  Hi All, I have a problem while trying to set "NULL" value to my datetime parameters. I have two datetime parameters (AllowNull=True) on my report.

If user set any datetime value, I am sending "String.Empty" value to my paramaters in order to set them as NUL ...Show All

• Visual Studio Express Editions Newbe How to questions(loops)

  How do you place five choices from a combo box into a loop. In other words I have five items in a combo box that I want to place in a "for loop". For example, I have items such as choice1, choice2, choice3, choice4 and choice5 inserted into a combo box. Also I would like to know if it is possible to place these choices into a "do while loop". Any help welcome The controls has an items property which is simply a collection.   You can iterate around it using for each construct or determine how many items there are and then use any of the looping constructs. There is nothing special about the items collection in a combobox as against any other collection and iterating through the items. Is there an ...Show All

• Visual Studio 2008 (Pre-release) DLINQ question

  I just finished watching the "The LINQ Framework What's New in the May CTP" presented by Luca Bolognese. The video discusses DLINQ. question #1 I am a student and just starting to learn stored procedure of SQL. Correct me if i am wrong but my interpratation to the demo is that this DLINQ prevents you from creating sql stored procedure and your database query will mix up on your c# code or the business logic of the program. is that manner ideal would it be better if the sql code or the dlinq code is in a separated file and not mixed up with the business logic code quetion #2 would this DLINQ work with other database like MySQL, Oracle, etc this is my first time i have seen a video of LINQ. please correct me if i am wrong with my interpre ...Show All

• Smart Device Development Convert a bitmap to an icon in compact framework for ppc2003

  Hi Everyone, I am trying to convert a imagelist image (a bitmap) to an icon so that I can use the graphics class to draw it with transparency. However I cannot work out how to convert a bitmap into an icon - I've found samples like this: Bitmap bitmap = new Bitmap(16, 16); [..] Icon icon = Icon.FromHandle(bitmap.GetHicon()); But this doesn't work as GetHicon is not supported in the CF. Any suggestions Regards Mike Oleary With a bitmap you need to specify what the transparency color is - and in our application this could be different accross each picture....so too hard. With an icon it knows the transparency automatically - so removes this issue. ...Show All

• Visual Basic How to automate application procedures unattended?

  Hi, I have an Access 2003 VBA application that basically does the following: The end user opens the app, clicks on the browse button to import a text file from a folder. Then in the app, when the user selects the order number that was imported, they can then click a print button to create a report to print to an adobe pdf print driver. It then creates a pdf to a location where ever I specify. Is there any code in vb.net, or a process that I can automate the above actions unattended Thanks in advance. You could use a filesystem watcher to monitor the directory where the text files live and use its created event or changed ev ent to fire an ADO routine that would open the text file and then import ...Show All
