another technique:
Private Sub Txt_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles Txt.KeyPress
If Char.IsLetter(e.KeyChar) OrElse Asc(e.KeyChar) = Keys.Space Then
'allow
Else
e.Handled = True
End If
End Sub

I am using VS 2005 .NET 2.0
I have added a application config file, which contains 2 keys for my application. The config file named appTextSearch.config is created in my application's folder.
Now, the problem is I am not able to read these 2 values from the config file.
serverDetails (see below) returns nothing
ConfigurationManager.AppSettings.HasKeys also returns false
DO I need to specify anywhere in my application to read this application config file ?
</configuration>
<appSettings>
<add key="servername" value="http://a2tmon963:9080/gisgazetteerhttp/addressformatted.do?freeText=" />
<add key="recno" value="30" />
</appSettings>
</configuration>
Dim serverDetails As String = ConfigurationManager.AppSettings("servername")
Dim NoToReturn As String = ConfigurationManager.AppSettings("recno")
|

|
|
There shouldn't be a "/" in the first <configuration>
|
|
|
|
|
Sorry this was a typo. There is no "/" in the first configuration
|
|
|
|
|
It works fine for me then. Do you have a reference to System.Configuration in your Project?
|
|
|
|
|
I do have a reference to System.Configuration
To clarify, I am working with a class library DLL. I realise this is probably why I cannot read the app.config. Does anyone know any way around this problem ??
|
|
|
|
|
Use the following XML:
</configuration>
<appSettings>
<key>"servername"</key>
<value>"http://a2tmon963:9080/gisgazetteerhttp/addressformatted.do?freeText=" </value>
</appSettings>
<appSettings>
<key>"recno"</key>
<value>"30"</value>
</appSettings>
</configuration>

Hello,
I am looking for a solution to use like we had in VB 6 a Command control array.
I need to put +- 20 commandbuttons on a form with the same program code.
The buttons need to have all a different text coming out of a database. The color of every button is can be different to set also out of a data base.
It is for a hotel registration so i need to show the room nrs each on every button , when the room is occupied the button need to be red otherwise green. After clicking on a room nr the bill of that room comes up ,........
I just dont know how i can have a control array like in VB6.
Any suggestions are most welcome.
Thanks
Didier

there are one or two problems:
1.
fritzdjam wrote: compiler.StartInfo.Arguments = " -g -b -z -v ""C:\GDBCreation...
if you need to have a literal double quote, you would need to write \" inside
your literal string
2.
Process.Start() launches a process but does not wait for it to finish (not even to start);
so it tries and reads the results immediately, and finds none. You must wait before calling
ReadToEnd(), using one of WaitForInputIdle, WaitForExit, or HasExited.
Read up on the Process class!

Not true in VB.NET. VB doesn't support the \ character as an escape character. He has to use two double-quotes to get one inside the string.

Sure. I keep forgetting that. Maybe I should actually write some VB lines as a penitence?

Sub pd_Printpage(ByVal sender As Object, ByVal ev As PrintPageEventArgs)
Dim linesPerPage As Single = 0
Dim yPos As Single = 0

' BEGIN READ FILE
Do Until EOF(Numfile)
' Print each line of the file.
If count < linesPerPage Then
FileGet(Numfile, RigoOrdine)
line = Rigo(RigoOrdine)
yPos = topMargin + count * printFont.GetHeight(ev.Graphics)
ev.Graphics.DrawString(line, printFont, Brushes.Black, leftMargin, yPos, New StringFormat)
count += 1
ElseIf Not line Is Nothing Then
ev.HasMorePages = True
'IntestazionediPagina(yPos, leftMargin, topMargin, ev)
Exit Sub
Else
ev.HasMorePages = False
End If
Loop
End Sub
When generates the second page the text is written on the first page

The very same PrintPage event handler gets calle donce for every page printed until the e.hasMorePages is not true.
This means that variables which track the current position of the text and also reading of the text from the file has to happen outside that event handler.
I have some articles on printing that show this being done - suggest you look at the "Printing a datagrid" one as it handles flowing over multiple pages.

I am creating a VB.NET windows application and am unsure at whether i should be publishing the final executeable or creating a install/deployment project.
I have tried the publish route (both to a web url and a directory) and the program installs fine. However i want to control where the exe file is sent and the publish does'nt seem to give me that.
Is this what the install/deployment route will give me?
Or is there a valid reason for using one over the other?
(Yes, i am a .NET newbie)
Regards

I have a simple GUI interface that loads menus dynamically from a range of dll's/plugins.
The problem I face is one of the plugins has a lot of Dependencies and needs to be executed with its own application path to be able to fucntion correctly.
Is there a way I can load it into my GUI but set its base paths for loading assemblies etc to another path.
A brief idea of what i want to achive.
C:\program files\My App\Centralize Gui\Gui.exe
C:\program files\My App\App1\App1Gui.dll
C:\program files\My App\App2\App2Gui.dll
Currently Gui.exe uses Activator.CreateInstance to dynamically load App1Gui.dll which returns a predefined iGUI interface.
Public Interface Gui
Delegate Sub RebuildMenuEventHandler()
Property RebuildMenu() As Boolean
Function GenerateMenu() As System.Windows.Forms.ToolStripMenuItem
Sub AdminLevelChanged(ByVal AdminLevel As RMS.Gui.AdminLevels)
Sub LoadGui()
Sub ExitGui()
End Interface
The Gui.exe then calls LoadGui.
The LoadGui routine does a lot of stuff and has to be able to access and load objects etc from assemblies within its own folder(eg C:\program files\My App\App1).
This is where I hit the issue as it is currently running within "C:\program files\My App\Centralize Gui\" and of course fails to load any of the App1Gui.dll's dependencies.
My gut feeling is I need to do something with Appdomains so that I can get App1Gui.dll to run within its own path but I cant find any good examples on how to achieve this and I haven't managed to get any of my own attempts anywhere near working. The solution works fine if i put my GUI within the App1 folder but this is not the solution as I need to have a single GUI that can control multiple applications.
Thanks in advance for any help/pointers.

I have a VB.NET windows app that i have built an exe file for. I orignally put the .exe file on the c:\ for ease of testing but the app didn't work.
It complained 'PublicKeyToken=null or one of its dependencies. The system cannot find the file specified.'
I have solved this by Publishing and installing the application, instead of just copying the exe file and config file across.
However the publish wizard gives me the option of were to publish the install to but not where the install puts the exe file.
How can i do this?
