I wanted to load a lot of items into the listbox and found out its limitation i.e I try to load 1000 lines of long words, it hit to the max. So my questions: Is it possible to bypass the max size limitation or is there other control that can handle better than listbox?

Is there a limitation to the size of program that you can create in VB 2010 express? I ask because I am writing a program that asks a user for input, then checks that input to a list of possibilities in case statements.My code is a little over 5000 lines.
View 17 RepliesI have both Visual Studio 2008 Express Edition and full blown Visual Stuido 2005. I create a simple Windows form that connects to an Access Database on both IDE's. I use the built in controls that are automatically added to the form to SAVE, UPDATE, and DELETE, and TRAVERSE records when you drag and drop a column from the dataset to the form. HOWEVER, I find that on the express edition when I click "Save" the changes are not applied back to the database!?! When I do the project in full blown VS2005, the changes are applied.
View 5 RepliesI am writing an app that includes the use of a NumberUpDaown control. I just stumbled onto what seems to be a 12 bit maximum limitation (FFF,4095). I've set the Maximum properties for 16 bits, 65535, but still see a 12 bit limitation. I suspect this is a MS limitation but I've found a description of this control which states it should be good for 16 bits.
View 9 RepliesI'm working with a form that doesn't want to let me go above 884 for height when I'm working in the editor. I thought I figured this one out before but my memory could definitely be better. I've played around with a bunch of properties without success.opping controls on the form and locating them below the bottom limit doesn't do it. The form will go down as far as necessary to show the new control when you run the application but not when I'm in the editor. I want to be able to work in the editor on a form greater than 884 height

I have wondered the solution to this question for many years! I doubt if anyone else knows much about it because the internet is absolutely zero help in this!
I have made a form1 with a webbrowser control on it. When the program is run it brings up the homepage (which is Google). However the homepage doesn't seem to fit inside the webbrowser control.
So I am hoping that someone could tell me how to make the (...I dunno how to ask this retarded question...) webpage fit completely (100%) inside the size of the webbrowser control. Meaning...I would like to see the entire webpage from the internet in the
size of the webbrowser control. To fill the entire size (whatever size I want).
Etc... if my webbrowser ontrol is seh, set to 600px by 400px, how can I program this so when it brings up the homepage (or any other page), it fills the entire size of the webbrowser control? Without any scrollbars. How to make the contents from the web
(or local) fill the size of the webbrowser - almost like a mini browser if you will.
I developed a form application on my computer, but when it was used in another computer with different screen size, i was told the form didn't fit. Do I have to adjust the form size or any other ways to let the form compatible on different screen size? (could be different screen size or wide screen)

If I re-size the form, the textbox inside should be re-sized to fit the form, NOT DOCK!

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.

View 3 RepliesI have inherited from a Windows.Forms.Listbox so I could override the OnPaint and OnDrawItem methods in an effort to highlight specific items and alternate backcolors. I am also skipping some DrawItem events to prevent flickering.Everything is working fine, however when I select items in the listbox, it looks like the font is shrinking or becoming more compressed.Then when I mouse leave, the font goes back to its normal size and appearance but the same items are still selected (which is correct). During debugging the font never changes nor do any of its properties, but it does end up looking different when the item is selected and the mousedown event just happened.

View 1 RepliesVB6 application MDI-Child architecture. Closing event is handled via QueryUnload event in both MDI and child form. Order of event trigger is MDI form closing(QueryUnload) event fires first followed by child form closing event(QueryUnload, I would like to call it as FormClosing itself as it is more comfortable and correct)Now after migration, order of event trigger is occuring in reverse. Child form closing event is firing first followed by MDI form closing event. We want to reverse the event triggering badly because of the logic written inside the closing events. Swapping the logic inside the events is not a viable option considering the huge changes we need to make (we have 31 vbprojects with 31 MDI forms and numerous child forms).
How I can make the MDI's closing event to be triggered first before child's closing event?
