I have a SharePoint web part with a web-browsable property that stores a password. I've decorated the property with the PasswordPropertyText attribute but whenever I edit the web part it shows the actual password rather than dots or asterisks. Here is my property declaration:
i have this code in vb.net 2008 but i need it for vb.net 2003. Apparently, there is no passwordpropertytext in vb.net 2003.<Description("Password assigned to the User ID provided."), PasswordPropertyTextAttribute(True), Category("Database Connection")> _

It appears that my favorite thing in the world is tackling projects that are beyond my current knowledge and abilities. I have a little project that I am working on which is a simple image viewer stocked with (upon completion) your standard Load..., Next/Previous, Zoom In/Out, Actual Size, and Full Screen capabilities. However, I am running into a few snags:
(1) I've been able to get my "Load..." button to display a file dialog box, but I cannot seem to get a working filter (with which only image file types are allowed to be selected) in working order.
(2) I have a PictureBox object (entitled PictureBox1) that displays the image selected via the file dialog box, but it loads images in their full size (1:1/100% zoomed) state without scrollbars, etc. to allow me to navigate the loaded image. I would like to have it load the image, initially, to fit within the dimensions of PictureBox1 and from there be able to zoom in/out via my "Zoom In/Out" and "Actual Size" buttons and be able to scroll if the zoom level is beyond the dimensions of PictureBox1.
(3) It dawned on me that I haven't the faintest idea how to get my "Next/Previous" buttons to allow the user (me) to navigate, in succession, the images contained in the folder in which the currently loaded image is stored. [code]

I am moving over to vb.NET and am experiencing the learning curve. Am learning quickly, but I do have a question for anyone who can respond. vb6 could be made to run much faster by going after the GDI API directly, rather than going through vb6's standard wrapped functions like Line(), and Circle(). Now that I am working with vb.NET and GDI+, as far as I can tell there is no wrapper anymore and you hit GDI+ directly "right out of the box". Is this true? It looks like trying to phenagle the old vb6 API code can't work because .NET does not use GDI anymore...it uses GDI+ via the System.Drawing namespace.
I can't figure out why my addhandler is not firing?In the Sub "CreateTagStyle" the AddHandler is not firing when the LinkButton is clicked Is there some reason that addhandlers can't be added at certain points of the page lifecycle?

I have a COM dll that has been developed under vb.net. The Control works just fine in IE 6 and IE 7, but when IE 8 tries to load the control, the browser crashes. I look at the event viewer and I get an error 1000 about iexplorer.exe and mshtml.dll. Do I have to build this com dll with IE 8 on my development machine? How can I track down what is wrong with the Control?

I have developed an application is VS2010 ( VB app using .NET4 ) ... the application runs fine under Windows 7 and on (3) XP machines we have here. Had one user looking for support on an XP machine ... when he started the app nothing happened. No errors or anything, just nothing happened. Had him install the latest .NET4 framework and everything was fine.
Just had another support issue ... user with the same complaint ... had him install latest .NET4 ... but this time did not fix the issue ... still nothing happens when he clicks to start the app ... no errors ... just nothing happens.
I can't check this because it runs on all our XP machines .... Is the only criteria that .NET4 be installed? I created an install that includes only the EXE from the BINRELEASE folder ... nothing else. Do I need anything else. Strange that it works on all our XP machines.
my application required the dropping of resources when a button is pressed.It seems when this button is pressed on XP everything works swimmingly, however...
on windows 7 and vista the button simply dosent do anything, ive tried elevating to admin etc..
Is it possibly due to how it creates/drops resources?

I added a break point in this function but it is never reached, the above error message just comes up in the app. Any other ways to debug what's going wrong?
I have a CustomValidator that checks if text entered in textboxes matches certain fields in a database. This was all working great before, but I have modified my page quite a bit since then and it is no longer working. I didn't think I changed anything that would affect this, but apparently I did. All my other validators (required field validators) are working correctly, but my CustomValidator isn't responding.So anyway, here is my code:
CustomValidator: <asp:CustomValidator ID="CustomValidator1" runat="server" ControlToValidate="txtCoursePrefix" ErrorMessage="Course number is already taken."></asp:CustomValidator>
[code]....
Everything is working up until CustomValidator1.SetFocusOnError = True and args.IsValid = False. I have tested the If statement and it's working correctly, it returns true and anything else I put inside of it executes.

This is a petty issue, but I wonder why it isn't working.I assign a row number to each RowHeader in my DataGridView using the code below.
[Code]...
As you can see the row header width is the same. I have a lot of columns to display and I don't want my row header to be large. I'd prefer it be just wide enough to show the black arrow and number. In other words, I'd like to eliminate the space between the arrow & number and number & 1st column. Just like an Excel worksheet looks as you scroll thru rows. Is this possible?
I am a ASP.NET 3.5 web developer using VS 2008. I just started at a new company and there are alot of Web Designers here (never worked with Web Designers before). They all use Dreamweaver CS3 and PhotoShop (something i know nothing about).
What I would like to know is the following:Would they have problems opening my ASP.NET pages in Dreamweaver? ( I heard they might not be able to ).What about when i use MasterPages? Will they be able to open my pages when i use MasterPages, or must i stay away from MasterPages?
