Get Return For Dialog OK Or Cancel?

Jun 11, 2011

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).

Dialog OK Button Sometimes Returns Dialog Cancel?

Jun 30, 2009

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.

Cancel Dialog - Handling Enter Keypress

Apr 4, 2011

I'm building a Dialog in Winforms. It's got the two OK and Cancel buttons that are there when you create it, which is what I want. In this dialog I also have a TextBox and a Sub (coding in VB.NET) that handles its KeyPress event. I need stuff to happen when the 'Enter' key is pressed. Now, I've done such KeyPress handling times and times again. This situation, however, is different, because as soon as 'Enter' key is pressed, the dialog automatically assumes you're pressing the 'OK' button, returns a result and closes.

In both the Designer and the actual form when running the application, the OK button is highlight, which means is has some kind of a focus (for the lack of a better term) at all times. How can I disable this feature of a dialog? When I debug my code, pressing enter does not even get to the sub handling the KeyPress event. It simply closes the dialog and returns the result, therefore I can't really step through the code and see what happens behind the scenes. To restate the question, how can I disable this functionality?

I tried some dialog.dispose code but everywhere i seem to put it it generates an error somewhere.

Return To First Dialog

Nov 9, 2010

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).

Use Color Dialog To Return Color As String?

Jun 11, 2011

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?

Get The 'Progress' Dialog To Display Immediately After The 'Install Icon' Dialog Disappears?

Jun 4, 2009

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?

Passing Information Between Forms/dialogs (Form -> Dialog -> Dialog)?

Dec 22, 2009

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.

How To Use A File Opener Dialog And A Folder Browser Dialog

Jan 27, 2010

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.

Return An Object As The Return Value Through A RealProxy Transparent Proxy?

Oct 7, 2010

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

Cancel An ASP.NET MVC Action?

May 12, 2009

This should be simple, but the answer is eluding me. If I've got a Save action in my controller, and the save fails, how do I cancel the action without disturbing what the user entered? For example, Index is strongly-typed of "MyTable":

Function Index() As ActionResult
ViewData("message") = "Hello"
Return View(New MyTable)

[Code]....

In the Catch, if I put Return View(form), I lose the message passed via ViewData. If I redirect to Index, I'll lose what the user entered. I think I've seen the simple (correct) way to handle this before, but if you don't know what to search for, it's hard to find.

How To Cancel Thread

Jun 12, 2009

I am not familiar with threads, but the project I am working on has a bunch of them. There's a thread for the main form, then threads for activities like a calculation, converting files, etc, so that the user can kick off a calculation job and then kick of a conversion job that will run at the same time. Typically, calculations can run for hours and hours; conversions and other threads may only run a few minutes.If the calculation runs into a problem, how do I cancel that thread? It looks like the threads are controlled (driven?) by the main form, but I'm at a bit of a loss.....
