VS 2005 - Creating New Accounts And Saving In Bin File
Nov 15, 2009I'm currently working on a program to store files and information. I'm wanting the program to be able to have multi-user logins i.e. there are numerous combinations of usernames and Passwords. I've created a program that will create new accounts and save them in a .bin file (in the form Username Password). However, now I need to use the user accounts to grant access to a form.

Jun 4, 2011I am trying to use the BGW to save a DGV to excel file, but don't know how to do it correctly, specifically setting the savefile name this code doesn't work gives me:
'System.Runtime.InteropServices.COMException' occurred
- Make sure the specified folder exists.
- Make sure the folder that contains the file is not read-only.
- Make sure the file name does not contain any of the following characters:
Ensure that your Main function has STAThreadAttribute marked on it. This exception is only raised if a debugger is attached to the process. I also tried doing the Save in the BGW RunWorker Completed event but then there is no file name. It seems I need to pass the file name the user inputs in the SaveFileDialog to the BWG WorkerCompleted event somehow

Winforms Saving Images To SQL Server Without Creating A File On The User's Hard Drive?
Jun 22, 2011This is my first attempt at creating a Winforms application, and I have been developing in the .Net Framework (Silverlight, ASP.Net, WPF) for about 6 months. So, my appologies if this is a newbie question.
Basically what I am doing right now is taking the drawings of a stylus-based input, and storing them into an image field in a SQL Server database. Then, in another form, I go and get that image out of the database, and load it into a picture box. It works, but it is rather "sloppy" how it got there.When the user clicks save, it stores that image into a temporary folder, then converts it to a byte array and throws it into the database that way. Then, it deletes the file from the temporary folder. When retrieving it, it pulls it out of the database in a byte array, then converts it to an image in a temporary folder, thus displaying it on the form.
Is there a way that I can just bypass the storing of the file onto the user's harddrive both times, and go from byte array to picturebox?

VS 2008 : Creating New Checkbox In Groupbox + Saving Changes?
Apr 3, 2011I would like to use code to create a checkbox with default properties and place it at a certain position in a groupbox. For example, i would like to do this by pressing a button and that i can give in the name and tag by use of an imputbox. Also, i have noticed that if something like this is done, these changes aren't permanent and don't apply to the designer nor the code in VB. Is there a way to let the newly created checkboxes appear in the designer? And what about permanently deleting checkboxes by pressing a button. With "Dispose()" it isn't deleted from the designer...

Error Creating Directory And Saving Excel Workbook On Vista?

Sep 30, 2011I have a screencasting program where it takes 10 screenshots every second and saves it to a temporary directory then through ffmpeg the series of images are compiled into a video format. My problem is that due to the computers processing power or the size of each screenshot and its quality it sometimes takes longer than 100 Milliseconds to create one causing the whole video to be off balance. How can I ensure 100% that 10 Images will be stored?

Capturing Screenshots As A Windows Service?
Jul 29, 2009Basically I have created a windows service using VB 2008 where I am trying to capture screenshots periodically.
The timer is working fine and I have tested this.
The purpose of the service is to monitor the desktop over night when the user is logged off, by capturing screenshots and saving them to file. This is so admin can be alarmed about security breaches etc.
The problem is is that I have not found a way to capture desktop screenshots as a windows service (or otherwise) while the windows logon screen is active (i.e: when the user locks the computer). I have used google extensively but to no avail

View 5 RepliesTaking In-game Screenshots - Take A Screenshot - Either Comes Out Completely Black ?
May 1, 2012I'm working on a program which will allow users to take screenshots of full screen games, such as Call of Duty, Battlefield 3, etc. However, I'm having two issues with my code. First off, I'm having to press the shortcut twice, instead of once like my other shortcuts. This only occurs when the code below is actually in the handling sub. If I just have a messagebox show when the shortcut is pressed, it works every time. Second, whenever I take a screenshot, it either comes out completely black, or takes a shot of my desktop, even though there is a game running in the foreground. I have looked around, and it seems that printscreen is the only way to get a screenshot of a game through vb.net.
My code is below.
Private Sub game_Press(ByVal s As Object, ByVal e As Shortcut.HotKeyEventArgs) Handles gamewindow.press
Dim gamewin As RECT
If GetWindowRect(GetForegroundWindow, gamewin) Then

Taking Screenshots Violates Privacy / Data Protection Law?
Jun 9, 2009In my VB6 programs (internal to our organzation) I have always liked taking screenshots upon the occurence of an error to give me more clues as to its cause but somehow I have read somewhere that it may be in violation to some law (privacy / data protection).In the project I am currently developing and it will be for marketing I have used the same method but upon reading about the warning I am now somehow hesitant to use it although it has proved useful in the past.
View 16 RepliesUsing The Web Browser Control To Generate Screenshots Of An Intranet Application Developed In ASP.NET
Mar 21, 2012I am using the web browser control to generate screenshots of an intranet application developed in ASP.NET.
The screenshot is generated, compressed and then stored as a BLOB in the database. When I developed this facility I investigated the best way of compressing the image (to the lowest byte size), however the images still seem to be too big as the database table is growing larger than I hoped. I am using the TIFF format, but I am now thinking that this may not be the best as it is used by photographers (who I assume require good quality photographs). Here is the code to compress the image (before it is stored as a BLOB):

Does Express Permit Saving An Excel File As A Tab Delimited File
Dec 12, 2009I am creating a shell for a FORTRAN application which reads a tab delimited text file.Because I am using Excel to manipulate data, is it possible to use the Excel Automation features to "save as" a tab delimited text file?The only method available seems to be a unicode text format, which does not work. Or is there another format that mimics tab delimited so that the FORTRAN application will read such a file without difficulty?
View 1 RepliesText File Writer - Saving The File And Refresh The Page
Mar 9, 2009I have an asp page with vb.net code that will query a database and present the user with the number of records that exist that need to be exported along with a button to export them. After you push the export button, it will prompt for a location and filename. But after that, it will not refresh the page with the new counts that now exist. Or in this case update the count to zero for the button they clicked.
[Code]
So how can I tell the page to refresh with the new counts. It almost seems like I need to tell the process to wait until after the user has finished finding the location and saving the file but I don't want to add a generic threading.thread.sleep in, I want it to only wait until they are done and then refresh the page.
