.net - Selective Recursive Component Recoloring In VB?
Apr 27, 2011
I've asked a very similar question before, but this time is not about VB syntax, but rather the best approach. I'm making a method that, when passed a component, will recolor it and all components contained within it. Below is the code I have so far, but it is not recoloring all components, instead only a mere few. My main problem is buttons staying in their "3D" styles and not becoming "flat".
[Code]...
The component passed is comp, and the getColor method looks into a database and returns a color corresponding to the part parameter passed to the method. This works for all low-level components and all simple components like labels.As you can see, this is not my preferred outcome. Does anyone know how to recolor spinners, buttons, and menu bars? Again, I need the button to end up being flat.

I'm trying to recolor all components in a form by using a recursive method. However, it always recolors the form and then stops. How can I make it go past this step? Here is the code I've been experimenting with:
Public Sub fixUIIn(ByRef comp As System.ComponentModel.Component, ByVal style As SByte)
Debug.WriteLine(comp)
If TypeOf comp Is System.Windows.Forms.ContainerControl Then

How can I choose which resources to compile depending of the compile constants used? So, if VAR1=0 then I wouldn't add RESOURCE_A to my final assembly.
I searched around, but didn't find any info regarding this... I guess I'm using the wrong keywords, since I doubt nobody else had this problem/doubt ever before.
Also, I use both VS2005 and 2008 at my job, mainly VB, although I haven't got any problem using C# either.

This is a follow up to my previous question: Filter DirectoryInfo files by date in asp.net
I have a gridview that is populating data from DirectoryInfo. However, I only want to display certain columns, and customize the column names and the hyperlink value in the row.
My code is:
Dim files As FileInfo() = New DirectoryInfo(strDirectoryPath).GetFiles().Where(Function(x) x.LastWriteTime >= (dtStartDate) AndAlso x.LastWriteTime <= (dtEndDate)).ToArray()
[Code]....
How can I loop through the columns, to display only "name", "extension" and LastWriteTime?

<DllImport("dwmapi.dll")> _
Private Shared Sub DwmEnableBlurBehindWindow(ByVal hwnd As IntPtr, ByRef blurBehind As DWM_BLURBEHIND)
End Sub
Is there a way to only load this if it is present? Only Vista/7 has this DLL generally, and if a program references it in XP there is an error.

I am working in VbExpress2008 with MsAccess as database.I have following code for transfer of data from Listview to table in MsAccess.
'To transfer data to the table Inventory

If con.State = ConnectionState.Closed Then con.Open()
Dim j As Integer
[code]....
My requirement is that I want to transfer selective data from listview to Inventory table based on ItemId. Like i have ItemId 1,2 3 4 to 32. I want that only data relating to ItemId 2,3,4 and 5 be transferred to Inventory table and the rest of data be transferred to other table.

I am converting an old Vb6 solution to .net 2.0 in vs2010. I've been working in C# for about 3 years now and .net for 5. I don't recall having this problem in C#, but if I want initialize a readonly collection of DerivedControlFoo Is there a clean way to do it besides creating a sub to do it all off somewhere else? I'd love to be able to do it at the class level at the declaration for readability and simplicity.

Create a DLL component for database operation and use created component in another project. Required methods, events and properties
a. Connect
b. Add
c. Delete
d. Save
e. Record navigation (first, next, previous, last)
f. Properties for all database fields
g. Events for validation of database fields.

I've created a component whose name I'd like to be able to change while editing in the component tray. I've added a Designer action for a name property, but now I'm stuck.
Looking at the property grid, I can see that the name property is parenthesised, indicating that it's not a regular property.

I am hopeing someone can help me here with a recursive function I have that is not returning either true or false as I would have espected it to. The function loops through a Active Directory group for its members and then calls itself if it encounters any groups within the membership in order to gets its members as well. I am trying to return either true or false based on if any errors were encountered but not haveing any luck at all. It appears to just hang and never return back to the primary calling sub that starts the recursive function. Below is my code I am using:

I'm a beginner to VB.NET. I'd like to make a simple backup program, and therefore I need a way to get a list of all files in a folder, and all subfolders. I've been searching the forum for "recursive file list", but it's too difficult for me to understand. Any simple way to get all files in a folder and all subfolders?

How would you put in that if a folder on the directory i'm copying from is, says, "windows" then to skip it?
Usage:
' Copy Recursive with Overwrite if exists.
' RecursiveDirectoryCopy("C:Data", "D:Data", True, True)
' Copy Recursive without Overwriting.

I'm making a program that can mark my shooting cards and i have created it and it works nicely But i want to get as much speed out of it as possible so I switched my target CPU to X64 and sure enough my recursive function threw a Stack overflow exception telling me i need to make sure i don't have Infinity recursions. Strangely when I set It back to X86 the same recursive function works...

I am currently creating a little application which will essentially backup my work I do at college. It works by me saving all my work onto a flash drive. When I run the application it will copy all the contents of the flash drive and copying to my college directory and when I'm at home copy to my Dropbox folder. This essentially gives me 4+ areas where my work is saved. Unfortunately, the college computers due to network restrictions and other problems, the use Dropbox on the college machines (I obviously can still access the website).

I have 3 variables. Lets call it "a", "b" and "c". These 3 variables can "independently" have 3 different values. Lets say: "1", "6" and "10". when you think of them as combination; there are (3^3) 27 combinations. I am told that it can be done through the recursive functions. However i am not a good developer to handle with that. Would u please help me?
- 3 variables and 3 different values are simplified. In fact; the numbers of variables and different values can vary.
- i know only the language, visual basic in .net; please don't answer in other coding languages.
additional note: i am going to put the these combinations in the string format into a collection.. for example "1;1;1", "1;6;1", "1;6;10".. and so on..

I have a recursive function wich objective is scan an structure and represent that structure with treenodes. Inside my function depends the structure I'll have to create another treenode inside my treenode or just create a node. My problem is that I don't know how to remember my treenode position when I have to call my function again.
If strTop.TextString.ToUpper = "DMN" Then
gcTreeno.Nodes.Add("Node")
Else
Dim perf As New TreeNode
gcTreeno.Nodes.Add(perf)
End If
if i would like to write next time a node into perf, how i could do it?

I have a MyList (List Of Longs) in which I need the check a specific relation between any two members of that list, if the relation-check returns true I need to delete checked member.I was used to do something like that with 2 For Next Loops, is there a better way. Would it even work that way with Lists?What is happening when an Item is removed from the List that has not been called by the outer For-Next yet? [code]
