Drop ImageFile On Demand?
Sep 8, 2009
i started using Visual Basic 2008 last weekend, and im still learning (ofc, i bet everyone can learn more that they already know about the program ) but still, i can make my own BinaryConverter, Spammer, TextEditor, Webbrowser...and so on But now i want to make something abit harder, i want to make a program that changes your Wallpaper on a button click.
Heres my code of the wallpaper change:
Public Class:
Private Declare Function SystemParametersInfo Lib "user32" Alias "SystemParametersInfoA" (ByVal uAction As Integer, ByVal uParam As Integer, ByVal lpvParam As String, ByVal fuWinIni As Integer) As Integer
[code]....
So, basiclly, this buttonclick changes the wallpaper to the file in path: "c:\picture.jpg" But i need to know how to drop a imagefile from resources down to this, or any other path. Otherwise it wont work, since the target dosent have the imagefile already on their computer.Ive tried out with this code:
Dim Location As String = "C:\Folder\file.exe"
My.Computer.FileSystem.WriteAllBytes(Location, My.Resources.File, False)
But this one does only seem to work with .exe files... and i need one that works with imagefiles.

I want to add an option to my windows form application (written in vb.net) that will give the user the option to hide the menu bar and the title bar. I can do the menu but i'm not sure what the best way is to hide the title.
I could just change the FormBorderStyle to none, but is that the best way of doing it?

I have made a login system for secure file storage. The way it works, is when you create an account it adds values to the registry containing the password and username. It needs to have administrator privileges to write those values, but not to read them. It would be very inconvenient to have to run as an admin every time, so I need to know how to require administrator privileges when the click the "Create Account" button, but not require admin rights when the program starts up.

Is it possible to reorder the elements of a drop down list (combobox) via drag and drop?For example, when the list is dropped down, I want the user to be able to drag the items up or down to reorder them. I tried this (and some google searching) but I'm wondering if its just not possible:
Private Sub cmbClassLists_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles cmbClassLists.MouseDown
If cmbClassLists.DroppedDown And Not cmbClassLists.SelectedIndex = -1 Then

I am trying to figure out a way to include the listview's tag field when dragging one listview's subitems into another listview. I am hoping someone here has experience with this. My Listview drag code is below - the two listviews that I am dragging subitems into or from are LV1 and LV3. Also, this is being done in Visual Basic 2008 and the project is a windows application.

So I made my form transparent by changing the transparent key to dimgray, change background color to dimgray. I also changed the picture box's BG color to dimgray everything was fine except that the drop shadow on the picture I did was just a grey blob.Is there anyway to make the drop shadow look like its a drop shadow?

Does anyone know if it is possible to make a drop down list control (when clicked) list its contents above the item, rather than below? Effectively, I need a drop up list rather than a drop down list...

drag and drop nodes within the same tree (not between trees) when users drag and drop nodes within the tree, give them the option to move the original node to a new location within the tree OR to just copy the original node in a new location (seems complex but I have a month to figure this out). change the system default blue highlight for selected nodes to another color change the system default cursors for invalid and valid drops (instead of the circle with slash indicating invalid target, i want a red minus) and (instead of the little plus sign with little box indicating a valid target, i want just a big green plus sign) add a red insert line to indicate where the node would be dropped within a tree also drag and drop the text of a node from the tree to a textbox add a "folder" image next to parent nodes and a "document" image next to children nodes
I have looked through the internet but I am having difficulty sorting through all the information available (I see a lot of information for Visual Basic 5 and 6, and those codes don't work for me in visual studio 2008). I can email anyone my code I have so far.

I want to be able to hold CTRL down to select multiple text entries and drag them all to certain text boxes. Or even one at a time, but once I try dragging another word into the box it replace the first one. Is there any way to just have it add to the text box rather than replace it?
And if possible, place a "-" between each entry?
This is the pop-up form with the listbox that contains the words to drag:
Private Sub ListBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListBox1.MouseDown
ListBox1.DoDragDrop(ListBox1.SelectedItem, DragDropEffects.Copy)

I have a small requirement and that is: There are two combo boxes on a form and for populating the employee names and roles. I am populating the combo boxes as follows: I have created a class called "DbConnect" and in that there are 02 functions as:
Public Function getEmployees() As DataTable
Dim employeeDS As New DataSet
Dim employeeDA As New SqlDataAdapter("prc_emp_list", conn)
employeeDA.Fill(employeeDS, "employees")
[code].....
The data is getting populated into the combo boxes correctly and my requirement is that when I select and employee from the first combo, his corresponding role should get selected in the second combo.

If you look at the source code for the html you can see the combobox has an id. However when i run a loop through all hte elements on the page in vb.net it comes up as a blank instead of the id thats clearly defined. I'm thinking it has something to do with the javascript giving it a dynamic id. Anyway. I need to set this box after the page has loaded in a webbrowser object.
<input type="hidden" name="wlw-select_key:{actionForm.dobMonth}OldValue" value="true">"
<select name="wlw-select_key:{actionForm.dobMonth}" id="dobMonth" class="dobMonth"><option" value="">Month</option>
<option value="01">January</option>

that didn't work either?

I am writing a small program that has two list box's which are populated from my sql database. I want to drag an item from LB1 to column1 in a datagridview and drag an item from LB2 to column2 in the same datagridview.
I am getting close, but I am having trouble getting the data to drop. I did some testing and I can drop a string, but I am not able to get the string data from my listbox. I just get a datarowview. I see the string inside the "itemarray", but cannot get to it.
Here is my dodragdrop:
LB_OriginalPallets.DoDragDrop(LB_OriginalPallets.SelectedItems(indexOfOldPalletToDrag), DragDropEffects.Copy)

I am trying to generate buttons and allow the user to drag and drop them.
I have this sub:
Sub Form1_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseClick
Dim nodebtn As New Button
[Code]....
Also if I declare the nodebtn as a global variable, I do not face this problem, the button is dragable. However when I click to add new buttons, no new button is generated, instead a button is generated with the count on it.

The best example is country and state. After user selected country, the state value should change accordingly.
I am still new in ASP.NET and I know in PHP it can be easily done using javascript.
May I know how to do it in ASP.NET using VB language?
