Ok, 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 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?
1. create a button 2. when that button is clicked, an inputBox will appear to ask the user how many words they will enter. 3. then display an inputBox for each word.
For example, when the first inputBox appears, I enter "3" (meaning that I will enter 3 words).Then there should be 3 more inputBox (each inputBox allows me to enter only 1 word)After I enter the third word, there will be no more inputBox.How can we FLAG (stop) the inputBox, or let the inputBox know when to stop showing up?
Quick question on the InputBox. I am just learning this, what is the code to "read" commands that are placed from the Inputbox? I can do this in the command line: System.Console.Writeline(), System.console.Readline()
I just would like to know how read the line from the inputbox. Also when I debug my script do I -always- need to have the command prompt in the background?
I have created a users database in access and included that database in the bin directory of my project. I have then created a connection to that database using the wizard in 2k8 express.What i need to be able to do is to insert usernames into the users table in the database. I am at a loss of where to start with this problem. Do i need to create a recordset or not? If so how do i write an sql query in VB2K8 to insert data into that recordset and then update the underlying database?
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?
I'm making a program that uses a rich textbox and when you format the color of the richtextbox I want it to replace all instances of a color except black to have text on both sides of it.Example:If the text color is blue the text would look like this:
[color=blue]Blue Text[/color]
Where it says blue text that's where the text is blue. and if the text was red then instead of it saying color=blue, it would say color=red.
In the Solution Explorer window, is it possible to change the highlight color of selected items *when the form does not have focus*?For example, selecting a module in the Solution Explorer highlights that module's name in Blue, then when the focus is lost by moving to another window in the IDE, that blue highlight becomes a very, very light gray (on some LCD monitors in particular). I'd like to make that light gray a bit easier to see.Is this possible? I'm running VS2008 SP1 on Vista 64.
I'm basically trying to make a simple, easy-to-use, paint program. I seem to be having problems with using multiple colors in the PictureBox1_Paint option. It draws the graphics but when you change the brush color and click in the picturebox it changes the colors of the previous graphics to the color you are currently trying to use. I need it to allow multiple colors.
Here's the code that I'm currently using..
Imports System.Drawing.Drawing2D Public Class DynosPaint Inherits System.Windows.Forms.Form Private IsFormBeingDragged As Boolean = False
i'm making a "guitar pro" with vb. when i click a note on the piano, for example, the same note turns red on the guitar. so, i want to know how to reset the colors, because when i click on other note, the first one stays red...
I have a big datagridview that has a list of items, that have several states, every state has a date. My dgv will look like this:
----- Date1 | Date2 | Date3 ... It1 | It2 | It3 |
The same item can have multiple states in the same date, for example: The item1 enters the factory in the date1, and leaves the factory in the same date1, what i need it's that the intersection cell, have one line with the background in green with an F (means that the item enters in the factory), and in the same cell, but in another line (multiline) in the same cell i need another F but this time with the background red (means that item leaves the factory).
The usuals columns doesn't allow me to do this, i created a simple code to use a image column and then draw a image that does what i want, but i don't like the final results and it's a little slow, and when i select the full row, i don't have the usual selected cell visual effect in this columns... I was thinking to create a datagridview column with a different type (inherited) but i don't know what column to use as base column for my column, image column and then paint the content of another control in the cell or another type?

Is it possible to Insert text with different color in the same list box ? For example , the contents of the list box could be :Line 1Line 2Line 3Line 4
I think I'm starting to wear out my welcome by posting so much one after another..but, I'm having so much fun with this..Like a kid in a candy store. one more thing then I'll give you fellows a break. I was trying to get the colors and fonts to go into the registry and have the program pull those settings back into the program when its opened up but i can't seem to get it right for some reason. I only included the one line in the Form1_Load and left what i had in the in the other. Obviously this code is incomplete, and not functional As Is. So how do I save the Font Size, and then Save the listview backColor and Forecolor in the reg, and retrieve those settings when the programs starts?
I have a MySQL database which acts as a source for a datagridview, is there anyway I can set colors to the rows based on values in a cell? So that if the value in a row in the field "Priority" is "yes" then the row is red?
On Form Load I populate a menu with all possible colors so they user can pick a color. However when they pick a color the forecolor of my label is not changed.
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
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.
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
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???
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?
