As part of a new program, I need 2 forms and an openfiledialog. On Form1, a button event opens Form2. Form2 has an openfiledialog triggered by a button shown below.

View 1 RepliesI am using Process.Start(fileName) to let Windows open certain files outside of my application with their 'default application'.If "fileName" for example is a ".txt" file, it opens the file in Notepad. If it is a folder, it opens windows explorer with that folder selected.This all seems to work well, except when the user enters a file that has no application 'linked' to it.(a file that has no file associations)I have wrapped the Process. Start() in a Try/Catch block so that any errors are caught and displayed.When I now open a file without any file associations (windows does not know with which application to open it) it tells me that it cannot find any application to open it with. (The exact error is in dutch so I don't think that's going to be much help here, but I think it's clear what's happening, no?)What I would like to happen in this case is that the windows "Open With" dialog comes up, asking the user to select an application to open the file with. Now it just displays the error message and continues, making it impossible for the user to open the file unless he browses to the file manually and sets up the file association, something many users probably don't know how to do.
View 8 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 have a form which has a picturebox and after clicking on a button another form will appear with a picture box containing the exact same picture. I use this line of code:Image1.Image = vImage.Image..The thing is after I do this i need to hide the form and show it again to be able to see the changes.[code]
View 1 RepliesI have a Visual Studio, Visual Basic form that includes an OK button and a Cancel button.
What I want to do is have the OK button save the options that the user chooses and of course the Cancel button discarding them and returning them to their previous values.
But what I'm noticing is that as I'm debugging the form, the values are being saved regardless of whichever button I'm choosing. On the form's properties, I have declared that indeed the CancelBtn is the CancelBtn and that the OK button is the OK button, but the values are still being saved regardless.
Is there a better way to do what I would like this form to do?
EDIT:
Here's the code so far for the two buttons, both are being set to close the window. AcceptOption should save the values and CancelOption should just close the form. I'm sorry if this isn't done well but the FAQ's that I found only mention changing the properties of each button and nothing about the code.:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles AcceptOptionBtn.Click
' Save the Options

I'm having an issue with my app where IE will get brought to the front of the screen when I am switching between forms. Basically I have a form with the man menu which consist of a few command buttons that will start up another form once a user clicks on the button. I do not want the users loading up multiple forms in my application, so once they load one form I end up hiding the main form. So my code looks as shown below when a button is clicked.

I have a treeview control which is being used to browse various folder on the users system drive. It can also be set up to connect network folders using UNC paths e.g "serverfiles". At the moment I'm getting a list of Directories by using My.Computer.FileSystem.GetDirectories however this obviously fails when the folder is password protected.
Is there a way that I can get Windows to open the credentials dialog as you would see in Windows Explorer and deal with the credentials side so then the user name & password is cached as well?
I'm sure most people on here have opened an OpenFileDialog or SaveFileDialog and set the SelectedPath property to point to some directory...
Has anyone done this on a Windows 7 machine and been able to point the thing to a Library? If so, what do you set it to?
At one point I have a dialog form open, but in order to process it, the user might want to access information on other (open) forms. This would necessitate the ability to move/resize/scroll the other forms, but obviously everything is frozen during the dialog. I don't suppose it's possible to achieve this "semi-modal" state, where other forms can be browsed, but no other actions taken?
View 5 RepliesHow 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).
How can I have the Main Form of my app mininized while a Dialog is stil open and avalable for resieving text from the user.

I need a code for the open file dialog that if a file is not supported then a message box appears stating the error. This is my open file dialog code. [code] The message box pops up like it is suppose to, when you click ok the open file comes back up like it is suppose to. When you put in the correct file the message box comes back up again. Also the message pops up even if the correct file is put in the open file. but if you close the file dialog the image is where it is suppose to be.I believe the code for the public sub wrongfile is what is the problem. can some one look it over and let me know what changes are needed.

I have a checked list box that is populated with the text from a text file. I started off with this code:
Dim FileToLoad As String
FileToLoad = TextBox3.Text
Dim fs As FileStream = New FileStream(FileToLoad, FileMode.Open)
[code].....
code snippet that would allow a progress bar to track the input of a text file? Normally I would not bother with this, but the text files are > 10,000 lines long, which is noticable even on a fast machine. The number of lines is variable, so I would assume that one would not use a fixed value to calculate when the progress bar goes 100%.

I have completed the vb tutorial on

and have successfully got a file name from the open file dialog when coded as part of the "Public Class Form1" -> Private Function btnOpenXML_Click function that was generated automatically by vb. The openFD was generated by adding the OpenFileDialog to the pane underneath the form.
Private Function btnOpenXML_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOpenXML.Click
Dim strFileName As String

I'd like to move this code to a module so that it does not clutter my main form1 layout.
However when copy the code to a new module, the openFD is not recognised.
how to I re-declare this openFD or pass it into the function so that it can be used?

View 3 RepliesI'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 have created my own version of word pad. When I click save on the file drop down, the save dialog box pops up, but if I click cancel then my program crashes. I am not sure what I need to do so that if I hit cancel, it will just return to my program.[code]
View 2 RepliesThe following code works fine, however if the user wants to cancel out from the openfiledialog they cant they are stuck in a loop. A loop I created in case they selected the wrong type of data file they could choose again. [Code]. I really need some help seeing where and how to let the user cancel out without the program continuing. I tried some dialog.dispose code but everywhere i seem to put it it generates an error somewhere.
View 4 RepliesI have made a little programme where the user can put in a name to search for a contact.The matches then fill a Datagrid and the user can then choose the one they want and the programm then opens the contact form (from outlook client)The Contact form opens ok, and it brings up the correct contact. If the user then selects the option to "Email" from that from I then get the error message"A Dialog is open" etc...
My code is as follows
Sub GetContact()
Dim objOutlook As Outlook.Application
Dim objNS As Outlook.NameSpace

It seems to be due to Outlook being open or opening?
