Create A Form With Translucent ClientWindow - Looking For A Cleaner Method
Mar 5, 2011
I wish to create a form with a translucent clientwindow but want to have all contained controls and the form border display as normal. Setting the form's Opacity level dims the entire form including its controls and this is not the effect I'm trying to achieve. I have achieved the desired effect by placing a second form behind the main form (with the main form's "TransparencyKey" property set) and adjust the background form's opacity level. This added a few issues to overcome in terms handling the z-order, handling click-through through the main form, and an additional form in the Alt-Tab sequence that I did not want.

I am using normal windows form application. I wanted a way whereby I could create a layer over my form which would be semi transparent and nothing would be accessible until I click a button or do something like that. What I want is similar to a grey sheet that covers your screen in vista or 7 when user admin Yes/No box is displayed. Nothing is accessible behind. Or as you might see in some webpages where till we dont click a button or so the content behind is inaccessible.
Actually I want this to apply only on my mdi child form (a particular one) and it should enable me to see whats in the form but semi transparent and till i dont click a button on it, the content behind should'nt be accessible. Kinda like what you see in webpages whereby there is a button in the center and till you dont click it you can't select or click on content behind it.

sometimes, when I use Form.close() when debugging my program, although the form is closed, the application is still running. I noticed this behaviour when using the msgbox function.

I wrote an application which parses a website and downloads an mp4 file from website. User can select the path where he wants to download the video. When I try to download I get an exception for the file, Access Denied to Path. When I gave the permissions to folder that I chose, then works fine. How can I resolve that problem? End-User will select the folder. How do I change the permissions?

I have a large problem with inheritance in vb.net. The problem is the following:
I have 2 forms => frmBase and frmChild
In frmBase i want to create a method Called StartWorking() and i want frmChild to inherit this method.
But here is the tricky thing: when frmChild.StartWorking is called i would like the following => without calling MyBase.StartWorking()
I want frmBase.StartWorking() to be executed first and after a test in frmBase.StartWorking if blnValue is true then frmChild.StartWorking has to be activated. if blnValue is false that frmChild.StartWorking cannot be activated.

I have some HUGE text files (easily around 2000+ lines) I need to clean where some of the formatting is like this:
CODE:
Of course there are more than 2 words in the lines, but what I said was just an example. I have to clean these files and I just want to know how to delete the whole line after the spaces (including the gibberish), but I don't want to delete the spaces in between the words that need to stay.
I was thinking I could test for 2 or more spaces and if that's true then delete the rest of the line beginning at the first space. The only issue is there are tabs sometimes between the words and I don't want to mess with those right now. (I have no clue how to make source that deletes spaces but not tabs... Perhaps you can single out tabs?)
Because of the formatting to make the text files look "cleaner" there are sometimes 5 (least) - 8 spaces (max) between each some words. So should I check for 9 spaces? (1 more than 8). There seriously are huge amounts of spaces between the words and the gibberish.
I'll worry about formatting the text and what not later, right now I'm only asking for help with the spaces and gibberish issue .
I'm usually a C++ man, not used to VB.NET (2005) but I will only be using this project for cleaning these files and the dialogs are much easier to make than MFC for C++. So I figured this would be much faster and easier (except I have very little experience with VB.NET)

I've been creating short test apps repeatedly to try to understand some of the concepts in VB.NET.For the most part it has been illuminating.I read Bucky's .NET knowlegebase tutorial on passing objects as parameters to newly created forms. He shows how to create a new class that inherits from the base form class and define a New() method with parameters Extending the concept I thought about doing the same thing with a form that was created at design-time (In this case Form2).

I've got this code here, hard coded into a button. What I want to do is create a module with a method, let's call it "openFile."
That way, in the future, I can just call openFile("default directory",file type, etc etc) and also being able to set the input from the reader as the text in a text box or something all in one line of code. Is this possible? I don't know anything about writing modules or my own methods/API or anything like that...Can someone point me to a tutorial about this?
Here's the
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim filesOpen As New OpenFileDialog()
filesOpen.InitialDirectory = ("C:") 'set the default directory

I have a small program which draws some lines with a method called: Drawlines But Now I want to call this method in the load form routine. So if the form is loaded the lines should be drawn in the picturebox. But is this possible or should the form first be loaded completely before you can call methods in that same form?

I'm working through a book that does not provide a lot of example code and what it does provide is in C#. The book refs vs 2005 but I'm using vs2008. The author asks for the user to create a solution with two projects, one winforms and the other a class library (called DependentAssm). The class library is added as a reference to the winforms project In the class library, he asks one to create a new class called SayHelloComp. The project created a file called class1.vb, and a class called class1 which I renamed to SayHelloComp. I left the file name alone, that's ok right?

For the last week I've been trying to create an async method. I tried the MSDN article How to: Implement a Component That Supports the Event-based Asynchronous Pattern but it does the work in a method in the same class. The work I'm doing is a lot more complicated and is its own class. The problem I'm having is the class doing the work cannot post the progress or completion as the methods that handle this stuff is in the parent class.
