I'm new to the forum and new to programming with Visual Basic Express 2010.I would like to built a special calculator.Calculator will fall in number in the link provided on the website.
I am building an desktop app. In which I have to use a web browser. (with url: facebook.com) but I have a problem. This website runs in regular browser smoothly but in application it halts the computer and on and off I think it is due to heavy use of memory.
I am willing to extract value which present between double quote with special Chartres my current code is not working in this case, I am using string to get this value
value="fc6424b77def87f99ea2127eadbbc15f+"
Following is my code strKey6 = ExtractText("wpEditToken"" value=""", """", txt) key6 = strKey6
" So what i am trying to do is query from two databases and get results from both, but i want the querys to spit out a text file on my desktop, what imports or dim would i need, any help or samlpes, and i am wanting the code within the if statments below and then what i want to really do is stick in as a special format like so which i have from a previous person
I have a requirement of storing the following lines in a text file using VB.Net
<?xml version="1.0" encoding="ISO-8859-1" ?> <!DOCTYPE scenario SYSTEM "anup.dtd"> I am unable to add the entire line enclosing it between " and ". I have used the
I have a text box where users will enter 4 digits that are ONLY numbers 0-9. I have blocked all letters and less than 4 or greater than 4 digits. But, for example if I enter 10.0, it will throw an exception, due to incorrect math used later in the prog. So how can I block the use of a (.) or any special character for that matter! I am using specific msgboxes to let the user know what isn't allowed, and would like to do the same for special characters.
What I have so far:
If Val(txtEntered.Text) < 0 Or (IsNumeric(txtEntered.Text) = False) Then MsgBox("Sorry, but letters are not allowed!")
I'm working on a form in which strings of text are being imported. A lot of these strings contain special characters, like �, �, �, &, �, etc...
When I convert these strings to text, so they can be shown as labels, the special characters either disappear (like the '&' sign) or they are shown as some sort of icons. How can I let VB handle these strings, so the special characters are shown the way they should, without having to change the (many hundreds) original strings of text?
I have a program to read line by line from text file. [code]There is run time error while TextLine data has ' or "May I know how to read the data with ' or " character?
I need to be able to add (specific) special characters to text boxes. Problem is, there are five of them spread across two forms and three tabpages. What I'd like to do is bring up a form when the user presses something like "F2" while the text boxes are focused, then on that form would be a grid of buttons. When the user pushes a button, the character is added to the box. How do I get this form to reference the box that called it without passing a global variable or calling a public function? I tried Form3.Parent.Name, but that always seems to refer to nothing. Also, once this is done how can I get it to just insert a character where the cursor on the calling box is? It probably shouldn't even be on a form either since that will take the focus when it's called (which I don't want)
what i want to is convert this string to something like this
2. JXK2LB AP2WXB S1P0XE ZXPA3H X1LAKW DOXPS3
both 1 & 2 the above strings are fictitious (i made them up to make my point clear)
I am trying to make a licensing system for my VB 2010 express application. (2) above will act as a serial key which can be derived from (1) which is an encrypted form of something unique of the client computer.

How can I make my text box go to the enterd web address, through the user's default web browser?(And not by creating an actual web browser in the application..)
I have a TextBox and I want to allow VB syntax, but when I run the site and try to save the VB code to the database, I am getting an error. I believe the error has something to do with the VB code.I have put the httpRuntime requestValidationMode="2.0" setting in my web.config, and I've added validateRequest="false" in the directive at the top of the page, but it didn't resolve the issue.
In my program I want to add some values together with a running total, and then show that total in a text box. When I try to run it, though, it just shows zero.Here's the code I'm using
TotalPrice = TotalPrice + Price Next TxtLuggage.Text = TotalPrice
Something annoying suddenly happened with a text box in a self made program in Visual basic 2008. Whenever I try to run the program, this text box shows what is behind the program itself. (For example my desktop background) Not only that, if I click on it with the mouse, the window which is behind my application will pop up in front.
I tried to replace it with a new text box and a new name, in case I'd been messing around with some wrong properties, but the problem still remained.
I don't know why but text that should display in a text box, ALSO appears at the top of the form, where the title would be. Here are pictures of what I mean. The first picture is before the button to display the text is clicked. The title at the top is "Surrogates (20009)". The second picture is after the button is clicked and as you can see the text shows up in both the textbox and at the top.
I have a form used to display records read from a dB. The record fields are displayed in textboxes to allow editing. When the form loads, it reads all records from the table and loads the first record to the form - very straighforward. I set the Textbox.Readonly = True after loading the data. I have an "Edit" button that sets the value back to false so that editing can occur.
All fields display correctly apart from the first field textbox where there appears to be no text displayed. If I press the "Edit" button and set the cursor into the textbox and use the arrow key to move left, the text is there. In other words, the text is loaded to the textbox but somehow it is hidden. Now if I move to the next record the field information displays correctly. The problem only occurs when the form is first loaded and the first record is displayed.
Now for the strange part. If I delete that (first) textbox from the form and then re-create it, the weird behavior moves to the next textbox control and the first textbox behaves correctly. I have checked all the properties for the textboxes and made sure they are all the same. I have had this problem before and found the only way to overcome it was to regenerate the entire form again. Does anyone have any clues on what is going astray?
Ok I am trying to make it so that if words are found within the 'Textbox1.text' they will be delete or remove or completely not allowed to even be entered into the text box. I have found a code on these forums from a previous post which has worked for me
just ran into an odd problum with treeview node text I add a top node and I wanted it's text in bold. The bold works fine but half the text is missing
Here an example
vbnet Dim sFont As New Font("Verdana", 8, FontStyle.Bold) Tv1.Nodes.Add("TOP", "0123456789", 0, 0)
The code above for me only shows 012345678 and not showing the 9 any ideas if I use regular style it works fine only happens when I apply the bold style.
I've got an unbound DGV with several columns that I am programmatically adding rows to. All working fine, apart from when I try to set a really long string in one of the cells, then that cell just appears blank. The string IS in the cell because if I select the cell and do this:
[Code]...
then the string gets copied to the clipboard and I can paste it into Notepad or whatever without a problem. So it is just purely a display issue... but it doesn't seem to make any difference if I resize the cell (horizontally or vertically) and I can't understand why it is doing this.
I created a form using the TabControl and was playing around with the layout. I want to have the Tab and Tabs body to be transparent whether on that tab or not.
Now I changed the DrawMode to OwnerDrawFixed which gives me the look I want but unfortunately now the text disappears.
I have changed the fonts and colors of the text but when set to OwnerDrawFixed the tabs are all blank even though I have text written in the properties.
1. Is there a way to change the default white background for the focused tab without setting the drawmode to OwnerDrawFixed
i have an old VB6 system that generates plain text files. When this old system writes "A" into the file, it writes (hex) "41". For an "ä" (a-umlaut, special gernam character), it writes (hex) "E4".
Now i have to process files like this in VB.Net. when i open such a file in the IDE, it displays correctly "ä" (But not always!). To see what i mean, please open a notepad and create a new file "ae.txt" with content: äöü. Now your file contains exactly 3 bytes: (hex) E4 F6 FC.
But when i write code like Dim strTest As String strTest = File.ReadAllText("ae.txt") Debug.Print(InStr(strTest, "ä"))
i get 0 - so i cannot find back the "ä" - what do i need to do, to find it? And 2) for compatibility reasons, i have also to be able to create such files. How to do that? Seems the different encoding types do not work as i think.
I have Access 2007 db in which users insert some data (name, last name etc.). This db is for some problems in my work and every of this records needs some solution. When we solve this problem we come back to this record and select YES in yes/no field of db.I want to count inserted records and show it on first form of my application like this (label or text field, it is not important) :
* all records : 124 * solved records : 50 * not solved records : 74
