I am "weeks new" to visual basic 2008 but I was hoping that someone might tell me how I can open an image in whatever type of "visible" graphics window (always positioned at: x=0 y=0); move to some "definable position" of interest x=(n) y=(n); change the brightness of that "individual pixel" by some "definable means of measure" from its original state; and save the new image as a separate image file?
View 4 RepliesHow do you change the cursor image to an image from the project resources?
The methods I have found either don't work or only change the image within the form, and reverts back to default when the mouse leaves the window.
means the images that will display in the picturebox is based on the value shown on the textbox (ProjID)..
Please see code below..

View 13 RepliesI have a listview control. it has an imagelist attached to it with two images in it. I have entered items into my listview, and they are using the first image in my imagelist.... GREAT! Now, there is a variable I have that will tell me which index in the listview is currently active, noting to do with what I select that could be at another index it's just what's being processed by the program at the time in some task.
Create a function that will change the images of all my listview items by looping through them. If the index variable is set to 2, I want the 3rd item in my list view set to use the 2nd image in my imagelist. The rest of the items in my listview need to be set to the first image in the imagelist.
so basically I have a text file that I read line by line now what I want is for each line to create a new picturebox with the image oww and on the text file, the lines contain image paths ok so after I get the images to show in a picturebox, I want each image to have a click event how can I do that
View 12 RepliesThe following code was working the other day. Now it isn't. When I type a character in the textbox the event doesn't fire.
[Code]...
why the event would just stop firing?
I'm trying to make it so this the cursor will jump to the next textbox after the user enters 1 character.
I am having a requirement in my project where User press '.' in his num pad and he wants the character ',' to be displayed (dats bcoz he is French User).
I tried changing the e.KeyCode but it is a readonly property.
Is there any other way to change the key in key events?
let say i have a function like this
' create filter
Dim colorFilter As New ColorFiltering()
' configure the filter

I have a dgv with several DataGridViewComboBoxColumns and when the user selects an item from one of these (product dropdown), i need it to repopulate another combobox (color dropdown) in the dgv for that same row - based on the value i get from the product dropdown. I've tried using the EditingControlShowing event; however, it only fires when I first select the dropdown .....?
Is this the right event I should be using? My other issue is that I don't know how to have the color dropdown re-populate for just the column and row I've selected. Here's my code so far for this event:
Private Sub DataGridView1_EditingControlShowing(ByVal sender As Object, ByVal e As DataGridViewEditingControlShowingEventArgs) Handles DataGridView1.EditingControlShowing
Dim myRowIndex As Integer = 0
[code]....
I can't figure out how to make it so that when a variable reaches a certain value, an event is triggered. For example if I wanted a user's level to change to 2 when he gets 1000 exp.
Dim level as integer
Dim exp as integer
*****What do I put here?*****(when exp reaches 1000)
level = 2
I am trying to calculate the 'Profit' field based on the current record's 'ProjectTotalBillingEstimate' field and the 'ProjectActualCost' field. I want the 'Profit' text field to be calculated every time a record is changed, either via the navigation toolbar or the Project ID drop down box. I tried performing the calculation everytime the 'Product ID' changed but then the values in the fields of the previous record were used. I was wondering if there was an event that I could use the would occur only after the entire contents of a record were loaded.Essentially what I need to happen is when one moves to another project record the profit field needs to be calculated only after all the fields update to the current record.

I have a VB project that is converted from VB6 to VB.NET.In this, I have a MSFlexGrid that is used as an interop compatibiliy. That means it is somewhat converted to .NET, but internally, many of the mechanisms are still from VB6/COM.I need to drag an image from a PictureBox (which is .NET) and drop it on the flexgrid.
This is what I do to initialize the drag:
Private Sub picStartSymbol_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles picStartSymbol.MouseDown
picStartSymbol.DoDragDrop(picStartSymbol.Image, DragDropEffects.Copy)
End Sub

I have a CollectionChanged Handler Method:
Private Sub LayersChanged(sender As Object, e As Collections.Specialized.NotifyCollectionChangedEventArgs)
If e.ItemCollectionHasNewItems IsNot Nothing Then
[Code]....
I cant call SomethingRelatedToE.excecute because it effects e's collection which causes a runtime error.
However if the LayersChanged method has completed I can then call SomethingRelatedToE.execute from another method without effecting it.
Is there a way for me to directly move to another method after the LayersChanged method has finished, like a Goto function or another solution to this?
Is there any way so I can get event when moving cursor in excel sheet. What I meant by that if cursor is in cell A1 then I move to B1 at that time I want cell change event should fire. At the movement I am able to get event when you change the cell value and press enter then I can get the cell change event.
View 1 RepliesI have created a form to update an access DB table. My issue is that when the text in the text boxes is changed and the form is submitted, the .text values stay the same as they were when the datareader loaded them on the page load event. How can I submit the values that the user updates, not what is already there from page load.[code]...
View 1 RepliesI hhave two modes in my application. Either of the mode is on at any part of time during the running of the application. I have given the user the option to create PicutreBoxes at runtime. Further, I have give two different options to the user.
If the first mode is selected, the Click event for the PictureBox is is pb_clikc and if the second mode is selected, the click event is pb_click_sp.
But the problem is that on the mode select event, I can't specify this line of code since picb is not existing in the current context.
picb.Click += picb_click for Mode1
or
picb.Click += picb_click for Mode2
i want to execute different subs at each tick , is that possible ?

I am working on a app that will monitor the registry for changes to [ProviderOrder] in [SYSTEMCurrentControlSetControlNetworkProviderOrder].
I have it 90% done with this
Imports System.Management
Imports Microsoft.Win32
Module Module1
Dim Watcher As ManagementEventWatcher
Dim Hive As RegistryKey = Registry.LocalMachine
[Code] .....
If I change [ProviderOrder.test] the app tells me the value was changed and corrects it. But it does the correction twice (because of UpdateProviderOrder changing the value). I thought that using RemoveHandler and AddHandler would take of that.
