Here is my main problem. am succesfully display the form but the gif animator is not spining ,and the text in the form and the gif animator is like a white box and no visualy displayed.I got some time on the internet to research it and most propably the problem is mostly seems to be the threads ,but i dont know how to correctly configure it,
PS . i dont want to use the data excecution in the form2 ,becuase if i doit like this ,then when ever i want to display a waiting msg for any other process i will need to implement onother form.i would like to keep it universal and calling it when ever i want and close it as my data excecutes.form1 has some proceess to do. e.g
private sub DoMyJob
WaitingMessage.show

I am using Visual Studio 2005 for coding. I am doing an exercise where I have to create a data lookup program. The program is to illustrate the concepts of using a database to look up information based on user input. The program allows a user to input two search criteria for a product search. The program then displays each individual search result, or record that meets the search criteria in a message box. I am not getting the message box and I don't know why. No errors are present during compiling so I have no indication as to where the problem is.

How can I assign a value to a message box for when the default value displayed in the text box is unchanged. ie. If my default value is 17 and the user clicks ok without retyping a number, the Input value displayed in a textbox will be 0.
Currently I have:
Public Class Form1
Dim MyValue As Double
Private Sub But_EnterInput_Click(sender As System.Object, e As System.EventArgs) Handles But_EnterInput.Click
MyValue = CDbl(InputBox("Input a value", "Data Input", "17", 200, 400))
[code]....
This works however if the user types 17, the textbox will read 0. not what i want.

I have written a very simple Windows Forms App. which copies files from my hard drive to my USB flash drive.The app. works ok, but while it is running (copying files) the title bar displays (not responding).I have an idea this is due to the time it takes to do a large copy.
I have two questions:First, I want to add a progress bar, as a visual indication as to how much is left to copy, but I don't know how write the code required for the progress bar when copying say: C:*.* (including all sub-directories)
Second, to stop the (not responding) message being displayed in the title bar. Would I need to run the copy as a background process? If so, how?

What is the proper way to call up a form and wait until it receives a replay before moving onto the next code step? [Code] Now lf is the login form that waits for the users password and then, depending on if its correct or not when they hit OK it should send back a true or false (isLogedIn). Currently i do not know how to have the code wait until it receives something from the login form before moving onto the next code.
If i use my old code here:
Do Until isLogedIn = True
isLogedIn = isLogedIn
intX = intX + 1
Loop
It never ends if the user puts in a false login password so it just keeps waiting.

I'm trying to make an autoupdater, so I've made it search for updates in the beginning and that works fine. But now when the update form is supposed to open, it goes a while and then it says "File Download Complete". So that means the form must have been executed, but it does just not appear. But when I click ok on the dialog, the updater form appears, but with all controls white. Here's my updater.vb: [URL]
I'm using Kleinma's WebFileDownloader class.
I suspect that the problem might be that the updater's form doesn't get it's events handled or doesn't get redrawn.

I been playing around with some code I found on internet and I am probably almost where I need to be. Using the printdocument I am able to get the active form in my project to print. That works fine. MY nextr issue was to get the form to print so that it is Black & white. No shading etc.. So I found a routine on internet that will take image and turn to B&W. Problem: IF a text box fields background color is too dark then the entire box shows up in black. If a text box field data is Selected it also is too dark and comes out white.her is code I found for turnign to B&W
Public Function PureBW(ByVal image As System.Drawing.Bitmap, Optional ByVal Mode As BWMode = BWMode.By_Lightness, Optional ByVal tolerance As Single = 0) As System.Drawing.Bitmap
Dim x As Integer

I've wanted to know the answer to this question for a long time but I never really took the time to ask anyone. My question is, why do rounded edges or drop shadows of transparent form layouts turn white. Take a look at the following image to know what I'm talking about.

I have a VB. Net App where I want the user to open a modeless form which contains reference information about items in a select box. If the user double clicks the item selected in the list box a modal form is opened to edit the item.I want the previously opened reference form to remain active/enabled, that is, I want the user to be able to click on it, move it, etc.I was able to get the form to at least show up on the task bar by setting it's "ShowInTaskBar" property to true, however, when it comes to the front the user can still not move it to the side to view all of the Edit Forms information.

On each of my form I have put an 'Exit' button. When user clicks it, another form is displayed (I don't want to use 'MessageBox') asking user whether he really wants to quit. If user clicks yes the form closes. If user clicks no, form is redisplayed.
However, out of 4 forms only one form refuses to redisplay. The code is exactly same on all forms. I have included 2 Express 2008 projects showing one form each in the zip file apps-ssk.zip

I have a section of code in which I want to display a messagebox after a form is displayed... as the form loads. me.show messagebox.show If I don't use me.show first, the messagebox appears before the form is displayed. If I do use me.show first, the form appears, but is not always complete before the messagebox appears. Is there an easy way to poll the form to see if it is done displaying without using a timer?

I have a parent form, which can lanch a dialog box. A wrong selection in the box launches a message box with an error message. When the message box pops up, the dialog box disappears, so the messagebox is sitting on top of the parent form.Once the user clicks "OK" in the messagebox, the box disappears, and only the parent form remains.How do I make it so that the dialog box remains when the messagebox is displayed? And also, I want the dialog box to remain when the user closes the message box. The user should have the option to make the right selection in the dialogbox once the messagebox disappears.I tried to hunt for a property for the dialog box to achieve this, but couldn't find any.
Here is the code in the parent form to lauch the dialog box, and to also launch the messagebox, when the user has made a selection in the dialogbox:[code]Am I having this problem because all the code to launch the dialog and message boxes reside in the parent form? If I put the code to launch the messagebox in the dialog box, would that make the dialog box persistent when the messagebox is launched? I am putting all the code in the parent form because it can process the DialogResult.

I have a help file which is in html format and is displayed in a form containing a web browser. I initially want this to be copied to the output directory so that it will be there when the programme is installed and i can then use the file path of the output directory to display the help file.
Can anyone advise how i would do this, and also if when the user installs the program, they decide to change the default output directory how i would i get my application to know where the helpfile will be?
