VS 2008 Stop Textbox And Datagridview Cell From Scrolling (fixed Size)
Aug 16, 2011
I need to limit a Textbox and DataGridView to only enter text in the fixed size of the cell/textbox on the screen. So I have limited the cell/textbox so user can not change it size. Both allow multiline and wordwrap. cell/textbox is sized to accept 5 lines of data (wordwrap or enters) This is like an online form.So the text enter will be printed so I can not allow scrolling in the cell/textbox.
How can I stop the scrolling of the text inside the cell/textbox.
Also : if the user Paste into the cell/textbox how to truncate text if larger than display area.
sample settings:
DataGridView1.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.None
DataGridView1.AllowUserToResizeRows = False
[Code].....

I have just found that if a DataGridView image column's size (height & width - in pixels) is smaller than the image's original size (in my case all images are exactly 180 x 180 pixels) at the time the cell is populated then the image is automatically being converted to a lower resolution I assume to fit the image completely within the size of the cell). How can I stop the automatic scaling of the image?
The image below show the same file displayed twice, both at 60x60 pixels ('Thumbnail' column) and a blowup of the image (PictureBox populated via the CellMouseEnter event) to it's right. You'll notice the resolution of the first blowup is far less the the second. so, what made the difference in the resolution of the blowups is? In the second blowup's case I'd first stretched the image column's width to ~180 pixels and set the row height to match (via the ColumnWidthChanged event) then populated the DataGridView then stretched the image column to 60 pixels (its minimum).

I programmatically create a datagridview in my program. When the user first enters the datagridview with the mouse, the cursor changes to edit mode (thin vertical line) regardless of which cell is entered. I just want the cell highlighted (in selection mode I assume) as issubsequently done when the cursor is moved to a new cell.

Now all went well about from using the structure correctly. The working of the structure was perfect. How ever i missed Two important issues. The structure needed a fixed size of 10 items (9 in programming terms starting from 0) And also out of the 5 items allowed to be chosen as one of the member types for the structure a limit of 5 items of that particular type.

I have a label which appears full screen on a projector (VGA 2). In this label I will be sending strings. Some one liner's, some wrapped paragraphs. Some multi-line with carrage returns. My goal is to have the font dynamically change size to be as large as possible without overflowing the fixed label size.

I have a DataGridView with several columns. One column is a TextBox column named "Status". This column can only show one of three values: 'Final', 'Ready', or 'No Reportable'. I want to have some code that would turn the TextBox cell into a ComboBox cell when the user left-clicks on the cell to allow the user to choose one of these three options. When the user clicks elsewhere or the cell loses focus I want the cell to change back to a TextBox cell.
Here is what I have so far, but the code throws an exception indicated below Plus, I don't think the code would remove the combobox when the cell loses focus.
Exception: "Provided cell does not belong to this DataGridView control."
Private Sub dgvCalculatedResults_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles dgvCalculatedResults.MouseDown
Dim ht As DataGridView.HitTestInfo = Me.dgvCalculatedResults.HitTest(e.X, e.Y)

A program I am making required that I write my own code for column reordering rather than using the built in column reordering in the datagridview control. When I am dragging a column my code checks if the cursor is near to the right hand side of the control and if so it scrolls to the right using firstDisplayedColumnIndex.
The problem I am encountering is caused by the fact that when I do my custom dragging of columns the display index is changed not the column index itself.So when my code tries to scroll to the right using firstDisplayedColumnIndex once it reaches the very right it jumps back and forth. This only happens when I have moved the first column and thus when the first displayed column doesn't have the lowest index.

Im making a web browser (well I only want one page) but I want to stop the highlight scrolling, I've stopped the scrollbars and scrolling with the space key but highlighting still works. I did a bit of research and one said to put a transparent image over the top, but when I put a transparent background It turns grey so I can't even see the web browser.

So that's how I want it:
If I re-size the form, the textbox inside should be re-sized to fit the form, NOT DOCK!

Dim selectedRowCount As Integer = Grid.SelectionSettings.SelectedRows.Count
If (Grid.Rows.Count >= selectedRowCount) Then
While Grid.SelectionSettings.SelectedRows.Count > 0

above code throws me a "Collection was of a fixed size".

I have subclassed a control that would be vastly better if it was a certain size. At first, I thought I could simply set the height and width in the constructor. That would annoy people, as the control would be placed on the form at some size, and the size would then shift when the program starts, but it doesn't work anyways because the control constructor is called before the size properties are applied to it. Is there a way to fix the size of a control at design time? The only controls that I can think of that don't have the ability to be sized are pretty highly specialized.

Is it possible for a richtextbox to have a fixed size? For example, 5 would mean that the richtextbox would only show 5 lines at a time.

I am trying to create a function that will take a fixed value, and increment another cell. It does this until another cell using a formula equals the fixed value. You can see what I have below, but this is my first VBA programming ever so I dont know exactly how to declare everything.
Function meetMargin(Margin, calcM, nrc)
Dim x0 As Double, x1 As Double, x2 As Double, t1 As Double
t1 = 0.05
Do While t1 >= 0.01
x0 = Range("Margin").Value
x1 = Range("calcM").Value

I am developing, in VB.Net, an application that reads from text files using a FileStream Object. I do not use a StreamReader, since the buffering it does makes it impossible to use Seek.hose text files form a database, with both index and data files. In index files, all fields are fixed-length, which is not the case in data files.I've recently run into a problem. Since some of my files contain accents, the corresponding characters take more that 1 Byte. Therefore, when I seek in the index file, and offset appears the rest of my index file is not read in the right way

In languages like C++ and Java, it is possible to declare an array of an arbitrary size and then give it a specific size later in the code.

I have two forms in my program,on Form1 there's DataGridView and it shows the content of my database,on my Form2 there's few textboxes and listboxes. Wen you select row on Form1.DataGridView and double click the row header it pops up Form2 and shows the info of that previously selected row in those textboxes and listboxes.
Now with some help,i've managed to understand how to do that,but how to make those textboxes and listboxes connected to that row also?
I mean when i enter something in textbox it brings back the value to corresponding cell(to that cell of which value was shown in the textbox). Or how to make that textbox connected to the same row directly in my database itself(probably worse scenario,since any time i type new vallue and hit enter ir will connect to database,other way the value in DataSource will only be changed,it would take less resources and time probably?)

I have set a scrollable control's autoscroll to true. What do you do when you don't want a scroll to occur? For example, suppose you have a RichTextBox and a button side by side as below:
Notice that "button1" has the focus. If you click on the RichTextBox to give it focus, the scroll bars will scroll until the upper left corner of the RichTextBox is in view.
But what if, for whatever reason, you wanted to keep button1 in view? How would you do that?

I have a thumbnail control where I am adding Images using openfiledialog and after adding it automatically scrolls down.
So I would like to stop scrolling the scrollbar and just append the Images.
I have tried using this code:
Thumbcontrol1.VerticalScroll.Value=0
It worked fine but the scrollbar is at the bottom and it shows me the first row of Images.
And this is my second attempt by doing this way:
I have just set the autoscroll property to false and it hides the scrollbars and I'm stuck with this so how do I scroll the remaining Images?
And Is there any other method to hide scrollbars and just scroll the Images using mouse? Or any other simpler way to get rid of this?

I am trying to create and initialize an array of structures of a fixed size. Each struct will be populated when a button is clicked. Here is an example of my struct:
public structure buttonStruct
dim x() as Boolean
dim y() as Boolean
[code]....
In my form_load function I am declaring the array of structs and:
Dim BtnStruct(15) As ButtonStruct
BtnStruct(0).Initialize()
[code]....
Whenever a specific button is clicked, I am trying to collect data and store it in the respective struct and so for example, if button 1 is clicked then I will store the data associated with button 1 into BtnStruct(0). The position of the button is stored in a public variable called BtnNum. If I attempt to store information in the struct inside another function as follows, I receive an error
BtnStruct(BtnNum).x(pos - 1) = temp "btnstruct is not declared. it may not be inaccessible due to its protection level"

I have two datagridviews in my app. They're related. When there is no record in the parent datagridview, I select the "New Row" and then press the Add Button in the child datagridview's bindingnavigator. Then I get that exception:
InvalidOperationException: Item cannot be added to a read-only or fixed-size list.
I know why this happens.When I add new record to child datagridview, parent datagridview's new row loses focus and then delete row. So this error occures.How do I prevent my program from this exception. Remember, it's only occures if there is no record in the parent datagridview.
