• Newmanb1 Odd ComboBox behaviour

  Hi, I'm getting a strange behaviour with a ComboBox control, I'll try to make the situation clear: I have a DataTable, wich is correctly filled by a SqlDataAdapter, used as DataSource for my ComboBox. I correctly set the DisplayMember and ValueMember properties and the ComboBox displays and it also returns the correct value after the user has clicked on it. The problem lies here: I need to set the SelectedValue property before the user can do any interaction (I have to display a specific name) but before the ComboBox has been clicked, no matter what I do, the SelectedValue has always a null value!!! I even tried something like: comboBox.SelectedValue = new Object(); but it does not work at all. Any clues Thanks ...Show All

• elhussein application manifest errors

  I'm getting the following error message at on one of my customer’s pc when installing an update to a deployment. All of my other customer’s are working fine. Has anyone experienced this issues or has seen this message "Reference in the deployment does not match the identity defined in the application manifest" Here's Microsoft’s explanation. http://msdn2.microsoft.com/en-us/ms229001.aspx I also saw somewhere in the past, that you needed to deleted the local internet cache on the client’s pc which was done. I've also uninstalled the click once app using add/remove programs. So I guess I'm not sure what to do. Here's the actual error: Reference in the deployment does not match the identity defined in the application ...Show All

• mdrelyea how to represent 2 D data in Grid View?

  Hello, Can anyone help me in this.. Is there any way out to display 2D data in a Grid... Means a data which depends on 2 entities... Sort of bar chart data... or let say Matrix form.... You can do some calculation base on your logic and assign value to datagridview cells manually instead of data-bound,you can also set the row header text if you want.

• athnetix Night Vision

  I am working on a military application that needs to support a "night vision" mode - that is, make the application appear in a green scale color pallet to make it easier on the eyes in reduced lighting. Now, I know I can take an approach that will "skin" or "theme" my application to make it appear green (our GUI COTS product Infragistics NetAdvantage makes this possible), but it still isn't a 100% solution because we would need to re-do all of our images/icons that we use in the app to a green scale version, and then code the functionality to change the images at runtime when needed. Further, because we display maps and map information, there isn't an easy way to change all of the maps into a green scale. Havi ...Show All

• RichardCUK Storing custom class in Application Settings

  I would like to store a class defined by me in the "windows from application settings". This is not easy to do, but it seems to work, mostly: 1) Open Settings.settings with the Settings Designer. Because the dropdown list doesn't allow me to chose my own class, I just use a property of type string. Close the Settings Designer and save the changes. 2) Open Settings.settings with a text editor. Change the type to my class. save the change. 3) Open Settings.settings with the Settings Designer. A property wiht my the type of my class is displayed. Nice :-) From my code, I can create a new instance of my class and assign it to the application settings, save them and read them again. This works for all fields in my class wh ...Show All
