View 3 RepliesI have some VB code which makes use of a COM api and results in a certain dialog box popping up on the screen. My program is a console application, that needs to run in a batch file, but I haven't found any other way to do things other than finding a way to automatically manipulate the dialog box. Here is the api call (omitting setup code) that results in the dialog popping up:

I made a program that is started and running in memory and minimized to the system tray.
When it is first launched it registers global hot keys in windows.These hot keys are used for resizing the current focused window. I'm trying to use it so you can hotkey windows to resize to half the screen, a third of the screen, etc... For instance, if I have two notepads open and notepad 1 is focused and I hit Ctrl+Shift+LeftArrow it will resize notepad1 to the left and half the size of the screen. I have notepad 2 focused and Hit Ctrl+Shift+RightArrow and resize notepad2 to the right side of the screen. So, I can easily see both windows at once.Now, I can successfully get the focused window handle when the hot key is pressed. I'm stuck at this point.
I can use the Windows API call:

I am trying to get a list of files using this line of Dim files() As String = IO.Directory.GetFiles("D:", "*.*", SearchOption.AllDirectories)But it errors out on folders that are inaccessible, like the RecycleBin folder & the program stops. So how do I get a list of files in all folders, while skipping the inaccessible one
View 1 RepliesWhats the best way to handle the connection to a db when it's accessed often? I have an app where the user selects an item from a drop down list(call to the db) and then a picture of the item is returned along with it's relevant information(another call to the db). Small application but basically every action results in a call to the database. Should i just be filling like a global dataset and then accessing the information from there(if thats possible)? The database is stored locally(currently an Access Db but will be SQL in the future)

View 11 RepliesI am writing an audit file that is writing the username, time, and the old/changed values of several variables in the application for each user when they use my application. It is using a FileStream and StreamWriter to access the audit file. All audits for each user will be written to the same file. The issue is that when two users are updating this audit file at the same time, the "old value" of each of the variable is mixing up between the users.
Dim fs As FileStream
Dim w As StreamWriter
Public Sub WriteAudit(ByVal filename As String, ByVal username As String, ByVal oldAddress As String, ByVal newAddress As String, ByVal oldCity As String, ByVal newCity As String)
[code]....
This lives in an AuditLogger class, which is referenced via an instance variable (re-allocated each time the function is accessed).
I have the membership provider setup and its currently pointing to a SQL database on my machine. The role based access works and I have a menu that is security trimmed. The user can only get to pages that they have access to.When an anonymous user tries to get to a page that they dont have access to it brings them to a login page so that they can login. That is fine. But when a logged in user tries to get to a page they dont have access to(Usually by typing in a URL) it brings them to the login page again asking them to login(except there already logged in. I'd like to either take them to a different page or somehow tell them they don't have access.

I am developing a Open/Save dialog that has reduced access to the system (no editting, moving or deleting existing files and folders). I have been succesful at achieving these goals now and I only have one thing left to tackle, but I can't figure it out yet.I want to change the things that are displayed in the top combobox. I want "My Computer" to be the top element and then show specified hard drives beneath it.
I have achieved all my previous goals by using hooks into the default dialogs and I wonder if my last problem could be solved in the same way.
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?

View 13 RepliesIs 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?
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'm just testing my application to ensure all exceptions are handled gracefully, but I'm having problems with one particular error.
The code looks like this:
Code:
Try
fw = New StreamWriter(GlobalFileName, False) 'Open for overwriting
{stuff}
[Code]....
This code seems to catch errors such as the file being used by another process or whatever, but in the case of insufficient permissions to the directory (ie. 'read only') the code breaks with the error:
Unhandled exception has occurred in your application... Access to the path '...' is denied.
It is definately the "new streamwriter" line that is crashing it, but why isn't this particular error handled by the "catch exception"?
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 wrote an application to handle a joystick with directinput. It works fine if it uses the handle of the main window but it doesnt happen the same if the handle is the one of the component that contains the joystick's operation.
I mean:
main form handle: 15
component handle (which is inside the window and the joystick needs the focus of this component to work): 25
It always work if the handle i initilizate the device is the main form (15).How can i use only the handle of the component?

View 3 RepliesI am trying to get a handle on the correct way and easiest way to do things. By easiest I am not talking about being lazy just accessing and modifying later on. I have started using my own classes and such but I have a few questions. Sometimes I want to create a control on the fly through code instead of using the designer. Should I create this control in the main form file or in a separate class? If I make it in another class it seems harder to access later on. Then again if I dont know that the control is going to be created(user clicks a button to add a control) how can I access it? Also it seems alot harder to access certain things when it is in another class. For example if I create a new window in a class and then want to check if it is there or not it is alot harder to do.
