I migrated an application from Vb6 to .NET and there are still a few bugs to fix.One of them is when I want to edit a record, the inputs should have been populated with the coresponding data from the database. Instead, only the drop-downs are populated, the text inputs are blank.
View 10 RepliesI just downloaded the latest VB Express. It seems that thought the functions are available, there are many that are not as fully functioning as they should be, like PRINT dialogs and TIME/DATE dialogs, etc. Are some of these functions not fully developed in VB Express because they are only available to the licensed version?

I have an app that opens MS word. I then open Word's File open dialog and have it pointing to a specific directory to find a file for the user to open. What i cannot do is retrieve the file name the user selected to open. In a Window's fileopen dialog i can read the .fileopen property, however there doesn't seem to be a corresponding property to read in Word's dialog. Is this even possible? if so how do i do it?
View 4 RepliesI can currently make a dialog1 pop up, then the user clicks "Yes" for dialog1, then dialog2 pops up, and if the user clicks "no" instead of "yes", dialog2 reappears again. I've got a headache now, but I will re-look over my code to see if there are logic errors.
I originally had dialog2 and form1 (the form1 was acting as dialog1). But The thing was that I do not how to give properties of a dialog to a form (i.e. not make the user be able to click other windows while this form is open) IF I could have code that says Me.bringtofront (which I have tried) didn't work though. If I apply this command to a form I get an error:
code: Form1.showdialog()
error: Please make form1 not visible. something a long those lines. But what I don't understand is form1 was never open.
What do the standard lines of code do?:
Me.DialogResult = System.Windows.Forms.DialogResult.OK
Me.DialogResult = System.Windows.Forms.DialogResult.Cancel
How can my VB.net application interact with windows modal dialog boxes?
For example when you click an HTML <input type=file> the dialog that opens is a windows form that isn't in my application, so how can I manipulate it?
There may be times when it would be useful for your code to be able to find and close modal dialogs displayed by an application. Perhaps you do not want to have to wait indefinitely for your user's input, or are using the COM Web browser control to automatically navigate Web page and would like to interactively close alert messages that pop up.Digging into our Interop toolbox, we find that this is a relatively simple process using a few core Win32API calls. Starting with the handle of the main window associated with the dialog (this is the form from which the messagebox was shown, whether from your code or from a Web page hosted in a Web browser control on the form), the GetWindow function can be used to retrieve a handle to a dialog windows (called a popup by the Windows API) being displayed (if any). The same function can then be used to enumerate the child windows of the dialog to find a button on the dialog to click in order to close it, and the SendMessage API function can be used to simulate that click, effectlvely closing the dialog window.
NOTE: At the top of whatever code file you put this code, be sure to include the following line (thanks poiygon for pointing this out):Code:Imports System.Runtime.InteropServices this allows for the shortcuts to the DllImport attributes.[code]This sample can be easily modified to close a dialog in another application (by using the MainWindowHandle of that application in the LookForAndCloseIEPopup function, instead of "Me.Handle") or to close any other type of modal dialog message being displayed to your user.
What the icon file filter is for load/save file dialogs. (I know the jpeg one is "JPEG Files (*.jpg)|*.jpg|PNG Files (*.png)|*.png|BMP Files (*.bmp)|*.bmp|All files (*.*)|*.*" But as far as I know you can't use these as icons without an icon editor).
View 1 RepliesI am unable to select a .ZIP folder with either the FolderBrowserDialog (FBD) or the OpenFileDialog (OFD). First off the FBD does not show any .ZIP folders when using it and the OFD does show .ZIP folders but I am not sure how to handle it's path. My question would be how can I handle the OFDs ".SelectedPath"??? I could easily obtain that info with the FBD "FolderBrowserDialog1.SelectedPath", but it does not allow the selection of .ZIP folders.. So now I am trying to do the same thing with the OFD but there isn't any code for obtaining the ".SelectedPath". Here's some code that shows what I am trying to do:

View 9 RepliesI am trying to get my project to be able to save the data been input from a user. I have uploaded a screen shot of the dialog I am currently trying to use. You will see that I have got a combobox for member at the top. What I want is when the "new" button gets clicked then I can add the desired information then click "Ok buttton which will then save the information.
I want to be able to select members from the combobox after multiple have been recorded to be able to delete or edit them. I have got as far as "changing" the combobox to a textbox for input purposes. I have tried a few attempts to get it. I am getting "ConfigurationErrorsException was unhandled"
I'm starting on a new project: multiple desktops I want to accomplish this by making a folder browser system like the desktop.I do not want to have all the file transfer actions invisible So: I want to have the normal file transfer dialogs displayed, with the progressbar, file information, just like windows.What code should I use to display windows dialogs?
View 5 RepliesIn my dialog I want to prevent the user to browse freely in certain places (this is due to the fact that my application will be running in a terminal server environment). So I want to to limit the items that will be visible in the top combobox of the server. I want it to start with "My Computer" instead of the usual "Desktop". Furthermore I only want to add mapped network drives under "My Computer" so that the user won't be able to see any local resources.With Spy++ I have been looking around at what happens when a FileDialog starts.
So far I have found that for each item in the combobox CB_SETITEMDATA and CB_INSERTSTRING methods are executed. By using a hook to the combobox I am able to intercept these messages, but sofar I am unable to determine the exact contents of what is inserted, so I am unable to determine wether it is the "Desktop" item or not.I have also discovered that the "My Computer" node is only added at the moment that the combobox is expanded. So I would need a way to get a handle to "My Computer" and insert an item for it manually
This is what I have got so far:

I have a form that adds new contacts. New contacts are added by pressing an appropriate button and they appear as an entry in the list on the form. I try now to add an edit button that will edit existing entries.User will select a given entry on the list and press edit button and will be presented with an appropriate form (AddContFrm).Right now it simply adds another entry with the same title.

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.
Once a user has selected a file with the open file dialog, how can I handle this action? For example, if the user has selected a .txt file and has opened it, how can it get the data from the file? How can it return the path that the user found the file in? Then, how can it save the file?I know that there is a OpenFileDialog.OpenFile() method, but I am also pretty sure this is not what I am looking for. I have also tried the ToObject method, but I probably messed up somehow.

View 24 RepliesI am developing an FTP program which: Watches a folder. If a new file is dropped there then upload it. Tells user if uploading and when complete. All the above works, however I wan to add the items to a listbox that are being uploaded. So if I dropped 3 items there it would look like :
Upload Listbox:

I tried using que, but with no luck as the program just hangs whilst it uploads. So I had a search and looked into multithreading and I tried to implement it, but I can't get it to work as it gives me some 'delegate signature' related error message as you can't pass in values when trying to use 'AddressOf'.
