I have written a Type Converter for a TrackBar. I was wondering if there is any way to get the value being changed in the Dropdown so I can update the PropertyGrid item value dynamically instead of just at the end?Here is the Type Converter code:
Imports System.Windows.Forms.Design
Public Class Slider
Private editorService As IWindowsFormsEditorService
Private m_Value As Integer

View 1 RepliesI changed my Username on my computer from i.e. "xxxxxx x xxxxx" to "Dennis"
VB 2008 during a compile gave me the following error: Error reading icon 'C:Usersxxxxxx x xxxxxAppDataRoamingMicrosoftVBExpress9.0VSProjectApplication.ico' -- The system cannot find the path specified.
The file "VSProjectApplication.ico" is in 'C:UsersDennisAppDataRoamingMicrosoftVBExpress9.0'
Somewhere in the VB2008 "configuration" files I believe that I need to manually change the old path to the new path.
I found the old path in the ".suo" file. The ".suo" file is not a text file. How can I edit the .suo file, save it so that it will work?
on my Form I have a DataViewGrid and some textboxes with a save button (they are filled with additional data of the selected row).Save is disabled first, when I change something in the textboxes the save button is enabled.When the user changes a gow in the grid, I want to ask before changing the grid row, if he wants to save (if the button is enabled).I am using RowEnter but this is too late, then the selected row already changed (and my textboxes already got new data)...What event can I use to ask if I should save stuff before the user changes a row?Something like BeforeRowChanging with a chance to cancel changing the row?
View 2 RepliesI have a list of servers in the first dropdown. I want to get list of all databases in the second dropdown depending on the server selected in the first dropdown.
For this I need to query each server while selecting the server.
I have 22 text boxes that have to be checked to see if the value has changed. I am using the TextChanged Event handler to do this thus:
Private Sub TextStringChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)
DataChanged = True
RemoveHandler ........
[code]....
The Handler would be added after the data had been loaded. The question is:Is there another way of checking for text changes without having to add and remove 22 handlers.
I am having a problem catching the event that happens when a user selects a value from a combobox. What I was using was ValueMemberChanged, but because I am populating the combobox in code during runtime using SQL and a dataadapter and dataset, this also executes the ValueMemberChanged event, so that makes it difficult for me to know when the user actually changed the value.
View 3 RepliesOk, so I am writing a program (you can check it out at and want to change the inputboxes to match the main form. Now, I know I could use additional forms instead, but I would prefer no to, as I would have to basically start over. So, I need to be able to change the backcolor and forecolor of the inputboxes (and msgboxes would be nice too). I am using 2008, and look forward to getting this figured out. Note: the website does not contain the code, but a published version of the program.

I am working on the Combobox.I was bind the data from Access database to Combobox in the DropDown Event.Now whn i click the Dropdown for selecting value , for one click the dropdown list is not showing. Some System is coming within few milliseconds it went out for second click the list is coming.This happens only whn i click the combobox first time in the form.After second time onwards the dropdown list coming properly.
View 2 RepliesGiven a datagridview, using complex binding I have a datagridviewcomboboxcolumn that displays data from a different table. My question is: when the dropdown list of the comboboxcell is shown is it possible to display a different text than the DisplayMember, lets say more detailed?I search for a solution but could not find any.
View 3 RepliesI gather MATTER NUMBER and PATENT NUMBERS in a listbox on a dialog form - that I pass to the main form after the dialog closes.I then ask for CASES on subsequent dialog forms and want to have drop downs for MATTER NUMBER and PATENT NUMBERS that "have the suggestions" of what was entered in those list boxes earlier.So - I've been using DATASOURCE for binding to datatables and thought to myself - heh - I can probably set the DATASOURCE of the DROPDOWNS - and it works!

i have a webbrowser and button,When i click a button i want it to select from a dropdownbox thats on a webbrowser.
HTML CODE
<select name="selopt" id="tpoles">
<br>
<option value="1">Yes</option>
[code]....
The problem is that all the values are "1"How would I make it select the "Yes" from it ?
I datagridview and I populate it using a bindingsource. I have the following code in the bindingsources PositionChanged event and it works as I want it to except when I filter the bindingsource.
Private Sub ProductBindingSource_PositionChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ProductBindingSource.PositionChanged
If (Me.ProductBindingSource.Current IsNot Nothing) Then
Dim dr As DataRow = CType(Me.ProductBindingSource.Current, DataRowView).Row
Dim ProductId As Long = CLng(dr.Item(2).ToString)
Dim ResultId As Integer = CInt(dr.Item(0).ToString)
GetReport2(ProductId, ResultId)
End If
End Sub
The scenario is when I click on a row in my datagridview the bindingsources positionchanged event fires and I load a crystal report. Problem is when I filter the bindingsource, even though the first item in the grid is now different the incorrect report is displayed because the bindingsources position hasn't changed.
I have a normal form (FormBorderStyle = Sizeable). When the user maximizes the form, the form's border should disappear and fully cover the screen. Like so:
vb
Private Sub frmVideo_SizeChanged(ByVal sender As Object,
ByVal e As System.EventArgs) Handles Me.SizeChanged
If Me.WindowState = FormWindowState.Maximized Then
'Remove border
Me.FormBorderStyle = Windows.Forms.FormBorderStyle.None
'Bring to front
Me.TopMost = True
End If
End Sub
Problem is, when the form gets maximized and border changed to None, the form doesn't cover the whole screen. The form gets the same height as when it is maximized with a titlebar on top. So, the form is about 20 pixels too short, leaving most of the Windows taskbar uncovered. So, apparently, if the FormBorderStyle changes after the form has maximized, the change in size is not corrected. How do I change a form's size when it's maximized or how do I change the FormBorderStyle before maximization is finished?
Ive got a datagridview, which the user can put in to 'edit' mode by double clicking. If they then make changes but click to another row, I want to msg asking if they are sure they want to discard then changes. If they say No I want to stop the selection change from being made.
Private Sub DataGridView1_SelectionChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DataGridView1.SelectionChanged
If edit = True Then
[Code].....
vb.net
Private Sub DataGridView1_CellValueChanged _
(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) _
Handles DataGridView1.CellValueChanged

I am working on a way to determine if the lines of a RichTextBox have changed.I currently use this
Dim newhash As Integer = Me.Text.GetHashCode
If newhash <> Me._prevhash Then
Me._prevhash = newhash
Me._lines = MyBase.Lines
[code]....
But this method has a bad issue: The text property takes a while to "load up" plus getting its hash code adds to it. This code runs every time the Lines are needed (it is a property). So this
For i As Integer = 0 To Lines.Count - 1
Dim line As String = Lines(i)
Next
Takes ages to complete, because for every line it checks if the lines have changed.I am trying to evade using MyBase.Lines too much, since that REALLY takes ages to load.
- I can not use the modified property since it is unreliable (set to true if only a text color changes)
- Can't use the RTF since it changes without the text changing (coloring) and the hash code is slow as well.
- Can't use the TextChanged event, since it is sent after the SelectionChanged event (for some reason)
Lets say I have 2 panels, lets call them P1 and P2... P2 is inside of P1...If I have a P2.VisibleChanged event handler it doesn't get fired when the panel becomes invisible P1 becomes invisible ... even though the .visible property changes???

View 4 RepliesI have a data grid on my form with 6 columns. 5 of the 6 are combobox fields. When just looking at the datagrid all the drop down buttons on the left really clutter up the grid. Does anyone know a way to hide the drop down button on the combo box until the time the user actually clicks in the cell. I have tried changing the style to flat which helps but I would rather it wasn't visible at all until the user is actually in the cell.
View 1 RepliesI searched "All Window Form" but I didn't find a thing which you use to select an item from a list by clicking on the selected item (like the thing you have to press on while selecting what Prefix you use when starting a thread). I guess it's easy to find, but I checked the whole list twice.
View 10 RepliesI'm trying to add a custom DropDown to the PropertyGrid for a control. I am adding the TrackBar control. It works fine, except, I would like to have the values updated in the PropertyGrid as I move the TrackBar. As it is now, it only updates the PropertyGrid when I finish and click off the TrackBar... I know the problem lies in the Type Editor. How can I get it to allow interim values to be processed. Is there some callback function I can use?

I have a ClickOnce app that has been working fine for a couple months, until a day or two back some internal politics borked the server. The result of this was that the path for ClickOnce during install changed just slightly at one intermediate level. It used to have /is/ in the path, and the is has changed to something else. I changed everything I could find, including recreating the whole target directory in IIS on the server. However, when I publish, though the link is correct, installation is failing. The log shows that, after checking and installing some prerequisites, the installation is attempting to go back to that /is/ path to find the app for installation.
Can anybody suggest where that invalid path is located? I have gone through every property I can find in Project|Properties, and they are correct. I have looked in App.config, and that is correct. Where else should I be looking?
I have seen it somewhere ages ago but cannot find the link... I want to create a custom drop-down "property page" like the one that pops out when you click on the down arrow in the property grid to set the anchoring.
