List Box Not Showing Database?
Jun 18, 2012I have two linked tables in my database (access), one is for the student and one is the ages(selection drop list ).
When I have transfered the data in vb form, a simple text box is shown with numbers in it. How can I have the drop down list shown with the data I need instead of the numbers?
MDI Child Not Showing In List?
Oct 25, 2010I currently changing an in-house Access Database to Visual Basic 2010. Since they are used to tabs in Access, I decided to use MDI Parent and MDI Child. What I dont allow is for the user to change the size of the Child. With that, I used a menu strip making one of the items [Open Windows] the MdiWindowListItem which worked great for awhile. Now I can not get any list to show no matter how many windows are opened. About the only thing I can think of that may or may not be the issue is I allow another MDI Child attached to the Parent from the MDI Child. Like below:
With newForm
.Text = formTitle
.MdiParent = Management
[Code]....
Even with removing this code to test it this caused it still had the same issue. I even went as far as adding a new menu and attaching it to the MdiWindowListItem with the same results.

View 3 RepliesTell If SuggestAppend List Is Showing In A Combo
Oct 28, 2009I need to be able to check from code whether the SuggestAppend List (not sure if that's it's proper name, I mean the dropdown that appears when you start typing into a combo whose auto-complete mode has been set to Sugest Append) is currently showing. Basically I'm looking for something similar to the DroppedDown property but applying to the SuggestAppend List rather than the Drop Down. Can anyone tell me what property I should be looking at?
The reason I need this is I need to do some work when a user cancels an edit in the combo by pressing escape. I've trapped the escape keypress but this only represents an edit cancellation if the dropdown list and the suggest append list aren't currently showing (otherwise the escape just closes the list).

View 8 RepliesMenu Strip Has Disappeared But The Menu Items Are Still Showing In Properties List?
Oct 6, 2011I have combed these forums and the 'net and can't find an answer to my specific problem. My menu strip disappeared (after deleting a small secondary form within my project). I therefore created a new strip and while recreating the menu items realized that the original menu items are still present, showing in my properties list. I have checked my design file as well and the original menu strip is definitely gone but the original menu items are there. I don't have many items so I would have no problem just deleting the original ones but I can't see them to delete them! I have checked and they are all set to visible. I have also moved everything on my form to see if it is behind anything else.

View 1 RepliesCreate A Toggle Button That Switches A List To A Range And Then Back To A List If Needed?
May 14, 2009II am trying to create a toggle button that switches a list to a range and then back to a list if needed. I am able to get it to do both but when I add an item to the list, convert to a range and then convert back to a list it leaves off the last items I entered.I tried to work in a code to select all cells but I must not be putting it in the right place.This is what I have so far:
ActiveSheet.ListObjects.Add(xlSrcRange, Range("$A$3:$AE$7"), , xlYes).Name = _
"List1"
I realize the problem is the $AE$7 (the $A$3 is correct)
DB/Reporting :: ODBC To SQL Server 8 Shows List Of Procedures But Not List Of Tables Or Views?
Oct 27, 2009In VS 2008, VB.Net, I am successful connecting to a local SQL Server (version 8) and seeing all tables/views/procedures in Server Explorer. The local OS is Win XP Pro SP3. I created an ODBC data source to a remote SQL server (also version 8) with a database of the same structure as the local one. The connection tests out ok. The remote computer runs Windows Server 2000 SP4. In the VS 2008 Server Explorer I add this ODBC source. When I click on the plus-signs to expand items, neither the tables nor the views show anything, whereas the full list of procedures appears. Is it the old SQL Server version? Is it the old Server OS version? Something else alltogether?

Determine If Property Is Generic List<of T> Via Reflection And Loop List Items
Oct 1, 2009I'm looping all the properties in an object via reflection:
For Each p As PropertyInfo In values.[GetType]().GetProperties()
If p.CanRead Then
'Do stuff
End If
Next
how to determine whether the property in question is a generic List(Of T)? If it is I need to loop the list itself.
I've experimented with GetType and TypeOf but have not managed to get anything working.
To clarify, I want to keep this generic. I do not want to specify the type of T, I need to loop the list items and call the ToString method on each item. T could be one of a number of different types (application specific reference types). Is it possible to do this without specifying types?

Shuffling Items Inside A Movie List / Need To Delete Half List
May 16, 2011Another program I am working on for fun, I am basically shuffling a list inside a listbox, what I want to do is delete the rest but not sure how to go through with that. At the moment I have this: [code] Just contains the code, declarations outside weren't included.So anyway, once clicked, it will call on the function to basically shuffle in a for loop, I was wondering if I should (or how should) create another function and call it in the click button or have just a loop in the click button so it deletes half the list. What I am doing is I have 20 list of items, I want the program to shuffle the items and then deleting the lower 10, meaning, if I had 10 items and wanted 5 top, I'd want: 0, 1, 2, 3, 4 and deleting 5, 6, 7, 8, 9.

VS 2008 Will Not Need To Update Each Component Variable Of Products List When Components List Changes
Sep 21, 2010I think (?) this is about object design, and perhaps about structural and/or creational patterns. But a bit hard to say when I only know a couple of patterns yet.[code]But... what if we INSTEAD want each Product instance only to (in some way) refer to one instance of a specific list of Components. So we wan't to save the products list to one file, and the components list to another file. Then would I build the objects the same way, or different? So let's then say we have now Class B as below. [code]
1. Will not need to update each component variable of the products list when the components list changes.
2. If the Product object shall be shown in a DataGridView, for editing properties, it seems easier to implement the selection of the component property.
Is this wrong approach? Is it suitable in some cases, and if so, when? Are there other solutions I perhaps am not aware of that would be appropriate? Is this about structural design patterns? and if so, can the alternatives above be catagorized to some pattern type? I don't really know exactly what I'm looking for.. But I think probably I'm looking to understand whether the object design will be determined by the way the objects are saved.. And if i shall save the objects by serializing to file, vs saving to a database, would I create the business objects differently?

[code] and if the idea of using list of list works how do i loop through both lists.
