documents and settings folder under a folder that includes the version number, so when I release and update and increase the version number, the app can no longer find the file to load the settings from, so goes back to the default)
Is there a way to cause it to ignore version numbers and just save the settings in a non version specific folder?
Cheers.

The best way is to write specific code to seek the previous versions configuration and import it into the new version. This is because future versions, could in theory, break and not rely on the same configuration information.
Otherwise, just use non-api methods to access folders and pick a good place ... like create a common in your company folder created for the user for the version information.

Thanks Ennis

Tricky because the folder the config file is stored in looks like some form of hash combined with part of the assembly name. I don't know the rules for generating this path.

Thats fair enough, I can kind of understand why MS didn't just make it work. Weirdly though, I wrote quick test app to make sure it wasn't something wrong with my code, and it behaved as I described (settings reset after version increase). But then I went back to it after writing the post, and now it works fine  settings are maintained between version increases exactly as I want them to be.

Yeah, I thought about doing this, but it feels like going back to the old .ini file way of doing things. I thought 'settings' was supposed to remove the need for doing messy things like this.

You should be able to use the Upgrade() method available with the built-in settings to "upgrade" the user.config created with your new revision with the settings from your old revision. You don't have to worry about where the old user.config is located.
I typically create an 'ApplicationVersion' setting which I compare to Application.ProductVersion each time a program starts to run. When they are no longer equal, I use the Upgrade() method to ensure my settings get brought over from the prior version's last known settings. For example...
if (MyApp.Properties.Settings.Default.ApplicationVersion != Application.ProductVersion)
{
MyApp.Properties.Settings.Default.Upgrade();
MyApp.Properties.Settings.Default.ApplicationVersion = Application.ProductVersion;
MyApp.Properties.Settings.Default.Save();
}
Something like that will hopefully work for you.

Brilliant. Thanks
I'll try it out when I'm back in work tomorrow.
(Although, like I said in my other post, it suddenly seems to be just working now although I'm sure it shouldn't be.)
Cheers

Hello!
I have a datagridview consisting of two columns and many rows. One of the columns consists of texboxes and one of comboboxes.
Sometimes the user wants to select many of the rows and change either the textboxvalue or the combobox value for all the selected rows.
Is it possible to do this in a sample manner?

No, it's a C# windows application.
|
|
|
|
|
it can be done if the user hold the CTRL key while clicking on the rows
or by clicking a row and dragging it...

Yes, I manage to select several rows but I can't change the values for all of the selected rows.
|
|
|
|

youll have to foreach them... somethink like this
foreach(DataRow myRow in DataGridView.SelectedRows)
{
}
changing the data in these rows are not as straight forward as it seems... have you been able to do that with just one row?

We have developed an application and published it. In application we have implimented scanners and camera(Canon Power Shot A640). When we published it was throwing some error as scanner dll is missing. So we pasted all dll's in server where we have published. Scanner Error was solved.
After this app was opening and when we cliked on camera module it is giving error PRSDK.dll is unable to load. after this when we click any button in this screen it is showing unable to load CDSDK.dll.
Please any one help in solving this...

It should work the exact same way. Look-up the protocol windows is using for the communication and then use the associated socket implementation in C#.

dude, you have much to learn about these forums...
if you didnt get an answer then no one here has it... double AND cross posting is concidered rude!
FACT: there arent many people who are experts on crystal reports and the resources on the web are limited.
SOLUTION TO YOUR PROBLEM: - seriously, not trying to be sarcastic i did this a few weeks back
buy a book on crystal reports
im stil waiting for my book so im unable to help with this problem
good luck
