I have a WinForm that is used as a Dialog with just OK and Cancel buttons. So:[code]I have an If/Then to see if the user pressed OK. If they pressed OK and there is a validation error, I need them to go back to the dialog and fix it.[code]What would I put in Case Windows.Forms.DialogResult.Cancel to take me right back to the first dialog as sr.DialogResult = Windows.Forms.DialogResult.None doesn't seem to be working?I've tried raising the event sub again (it's a click from a menu item), but this doesn't work with the technology I'm using (VSTO Ribbon).
How can i catch the return of say an OpenDialog/Save Dialog/Color dialog?
For example i want to know if the OK or Cancel button was pressed and use a goto statement that jumps to a section of code that exits the sub to avoid an error (especially in the case of pressing cancel when using an open dialog).
i am creating my own message box. My msgbox contains 4 button , so i want to return an integer value as the button no. that was selected (i.e return 1 for button 1, 2 for btn 2...)i tried me.dialogresult=1 , but its not working
How can i use the color dialogue to return the color selected as a string? So if i was to select red i would like the return to be "Red" and so on so fourth.Another thing i would like to ask is if it is possible to return the color selected as a string in hex color code form (like what is used in HTML for example #FFFFFF, #000000 and so on so fourth).I have a feeling though that it can only be returned as R G B integers but maybe there is a way of converting these to hex color codes?
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?
Is there a way to launch a Modeless Dialog that stays active even when a Modal Dialog is launched? Can I put the Modeless Dialog in a seperate Thread or something like that?
I 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.
Is there a way to launch a Modeless Dialog that stays active even when a Modal Dialog is launched? Can I put the Modeless Dialog in a seperate Thread or something like that?
I 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'm working up a system where I plan on using RealProxy objects to enable intercepting method calls against a set of objects, handling the call, and then returning appropriate results. This works just find for simple return types like strings or ints, but I can't seem to return objects from the RealProxy.Invoke method. Everything works. I get no errors, but the returned value is always NOTHING, instead of an object.
I've worked up the smallest sample code I could, and have included it below. Essentially, just call RPtest and single step through. The code creates a simple object, RPTestA, with a string field and an object valued field It then retrieves the string
I'm making a Visual Basic GUI application to display whether a number of my ports are open for people to know whether things like my website and my Minecraft server are open.My problem is I have absolutely no idea how to do this in Visual Basic.Basically, I'm asking for something which sends a signal to an IP with a specific port, if it is open then return true, if it's closed, return false. Similar to: http:[url]....
I would like the following function to return Nothing if the element with the specified key is not in the collection. Instead, it returns an error - something to the effect of "no element found"

In order to return a value from a VB.NET function one can assign a value to the "Functions Name" or use "return value." I sometimes see these inter-mixed in the same function. Personally, I prefer the return. My question is, what is the internal difference, if any, between the two?
I've been tryiing to use the Print Dialog control in Visual Basic. Can someone provide me with an example on how to do this and walk me through it step by step?
In printing, I want to draw a square around the text that I am printing. I am trying to make notecards and would like to have text on one side and a word on the opposite side. I would like to put a square border around this. I have not advance to the graphics stages yet. I have in my toolbox--a control that says rectangle and circle. Can I use any of these controls to draw the box. What type of file(ex. doc or .pdf) do I store the file as if it has a graphic like this in it?

See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

For my program I've developed the code so that when I click a button a textfile automatically opens without the dialog and shows in the textbox;
Dim FILE_NAME As String = "C:ContactsCornwall.DOOS" If System.IO.File.Exists(FILE_NAME) = True Then Dim objReader As New System.IO.StreamReader(FILE_NAME) TextBox1.Text = objReader.ReadToEnd objReader.Close()
However, can this be done for the Save function aswell, so that when I click Button 1, the file automatically saves to C:Cornwall.DOOS instead of having to use the Save File Dialog
I am currently working on a custom control which - unforunately - also includes a Dialog. My problem: I can't find a way to set the Dialog's location! I want the Dialog to be exactly the same size and Location as the ParentForm. The size worked fine with
Me.Size = MyBase.ParentForm.Size
However, the same trick does not work with
Me.Location = MyBase.ParentForm.LocationListing SPEC's is not a review !!! :-)

I have a class where I would like to call a print dialog sub within the class itself.In my class I have the
'TODO Private Sub pdPrintTag_PrintPage(ByVal sender As System.Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles pdPrintTag.PrintPage
[code]....
I copied the sub from a form class....which I believe removes the handler, so this does not work for me. How could I get this done?
I found some code posted on here by .Paul to print the contents of a Richtextbox control with the colors, etc. Does anyone know how to add the print dialog so the user can change printers if needed? I could even pull up a list of available printers -[url]...
