• Suman Ghosh Dynamically choosing a UI library

  Hello All. I'm working on an educational app that is targeted for ages 6 and up. I've got two versions of the UI library, simple (for the youngsters) and normal (for the not-so-youngsters). Both libraries are self-contained and localized, so UI upgrade is simply a matter of file replacement. The user can switch between normal and simple at runtime simply by selecting a menu command. The way that I'm doing it now is by maintaining a persistent UIState variable and checking it each time I need to open a form. That's the problem. I'm wondering (can't find anything on the forums or in MSDN) if there isn't a way to make the check once, initially, and responding to the user changing the option, and not having to check again. Basically, ...Show All

• xdzgor How to pass the combobox value as a parameter to a database?

  I have 3 comboboxes and one textbox. How do I pass the chosen values from the three comboboxes and the information on the textbox as parameters to a stored procedure Thanks for the help. Where does the term "SelectedValue" come from I know it must have to do with the combobox, but its just a string object. That made sense..Thanks. If you look at what Intellisense shows when you type "MyCombo.DataBindings.Add(", the second overload shows three parameters, the first being "string PropertyName" ... IOW, what property of the ComboBox you're binding to. And that would be "SelectedValue" ... when the u ...Show All

• PCSQL66 include vfpoledb.dll into .net build (VB.NET 2005 windows forms)

  Hi, I need to distribute vfpoledb.dll along with my application, the dll needs to be placed into C:\Program Files\Common Files\System\Ole DB (create if doesn't exists) and register it using regsvr32 How can I do that Thanks, Igor Or, better yet, use Bootstrapper Manifest Generator to create a bootstrapper package for this .exe and use the bootstrapper (setup.exe) to run this install before you install your application. Works with either ClickOnce or Windows Installer. If you do this, you can post your FoxPro OLE provider bootstrapper package on GotDotNet for others! :-) I made my own bootstrapper for this: here is the package.xml within the 'en' directory for my bootstrapper (vfpoledb.e ...Show All

  Hi I had a working vs 2003 application with access backend. I added a couple fields in a table in access db and then to allow user to have access to these fields via app I did the following; 1.

• R Raghu Merging arrays

  Hi All, I am trying to find answer for this for the past 5 days and I didn't come across a reasonable solution. What I am looking for is ... I am getting no.of two dimentional arrays from one part of the program. And I need to write these array data to Excel. If I get say 50 arrays, then I need to call the Excel writing function 50 times, which opens, writes and closes excel object each time when it get called. This results poor performance. So I am looking for better alternative. I came across with two solutions a) Keep the target excel open and close only at lost b) Merge all the arrays into a single array and call excel only once. I feel option b) is more suitable for me as in case of a) I need to open multiple exce ...Show All
