I am trying to show a message box when an error occurs in a modal dialog window but for some reason the message box is never shown although I know the MessageBox.Show method is being hit. The try catch block is inside of an event handler for a windows form that is being shown as a modal dialog. I know that the event is being fired and that the error is being caught but the message box never opens. I've replaced the MessageBox.Show with another form show and it works fine but I'd rather use MessageBox instead of creating my own error form. I just can't seem to make MessageBox work. Is this a limitation of MessageBox? Here is a simplified version of what I am doing:

From my login form, and when a correct Username and Password has been succesfull and I get a messageBox saying "welcome to your System" (Picture Below) and when I press the OK button in that MessageBox, I want to open Form3.do I add code to the Underlined code (below Picture), or Do I write a completley different code after the messageBox code.

I have a simple desktop application that uses a .NET setup project (.msi file) to perform the installation. On the first installation, everything proceeds in a timely fashion with good feedback for the user.The problem occurs when the user is installing the latest version of the application over an old version on their machine.There is an unacceptably long delay of about 60 to 180 seconds from the time the installer's 'Welcome' dialog [It's not the Welcome dialog, I've removed that from the Start section of the setup project and replaced it with a CheckBox dialog to ask if the user wants a shortcut on the desktop] disappears until the 'Progress' dialog appears. The user sees minute(s) of blank screen and thinks the install has stopped or failed.
In the setup project properties, I've got the 'DetectNewerInstalledVersion' and 'RemovePreviousVersions' properties set to true. So, I believe that while nothing appears to be happening, the installer is actually removing the old version. The 'Progress' dialog does not appear until the new version begins installation.I've been trying to either:
a) Get the 'Progress' dialog to display immediately after the 'Install Icon' dialog disappears
b) Show another dialog while the Uninstall is running to let the user know that the setup is still running and everything is OK.
I have been unsuccessful with both methods. I'm using VS 2008 SP1?
Can I create new dialog results for my dialog forms? And then use them with Form.ShowDialog method?

View 3 RepliesI often use the process of displaying a dialog from a form, with the dialog user input then used to update the main form without any problem. In a new scenerio I launch the main application screen, I then show a login dialog ontop of the main app screen and can launch another dialog from the login if a new user is required. The plan is to update the login dialog (updating a combobox to reflect the addition of a new user) from the new user dialog.
See code below :-
'Update login forms user list as new user added successfully
frmRoomBookingLogin.cboLogin.DataSource = Nothing
frmRoomBookingLogin.txtPassword.Text = "Updating password from dialog"
MessageBox.Show("The password text is " & frmRoomBookingLogin.txtPassword.Text)
[code]....
The messagebox implies the dialog has been updated yet the text does not change. Is it possible to update the dialog when using a setup such as Form -> dialog -> dialog? I'm intrigued as why the dialog does not reflect changes. I have never refreshed/repainted the dialog as never required to in my other examples when updating a form from a dialog and never encountered a problem when using a two tier form setup.
I have an assignment due this week in which I have to make a app that has 5 buttons and a picture box. When each button is clicked it has to show the corresponding picture in the picture box, the fifth button closes the app.
I have the whole form set up the way it should be, but I have no idea how to write the code to make the buttons display the images and close the app.I have the images in a folder within the project folders.
I have yet to be able to find one, the one I found should how to do it using a file opener dialog and a folder browser dialog but that is not what I think my prof wants us to do, as that is more for a picture viewer app that lets the user choose the file of the image they want ot view.
All i want is for the buttons to be linked to specific photos that are part of the application itself and have them open.

View 12 RepliesI have a Dialog that is basically a confirmation dialog on some SQL statements. After the dialog I have an if statement: If frmRelease.ShowDialog() <> Windows.Forms.DialogResult.Cancel then.My buttons are set as DialogResult = OK and DialogResult = Cancel respectively on the dialog form.
For some reason, sometimes my button set to DialogResult = OK is returning me a DialogResult.Cancel, and causing me to skip a block of cleanup code.
I'm using a DLL in vb.net 2005, and this dll show a messagebox with OK option. I would like to close this Messagebox by code.
I was investigating to use SetWindowsHookEx, but I can not detect it. Is it possible to don't show any dialog, or detect the dialog using the dll name?
I have a dialog which opens another dialog. The problem is that the second dialog opens behind the first. Is there a way to stop this from happening? I tried bringtofront with no success.

I am amateur programmer.so far, I can use Visual Basic .Net only. That is all I know!!How can I refer to a MessageBox?or how can I Programatically handle a MessageBox after it is displayed?I need to close a MessageBox after certain time if no response from the user.
View 3 RepliesI'm using MessageBox to give some information to the user, but when such a box pops up, I want it to block access to the main window. So, until the user has clicked "OK", they should not be able to click (or even focus on) the window that's below it.
Does anybody know how to do this? I've noticed that MessageBox has very few functions, so maybe I'll even have to use a different object for this.
I have this
Dim st1 As String = sref.ConfirmLogin() 'A WCF method call.
Windows.Forms.MessageBox.Show(st1 & Environment.NewLine & "blue", "Result")
What is interesting about this is that there is no new line in the messagebox, and "blue" doesn't show up. If I reverse the order, then all is well. If I turn st1 into some other random string, all is well. However, as long as st1 is a string that comes from the WCF call, everything after st1 in the MessageBox is ignored.So what is coming from the WCF call?
The lines are these:
resp.GetResponseStream.Read(buff, 0, 99)
Return Encoding.ASCII.GetString(buff)
resp is a WebResponse object, though that shouldn't matter, as the key is that I take a stream, move it to a buffer, then turn that buffer into a string. What is it about the string that is alterning the way the string is displayed.If I highlight the "st1 & "Blue"" part, and press Shift+F9, it is all there. What I do notice is that there is a significant space beyond the end of st1 and before the Blue. Trim doesn't get rid of this space. My theory is that what is there is a series of Null bytes, and MessageBox is interpreting that as the end of the string and terminating the display at that point, even though it shouldn't really be terminated there. That's especially interesting because I can add in an Environment.NewLine, which would normally add a new line, but even that gets ignored.
I have a Main and a Secondary form. I want that the secondary form appear if the no button in the messagebox is pressed (but the main main don't). Only if I press the yes button or when closing the secondary form the Main must appear. How can I do that?
View 11 RepliesI want to add a yes/no function to a message box (Are you sure you want to exit?) in InfoPath 2007. If the user clicks 'Yes' the InfoPath form closes, if no, then the user is taken back to the form. From what I have read this will not happen in InfoPath. So, I added a new windows form that has the Yes/No buttons.
For the 'No' button, I have (me.close) which closes the windows form and the user is left with the InfoPath form. when the user clicks 'Yes' meaning they want to close the windows form AND the InfoPath form. Below is my code so far.
Imports Microsoft.Office.InfoPath
Imports System
Imports System.Xml
Imports System.Xml.XPath

I have a strange problem here. In my code, variable b string, has the value "Test Test Test". This value we can see while debugging the variable as well as in the text visualizer.Now the problem is, if I show the same string using Messagebox, the value is just "Test". What can I do here to get the complete value.
I am converting from an ebcdic encoded bytes to corresponding utf8 string and doing the above operation. Any thoughts. below is my sample code.

i have vb 2005 and i dont know how to make Ctrl+S work so that it throws a messagebox on the screen.ive tried a couple of different threads, looking for my answer and i cant seem to find it. its just a simple application, but i want to spice it up a bit with a shortcut to save the info on the screen.i dont want to deal with the saving part yet, but just to get vb to recognize that the user pressed the Ctrl key and the s key in combination.
View 5 RepliesI am just doing a bit of error handling. I am just check to make sure that a user has selected an option within a combo box (named cbtitle1) and if option has not been selected throw an error message to tell the user.this if statement is within a save button which once a user click save this error checking runs first then if combo box has an option selected the save goes ahead else it throws an error.I can stop the save function OK but I wanted to put a error icon in with the message box but I get an error when I add it.[code]
View 3 RepliesIm writing a program that is supposed to display a name, which is one array, and then show the phone number to that persons name, which is another array. What happens is when you enter the name, without any capital letters, it will show the number, then show the exception messagebox that says you have no friends with that name. When you enter a capital for the first letter, it will show the number, then it will show the messagebox with the name and phone number. My issue is 2 things,
1.) I need to have the exception messagebox come up only when a name is not entered, and
2.) I need to have a partial code snippet that will display the correct information even when a full name is not entered. [code]
I currently have this which I thought would work fine but doesnt any ideas how to force 2 lines in messagebox?

Dim Result As DialogResult
Result = MessageBox.Show(Message, Caption, Buttons, MessageBoxIcon.Question)
I have an application that has a timer within the main form. Every 5 minutes it checks the database for notifications and if any are due it displays the details in a messagebox. If the main form is the active form, it works fine (message displayed). Even if I create another form and display that modally, the message is still displayed. If I minimize this second form, the message is displayed.
However, if I am writing an email when the timer is called, the message box isn't displayed on top.Is there any way to make sure the MessageBox.ShowDialog method always displays the dialog as topmost?I have tried using a new form instead of MessageBox.Show, setting the TopMost property to true, but that didn't work, either.
