Binding A Textbox's Text Value Setting To A Variable In Configuration File?
Jul 22, 2009
I am binding a textbox's text value setting to my a variable in my configuration file. I only consider the input from this textbox to be valid if it's an integer number bigger than 1. Right now what I was doing is letting the user write whatever he wanted in the box, and I'd only let him save the settings after calling a validation function. The problem seems to be that my binding variable in the Settings class seems to be being updated as soon as the textbox is being edited, and that's a behaviour i'd like to skip. How can I do this?

I have 3 components :
1.Manager : dll containing Iterface definition and other things
2.Implementation: dll containing Implementation of the Interface
3.Executable: (maybe this one could be a external application or another dll using the libraries)
I have particular methods (iside the interface dll file) that extract information of real Implementation from AppSettings keys in order to instance it using reflection. I use the Manager inside the Excecutable, but when I try to retrieve a especific key defined in "Manager.dll.config" (appSettings), the value returned is empty because the configuration file used is "Excecutable.exe.config" I need this configuration information in Manager config file because this Manager will be used from other programs and the configuration must be centralized into that config file to replicate the possible changes to every app calling this dll.How can I to specify that the ConfigurarionManager.AppSettings must extract values from manager.dll.config file?

Can anyone post some example code for an App.config file that uses a binding redirect with the CodeBase tag and an href attribute that points to a file system location? I can't use a standard binding redirect because it is a 3rd party dll that includes the version number in the dll name.

As some of you are aware of, I am fairly new to VB.NET. I am trying to learn as much as I can. I have a textbox which is set to multiline. It's setup to accept a maximum of 500 characters (10 lines of 50). First of all, since it's size is fixed, how can I remove the right bar on the left as im not using it (the scrolling bar).
#2, once a user click on a button, I disable the textbox and display the text. I can set the background color, however it looks like when the textbox is disabled, text is gray and can't be changed. A fix I found is to use a label and hide the textbox, but are there any easier way ?

I have a class from where I need to set objects in another form?
Form1:
vb.net
Function SetMyObject(ByVal frmTarget As Object)
frmTarget.PictureBox1 = Form1.PictureBox1
End Function
(Not tested code, just wrote to show what I mean)So that's the late binding one.I should also say that the frmTarget variable isn't static so thats why I can't make something like Form2.PictureBox1 = Form1.PictureBox1

I am attempting to get 7 NumericUpDowns to display the value of the application setting they are bound to. Each UpDown has its own setting binding. The setting is a decimal datatype with a value of either 4 or 6 as default. I need the UpDowns to display the setting value when the form loads. At the same time, I need any change made to the UpDowns to be saved to the same setting so that the application can both display and use the new value the next time it runs. Unfortunately, the only way I can get them to display anything other than "1" is to hardcode a constant value, and I don't want it to be constant. I think this is the last bug in my application and would love to get it figured out, but I've spent over 8 hours on it with no luck. Here is the applicable code.

1) A string with a value as a date, which would be "10 January, 2011" for example: strDate1 would have the value of "10 January, 2011"
2) A start time, for example: strStartTime1 would have the value of 9:45
3) An end time, for example strEndTime1 would have the value of 18:00

I have a WinForms app with a multi-line textbox. This displays and retains (after loading from the DB) line break characters fine. However if I assign the TextBox.Text value to a string variable and then re-assign the variable back to the TextBox.Text property, the line break characters are lost and replaced with a square character (can't past them here as they just paste as a line break!)

I need to find out how to make the file so the user doesn't have access to it and then how to move it to a more hidden place in the C: drive.

OK So I know WHY I am having the error I am getting. I don't know HOW to fix it. Basically, if the user doesn't have a certain permission, I need to join another table. But .NET is so picky I can't just make two different queries in an IF statement and then use it outside of the if statement. I can think of some ugly work arounds for this, but I would rather not. I am fairly new to .NET I know just enough to be dangerous.
