Mobile Web App - Handling Image Files Of Various Sizes
Dec 29, 2011
How should I handle image files of various sizes (<1 mb upto 15mb) within a mobile application that I am developing? Currently, I am displaying the image full size using a ASHX file inside of an ASP Win Form using the ASP Image Class. So basically what I would like to know how should I go about dealing with these sometimes vastly different image sizes. Would copying the image to be displayed and then scaling it on the server to whatever dimensions I decide and then displaying it in the browser be a better way of "handling" images especially in an mobile browser?

How do i center an image at all window sizes? My Window is borderless and maximized so its size obviously differentiates between resolutions. I'm having trouble centering an image directly in the middle of the screen and making it stay there regardless of the size of the window. Docking isn't working neither is anchoring and hoping there is an easier way around this?

I have a slightly unusual application that is optimally designed by doing the following. We have an application that references a number of graphic sets for unique artwork utilization. The application is in HD and the graphic sets are a bit large about 20 megs per set. We have found that the optimal design for this particular application is to create a unique .Resources file per set, compile this .Resources file into a .Dll file using Assembly Linker (AL.exe) and reference the .Dll via the application and load the graphics upon demand or selection actually of this unique set within the application.
Question is this as I have been unable to find any data on this aspect.
Is there a limitation on the number and size of .Dlls that a VB .Net application can reference?
Specifically, we will likely have 20-25 unique graphic sets reesulting in 20-25 unique .Dll files of about 20 megs per .Dll. On our deployment boxes for the applications, we have 2 GIGs of RAM so no issue there.
Just curious if anyone knows if I am breathing down the neck of an inherit limitation within VB .Net 2010 by creating the above monster.

in my application, to get the path I use the following code.
Dim path As String
Dim asm As [Assembly] = [Assembly].GetExecutingAssembly()
path = System.IO.Path.GetDirectoryName(asm.GetName().CodeBase)
this gives path as Application Data, But i need Program Files to locate the .sdf file. how to get this path?

writing code to read, write, parse, navigate XML files. Are there any good, simple XML developer libraries/SDKs for handling XML files? If you're familiar with the Kellerman FTP Library, that is the paradigm I have in mind -- i.e., add an import, declare an object and you have every FTP function you'd ever want, with simple syntax.

In VB6 you could BITBLT things around before refreshing the screen. In .NET, I'm aware of DrawImage, but that can only be done on a paint event rather than before anything gets painted. The issue I have is, I need to open several files with image data in them and then build a bigger image with those smaller images. Before I could open them, BITBLT them to a Buffer. As far as I can tell .NET offers no way to do this as the only function I've been able to find (DrawImage) only works within the paint event. Is there still a way to do this in VS08 or no?

I know this is out there and probably illogical but I was wondering if it was possible to take multiple picture files and compact them into one file.... and then retrieve them from the program later? Way to combine any amount of image files into one file
Module Module1
Sub combine()
Dim img1 As New Bitmap("i1.jpg")

I have written a VB .NET 2010 application which displays a "you have new mail" window/form with an OK button that closes the form.
Some users have received new PCs with dual-monitors and the OK button is no longer visible on the form - it's at the bottom but off-form.I guess that this is related to a different screen resolution and not the dual-monitor setup itself.how to make my forms auto-resize? I though this was automatic in VS 2010.

I have a basic VB.net app that displays a picture box with some text. nothing special. looks fine on my computer. If I display it on someone else's computer with a larger font size (125%?) my picturebox and text looks off and stupid.
How do people account for this? Should I simply get the new font size and multiple all positions, lengths and widths of object by 1.25?
I'd obviously like my dialog to scale properly and look as expected in any display no matter what font size is selected.

I have less than good eyesight now as my age increases :) I have managed to make most text areas/dialogs etc suitable for my eyesight, but can't find any way to edit/alter the Toolbar Icons - I expected to fin (at least) a seting for 'large' icons, or a way to increase/decrease the sizes - but so far I haven't been successful.
I find the icons/toolbars to be poorly designed in that they are on a grey background which just serves to minimise their effect.

Is there a way to make the actual tabs different sizes? I just want the tabs themselves different sizes not the whole thing. Seems like the itemsize property does this but it will only allow you to set one size. I want each tab to be a different size depending on its text.

Changing field sizes in database tables
I do it like this:
'First creating a temp table, temptabell, and copying data to it from table tabell
Dim strSql2 As String = "SELECT * INTO [" & temptabell & "] FROM [" & tabell & "]"
Dim dbCommand2 As New OleDbCommand(strSql2, cn)
[Code]....
This is working, this is how I did it in VB6, but I wonder, is there an easier way?
Would it be possible to change field sizes more directly?
