Now I know in ASP.Net with a DropDownList you can bind to 2 values, one that is displayed and one that is the actual value, is there a way to do this with a ComboBox in a Windows Application in Vb.Net?

Hi all
I am trying to from my laptop run a program that would tell me who is currently logged into a windows 2003 Ts farm
It would be similar to the program Tsadmin.exe
does anyone have any idea if there is a way to do this via an API or in the .net framework?
Thanks

Hi
XML files could be a option to export files to xls format, of course, these files are not excel format, but if you only want export your tables i believe about they are util to you.
Example: you have this columns in excel
Column1 Column2
Data1 Line1
Data2 Line2
Data3 Line3
In xml you can generate file (text plain file) some this and open in excel and work
<?xml version="1.0"?>
<?mso-application progid="Excel.Sheet"?>
<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet" xmlns ="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet" xmlns:html="http://www.w3.org/TR/REC-html40">
<Styles>
<Style ss:ID="Default" ss:Name="Normal">
<Alignment ss:Vertical="Bottom"/>
<Borders/>
<Font/>
<Interior/>
<NumberFormat/>
< Protection/>
</Style>
<Style ss:ID="s21">
<Font x:Family="Swiss" ss:Bold="1"/>
</Style>
</Styles>
<Worksheet ss:Name="Sheet1">

Hello,
I would like to create a patch for my program. I have a simple window app for testing. Using VB 2005. I have created the application and then added the MSI basic project.
I then went to the project assistant and added the default settings. The project built, installed, and ran ok.
Now I have made some changes to my windows application. And I want to create a patch, not sure now to do this.
I have tried using the quick patch project and the design patch configuration. I am able to create the patch and install it, but it doesn't update the windows application to show the new changes.
Once I have my patch working, should I be able to give the patch.exe to the customer, and they should be able to install it without having to uninstall? The patch should be very small as it is just a few simple changes.
Many thanks for any help you can give me,
Steve

I want to be able to click on an item in a ListBox, then using the AfterUpdate() Sub-routine, be able to store that value into a String variable. My loop is as follows:
***START***
Dim iterator As Long
Dim descriptionString As String
For iterator = 0 to Descriptions_lst.ListCount - 1
If Descriptions_lst.Selected(iterator) Then
descriptionName = Descriptions_lst.Column(0, iterator)
End if
Next iterator
***END***
I'm not exactly sure what the 'Column' does, but apparently this is supposed to get the string value from the selected ListBox item. However, it is not working. I just get empty values for my descriptionName variable. Any ideas?

I only find the ListCount and Selected properties in the Office classes. Is this VBA?

Ya, its VBA using Access. I need to somehow verify that 'if' statement properly, then get the selected item into a String variable.

Hi all,
How could i change text on button in MessageBox?
Ex : If i write :
MessageBox.Show("How to change text","Question",MessageBoxButtons.OKCancel)
-> MessageBox will be shown with "OK" and "Cancel" button. But i want to change text "OK" -> "That's right" and "Cancel" -> "That's not right".
How could i do that?
|
|
|
|
|
You can't. The things you see in a MessageBox are not cusomtizable. You'll have to create your own form class that provides this functionality. It's not that hard. It's just a normal form with a couple of buttons and a label. Maybe even a picturebox if you want.
|

|

hellllo ctlqt,
Dave is correct "The things you see in a MessageBox are not cusomtizable"
U can use
form.showDialog() method to show ModelDialog,
just create a form looklike message box and call it as modelDialog box

i have a label and textbox.
right now i have 75 labels and corresponding textboxes.
i have done their connectivities with database.
after deploying it suppose i want 100 textboxes.
or rather i want to leave this on user that how much labels and textboxes he want.
for that a window wil be there and user will enter the name for label and its value..
but how label and textbox will be generated...?
and how will the database connectivity will be established.
i dont know how this can be done.
can anybody give me any idea , hw do i proceed...???
thanks.
|
|
|
|
|
To make the labels and textboxes you can use a for loop that dynamically creates them based on user input. For the db connectivity, what exactly are you looking for?
|
|
|
|
|
okkk, i think it will do.
but wat abt the conectivity with database..??
like how the connectivities with backend will be established automatically with the textboxes created dinamically.
can u tell me any article or any code for such logic...?

Hello CPians,
I am wanting to do a string comparison but the check is against multiple possibilities, eg: The string can be "SPT", "SAP", or "PRF" and I'm hoping to do this without something like
If MyString.Equals("SAP") Or MyString.Equals("SPT") Or MyString.Equals("PRF") Then
'process here
End If
Is this possible? I've tried some Google searches and haven't found anything as of yet (maybe I'm using the wrong keywords). Any ideas?

Select Case MyString
Case "SAP", "SPT", "PRF"
'process here
End Select
|
|
|
|

Well I found my solution
Dim ProgramTypes() As String = {"SAP", "SPT", "PRF"}
Dim ProgramTypeList As New ArrayList(ProgramTypes)
If Not ProgramTypeList.Contains(sProgType) Then
'Do my stuff here
End If
"Well yes, it is an Integer, but it's a metrosexual Integer. For all we know, under all that hair gel it could be a Boolean."

Hi all.
I've been trying in vein for days to figure this out. I use extended desktop to extend my display to the left, not the right, and when I hibernate and come back, the desktop is extended to the right. So I'm writing an app that will retrieve the extended desktop settings on hibernate and set them again on resume.
I've seen a few examples of using EnumDisplaySettingsEx in C and C#, but nothing in vb.net that helps. I just need to figure out how to determine "This monitor is primary, that one is secondary and is positioned on the left." And then "Set this monitor to primary, set that one to be on the left."
I already have the rest of the app written (detecting hibernate, etc.), but I'm super new to the Windows API and all these structs and translations from C to vb.net are way out of my league.
I'm desperate  . Help!

P.S. I've pieced together the following, and it gets devicename and resolution successfully, but I'm still stuck on the aforementioned stuff:

It sounds like you've mistated the problem. From what you've posted, there's no problem at all, so I question why you're even trying to do this.
Really, there shouldn't be a single reason why you're doing this at all if your display drivers are working correctly.
|
|

|

You are correct. I had a typo in the problem statement that I've updated. What happens is:
[2nd Monitor (extended desktop)][Laptop]
...Hibernate...
...Resume...
[Laptop][2nd Monitor(extended desktop)]
And I'm trying to read the fact that the 2nd monitor is on the left, and then set those same settings later.
Can you help??

The problem is that your trying to throw a band-aid over a driver problem. On my laptop, this problem doesn't show up, using a Mobility Radeon 9000. I would recommend that you see if there are updated drivers before going through all this. Both ATI (AMD now) and nVidia drivers both come with desktop manager software now that takes care of this.
