A table in a database ? You need the unique Id and then just write SQL that will update the record in question, and call it using ADO.NET.

Hi all,
I would like to create a list of cities that are associated with the country flag that I would use in a combo box or list view. I have tried with the Imagelist but you cannot associate it with a word ?
Thanks,

You'd use a dictionary to associate two groups of objects, probably storing the city name as the key and the index into your image list as the value.

Hi all,
I am a beginner in VB 2005  and I am looking for some help.
I am creating a application that will use a small database under the form of a txt file (called *.dat). Here is an example :
ServerName;IP Adress; port_number; etc....
1) How can I update automatically my listview or checkbox with this information as I do not want it to be hard coded?
2) Also I would like to store the parameters (or Options that the user as entered via the application) in an *.INI file and be able to read them at the launch of the application so that I can populate the options fields?
I know that it is an old way of proceeding but easier for me to maintain.
Thanks,

1 - you'd do better to store your data as XML, or, at least, create a struct that represents one data item, and write code to build a list of items from your data file. Then make that the data source of your control.
2 - Sounds good. Again, XML is probably easier to work with. Then all you need to do, is read the file and set your state from it on startup, and store your state to XML on close.

Does anyone have experience calling a Cobol/DB2 stored procedure from .NET? It is not an easy thing to find on the web as I'm sure most companies have tried to get away from this. We still have them because they must serve as the link between our distributed apps and an IMS Database

How do you write a stored proc in Cobol ? If you have a database, then it needs to support ODBC in order to create a link to ADO.NET. Otherwise, it's going to be tough going, I reckon.

It's pretty stupid. Basically, we have DB2 installed underneath IMS. Programs have to be written in either COBOL or Java and called in order to get to the IMS data from a distributed app written in either .NET or Java. It's certainly not an ideal situation.

Hi
Please help me out in Progress Bar Control in VB6.0
Progress to show until my 6 functions is completed

Have you tried google ? Progress bars are kind of trivial, you just set the maximum value, and keep incrementing it until the tasks are done.
Also, why are you using VB6, which has been a dead language for some time now ? You plainly are very much a beginner, why start on a language that no-one uses ( and that sucks ) ? VB.NET express edition is free.

Dear All,
please help me how to
Convert Format24bppRgb to Format8bppIndexed in c#
I would really appreciate your help.

Hello,
Look up the contents of the System.Windows.Media.Imaging namespace, namely PixelFormat and FormatConvertedBitmap. That should get you started. You'll need references to System.Windows.Media.Imaging and WindowsBase.

The easiest way is to create a new 8 bit bitmap, and draw your 24 bit image onto it.

Hello every one
I am using DataGridView in my VB2005 Express application, I have following issues
- How can I restrict the maximum size of text entered by the user in a particular cell
- The second (requires a bit lengthy description sorry for that)
o After the grid is created the user can click on the cell header to align the rows in ascending or descending order.
o Now if I have a grid with 10 rows(say) and have data only in 2 and the user clicks the cell header then the blank rows come at the top of the grid
o How can I make it sure that when the column header is clicked the blank rows stay at the bottom only i.e. only the rows with data are sorted
- This one is related with previous issue : Can I some how make it sure that one row with data can also be not included in the sorted alignment, i.e. the row acts like a non moving row at that place only
- Is there any property by which I can even disable that sorting feature??
Regards
Nishkarsh

1 - if you're creating a textbox, you can specify in it's properties the maximum length
2 - You should not have 'blank rows' at all, this is a problem with your overall design. You should have an option to create a new row if a user is entering a new row, not have 8 empty rows there
3 - you have to write your own sorting algorithm and make it work in the manner you're describing.
4 - yes, you can turn off sorting
