Thanks.

There should be one also here, but AFAIK with VS2005 and FW2.0 this "function" is embedded so you don't need an external tool anymore.

I'd really like to use SYSTEM.CODEDOM.COMPILER or SYSTEM.REFLECTION.EMIT to create assemblies for the compact framework from the regular framework. In other words, dynamically compile code on a PC to send to a handheld and run.
I can't seem to find any info about this. I feel like I could bootstrap into it if I could just get an example or two.
This
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_evtuv/html/etconsimilaritieswithnetframework.asp
seems to suggest I would need to compile specifically for the CF if I want my code to run there, and I confirmed that a simple form compiled in the full framework will choke if I try to run it in the CF.
Does anybody have any pointers or suggestions? Anyplace I could look further?

If I understand your qeustion correctly, you won't find any examples of this. This is because the CF is a subset of the full framework. Form example, compare the Form classes, or pretty much any of them, in the CF and Full Frameworks and you'll notice that the CF classes don't support nearly the number of properties and methods that the full version does. There are also entire classes that are not supported on the CF version.
There is no tool that can take a full version application and "strip it down" to work on the CF version. You have to re-compile the application, and in most cases re-write code, under the CF version in order to get it to work.

Thank you for taking the time to reply.
CODEDOM and EMIT are functionality in the full framework used to compile new assemblies. I would need to write code for the compact framework dynamically and then feed it into one of these classes. The classes would create the new DLL or EXE for the compact framework, and then I could send the new files to a device to be called by the reflection class. I was looking for an example of the compilation part.
I think the trick is selecting the correct libraries to compile with, but I'd really like to see an example instead of wasting a lot of time trying to figure it out from scratch.

Well, you've still got a huge problem. The code that comes out of CODEDOM in the Full Framework is compiled against the FULL FRAMEWORK! This code wont run on the CF. Ever notice that a Form in the CF doesn't support a Window Handle? If you use the Full Framework's CODEDOM, it won't compile against the CF and you can't tell it which libraries to use.

Hi,
I am using DataGrid control to save some records.Is there anymethod by which i can change the RecordCount by which i can read the record of my choice.I tried to assign some value to recordcount but it got runtime error telling that its read-only variable.Somebody please help me with this.

Are you sure your looking at the right property. RecordCount should and is Read-Only for a reason.
What are you attempting to accomplish by changing the RecordCount property?

Hi all,
I'll try to explain what I want to do. I'm starting to learn about arrays and I'm trying (and failing all day) to be able to create a list in a dropdown menu of filmtypes: "Comedy" "Thriller etc.
When I select one of them "Comedy" for example I want that to appear in the list below.
I've attached the code I've written so far:
hope someone can help.
thanks,
Chris
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
With ComboBoxSelectType.Items
.Add("Comedy")
.Add("Thriller")
.Add("Horror")
.Add("Animation")
End With
End Sub
Private Sub ComboBoxSelectType_SelectedValueChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ComboBoxSelectType.SelectedValueChanged
Dim Comedy(5) As String
Comedy(0) = "The Best of Jasper Carrot"
Comedy(1) = "Goldmember"
Comedy(2) = "The Man Who Sued God"
Comedy(3) = "The Life of Brian"
Comedy(4) = "24 Carrot Gold"
Comedy(5) = "Peter Kay"
If ComboBoxSelectType.SelectedItem Is Comedy Then
ListBoxAvailableDVDs. = Comedy
End If
thanks,
Chris

First, the following line does not make sense.
chrischik wrote: If ComboBoxSelectType.SelectedItem Is Comedy Then
Keyword "Is" is used to check if 2 references refer to the same object. In this case, they're 2 completely different classes which will cause the above code to always evaluate False.
You see SelectedItem will return a String reference because that's what you added into the ComboBox in Form_Load. Comedy is an Array reference.
Second, I don't think you need to use an array at all in this case. It looks like you just want to add the selected ComboBox string into your ListBox. So, why not do this?
Private Sub ComboBoxSelectType_SelectedValueChanged(ByVal sender As Object, _
ByVal e As System.EventArgs) Handles ComboBoxSelectType.SelectedValueChanged
If (ComboBoxSelectType.SelectedIndex >= 0) Then
ListBoxAvailableDVDs.Items.Add(ComboBoxSelectType.SelectedItem)
End If
End Sub
|

If you are looking for the "error" then the line:
If ComboBoxSelectType.SelectedItem Is Comedy Then
has to be changed in one of those:
If ComboBoxSelectType.Text = "Comedy" Then
or
If ComboBoxSelectType.SelectedIndex = nn then ' (where nn is the array index)
Also I don't understand this line (and surely doesn't compile):
ListBoxAvailableDVDs. = Comedy
If you want a suggestion you can also go for:
select case ComboBoxSelectType.Text<br />
case "Comedy"<br />
' Code to handle this case<br />
case "Thriller"<br />
' Code for thriller<br />
...<br />
end select

Oops. Good catch Briga. I answered this way to quickly and forgot the DVD titles under Comedy.

Hey everyone
I am new to VB. I need to do a small project where I need to make a real-time graph from the data in a database. What I need to do is to query the database every minute to count the number of records present there and plot the difference of the new count and the previous count on Y axis and the time elapsed on X-axis.
Thanks

I highly recommend the Zed Graph control. It is a free, very nice, professional looking control.
http://www.codeproject.com/csharp/ZedGraph.asp[^]
You'll also need to setup a timer control on your form with a 1 minute interval. Every time it elapses, you should fetch data from your database and then rebuild the graph control with this data.

So does zed control work with VB 6.0 ?
Joshua Quick wrote: You'll also need to setup a timer control on your form ...
The timer and the data fetching from the database is already working. Now what I need is just how to scroll the graph to the left every minute and update the curve.
Thanks

Hello coders,
I am looking for a way to develop a Header Column with a ComboBox Dropdown button.
A sample is shown in here..
http://img510.imageshack.us/my.php?image=headerwithcombo4ge.jpg
Please help me if you know a way to develop that (it could be only a message to be sent to header or another control)
Thanks.
Best Regards
Emre YAZICI

You can create a UserControl to do this, but that is quite a bit of work and advanced.
You can try to find a control with similar functionality, such as this one...
http://www.codeproject.com/cs/miscctrl/listviewfilter.asp[^]
Or an even easier solution would be to break it up into separate controls. You could create several ComboBox controls next to a ListView control. You would then capture the ComboBox's SelectedIndexChanged event to update the ListView.

Thank you for your answer
I have thought that before, but I am not going to use the headers in a listview.
Thanks anyway
Best Regards
