I have a bit of a dilemma - in the ComboBoxColumn, I have added various numbers from 0 to 11. I need people to be able to type into the ComboBoxes in that column if the Combobox doesn't contain a value they need.I realise that I have to change the ComboBoxStyle to DropDown but am not sure how to. Also, for each row in the ComboBox, I believe I have to add the item that the user typed to the ComboBox list items for it to save but am also unsure how to do it.
I am using datagridviewcombobox column for the first time bound to a datasource.I have set the datasource, DisplayMember and ValueMember. The DGVcombobox is getting filled up from the datatable column content without any problem but unlike a normal combobox, it is not displaying the first item as the default text from its list.
So My question is how to display the first item, from the list as the default text so that the user don't have to select an item from the list for every row.
I am searching again and again but without any success, Please help me. Thanx.
I have one DataGridViewComboBoxColumn in the DataGridView, and that column's "ValueMember" is the "id" and "DisplayMember" is the "name" of my table. When I try to read the text with cell's "value" property, the "id" is returned instead of the "name". Is there a way to read the "name" or "DisplayMember" of a cell in DataGridViewComboBoxColumn?

I want to edit text, text in a textbox for instance, with vb code.For example: The text property of textbox1 is "Orange" When a user clicks a button, " Juice" will be added to the end of the string.So it will be "Orange Juice" Same thing w/ "Apple" Then it would be "Apple Juice"
I'm trying to create a text box that sends information to the registry. As an example, the user types "Value1" into the text box, and presses OK. The value in the text box (aka "Value1") goes to:
I have a simple in VB/ASP.NET form containing two text boxes, I am attempting to apply some validation to the first text box using JavaScript. This is the first time I have attempted this and am having some trouble.I have a label beside the text box stating an error, this labels visibility property is set to False. I wish the labels visibility to turn true if the text box is empty when the user loses focus.For this I have used the onBlur option within the tags of the text box. It then calls the JavaScript function and should set the label to Visible but it does not. I have tested to see if it is entering the function by using an alert instead and that works. The problem seems to be trying to alter the visibility property of the label.
Here is the portion of my code:
The JavaScript: function myRegEx(frm) { if ( boxUsername.value == "" ) { invalidUser.visible = True;
how to edit a text file that I have placed in a folder inside my application. The path to the file is "G:MyStuffEvolution_ Data_Extraction_v1Text Filess.txt" and I use a StreamReader to edit the file. However, once the file is edited, if I open the file in Microsoft Visual Studio 2010, the file is empty. Can anyone tell me how I can change? I also fear that once the application is deployed, the file path will no longer work as it will no longer be on my G: directory.Help Is A Click Away - http:[URL].....
How to select some (not all) text when editing ListView item, that is, if the item text is "Year=2009", how to select only "2009" when the user start editing the item text.
All right, here's my issue. I have a resource that is a text file. I'm trying to use a StreamWriter to edit it. I've done it in C# but can't find my example files.
I am trying to increase the height of a multiline textbox control so I can insert multiple lines during runtime. I want to go to a new line in my textbox after I hit enter. Also, simultaneously I am trying to generate a combobox next to each textbox line created by hitting enter. Here is the code I have so far:
I want to add nodes that behave in a similar fashion as when you add new folders in windows explorer. i.e. right click > new folder > then the new folder is added and highlighted as New Folder so that as soon as the user types they are overwriting the folder name.
I can add a new node as a child node of the node I have selected and label it "New Node" but I can't figure out how to select the new node and have it highlighted so that when the user types, they are overwriting the "New Node" text.
I have tried this but it doesn't work.
Private Sub AddProjectToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddProjectToolStripMenuItem.Click Me.trvProjects.SelectedNode.Nodes.Add("New Node") Me.trvProjects.SelectedNode = trvProjects.Nodes("New Node") Me.trvProjects.Focus() End Sub
I have a text file called: list.txt This is a list with all kind of lines like this:
14II_ARM_S_CLO_CLO_CLOVERIDS_PROPITEM_TXT_01194611IK1_ARMORIK2_CLOTHIK3_CLOAK=TRUE==200050000====PARTS_CLOAK=1==11=1===11_NONE Ofcourse every line has different numbers and letters.
The complicated bit is this:
I want to let Button1 check whats in TextBox1.Text and search "list.txt" for it. When it has got a match (there is only ONE of these numbers in list.txt).For example TextBox1.Text = "IDS_PROPITEM_TXT_011946". And I search for that so I find the line above. Now I want 3 other textboxes which show the 21st, 22nd, 23rd column/number after "IDS_PROPITEM_TXT_011946". And they should be editable by changing those 3 textboxes and clicking the apply button.How can I best do this, and please give a little example.
I'm new here and I'm trying to make a little program with Visual Basic (2010 Express Edition).The purpose of this program is:
1) Load the text file lines and split them into a constant and a value
2) Edit the text file lines values
The content of the text file is like this:
[Code]...
This basically split every lines in two parts: the constant ("Name", "Surname", "Age", "Hair") and the values ("Mario", "Rossi", "50", "Black").Now about the second point, I've added a Button1 which should take the Textbox1/2.Text and the Combobox1 selected item and replace the values(aka separator(1)) in the text file. The problem is I don't have any idea at the moment how to do it. What method should I use?
Public objword As New Word.Application objword.Documents.Open(FileName:=ofilename)
^ Showing the declaration of the word document that i wish to edit.
Dim oDoc As Word.Document objword.Visible = True oDoc = objword.ActiveDocument oDoc.Range.Text = codes(j, 1) & " " & codes(j, 2)
This gets the document and adds text into it, exactly what i want it to do. But it replaces the whole document. I just want it to add text at the start of the document. Not replace the whole document.

I have a datagridviewcomboboxcolumn which has its .DataPropertyName set to a int field, its .DisplayMember set to a nvarchar field and its .ValueMember set to a int field on a lookup table. I have captured a dataerror which states that the control is trying to push the .DisplayMember(nvarchar) to the .DataPropertyName(int) field. When I load existing data it works fine. When I try to leave the datagridviewcomboboxcolumn after selecting a different value in it or leave it when I add a new row, I get the error. What am I doing wrong?
