View 4 RepliesI have a wrapper class created around TextBox, and I want to find out if there is any way to test if the vertical scroll bar is at the beginning (the very top) of the text box and at the very end of the text box.Alternatively, I will be happy if only I can find out a way to check if a scroll bar is enabled or not in a textbox (note: it's not a RichTextbox).
By enabled, I mean that scroll bar is actually enabled i.e. you can use the scroll bar to scroll the control, not just visible (I know we can check visibility by GetWindowLong)
I'm adding a method to find and select text in my text editor. Everything worked fine, including the ability to find all instances of the text. My problem came when I tried to make it more user-friendly (doesn't it always?). Originally I had only a menu item with a shortcut( Ctrl + F) which invoked an input box.
Then I added a textbox and a button (similar to that seen in a web browser's Find() method) that calls the method in the same manner as the Find/Replace menu option and displays the desired text in the textbox. Everything works fine except that the text is not selected. I have MessageBoxes displaying the values of required variables in 3 places (marked ***FOR DEBUG ONLY***) to make sure that no values are being changed, but all variables are the same. The method still locates the text, but it is not highlighted.
I think it could have something to do with which object has focus. (When I click the button, the selected text loses focus?). But if I click everything with the menu items, it still works...

How can i find how many word in rtb1.text are same with tb1.text?
kinda like search...
you type in something like "hi", and it tells you how many times it has been used in rtb1 label1.Text = rtb1.Text.Contains(tx1.Text) 'the above returns - true or false - how can i do tht but with it actually telling me how many times it has been used??
I have a little question about txt-files...This is the case: I am going to make a small software for editing particular parts in text files, so you don't have to do it by hand. In this program, i need to find several words in a text file and retrieve the text or number that is after the the "="-sign, and then replace that info. Then, I want to use the information it retrieves to add some text in the end of the file.
P.S. There are 36 differet words to search for, and some of them will occur in several places, so i want the data from those words that occur several times in an array. And the data i want to retrieve is AFTER the searchword and a "=", so i dont want the searchword or the equals-sign included. Can someone explain to me how to do this?

When people use if statements on booleans, they either do this
if booleanStatement = true then
if booleanStatement then
I know that they both accomplish the same thing, but is one better than the other? Outside of 'good programming etiquette'

View 5 RepliesI would like to find text in a richtextbox. I know the code to find a string, but.My find button is in a context menu.I thought it would be a good idea (which usually turns out not to be so good to have a text box in the sub-menu. So, the person would click on "find" and the side menu would open (with the text box), one would then type the search string into the textbox and hit <return>, upon which time the search would be executed.I'm not sure how to implement it. I'm starting to think there might be several issues since the menu system opens the textbox automatically etc. How will I get the string since the textbox won't be "called" by the find button.Can anyone give me some help as to how to procede with this method, or if this method seems daft, then perhaps point me to an alternate or 'standar' approach for this?
View 3 RepliesI'm attempting to the file the user has opened and find the text the user searches for in a MsgBox.It works fine as far as finding the text, however if you the user will click cancel it will just say "Text Not Found".I'd rather just have the box close like you would expect it to instead of bringing up the box.

OK, Well I'm creating a "Card" creating app. The app will let you type in the name you want in the name field and then select a picture. But the problem is, is the saving. I want the card to be transparent like the original. The original is just a blank card. And theres a picturebox on the form that shows the original transparent image, and then a label over the name tag part of the original transparent image, and then another picturebox over the original pictures box for the picture, everything works for designing and it looks great after your done designing the card. But saving will not be transparent and it will not blend with the background.
How do I add onto the image and still keep the transparency of the original and then save it?
This is my code:
Label1.SendToBack()
PictureBox2.SendToBack()
Dim Card As New Bitmap(Panel1.Width, Panel1.Height)

I have a rather odd thing happening with an Excel WorkSheet that I am creating through .Net.I load up an existing workbook
Dim _xlApp As New Excel.Application
Dim _xlWorkbook As Excel.WokBook = _xlApp.Workbooks.Open(_templateFileName)
set it to be visible before populating it (for debugging purposes)
_xlApp.Visible = True
I then go on to populate the existing template.

Dim columnInsertPosition As Integer = 5

When i set a breakpoint on the "Private Sub Gen.." line, and step through the code line by line, it inserts a new column for each variable declared, so in this case it will insert two columns before it even hits the "If MyBooleanValue()..." line (I can watch it actually happen due to the Excel app being visible). However, if i dont set a breakpoint and just let the code run straight through this doesnt happen.There is no multi threading happening or anything else that i suspect would have any impact on the code.
I am wondering if it is possible to drag and drop a control, lets call it a button, and drag it from a FlowLayoutPanel and drop it in a diff FlowLayoutPanel?

I have a class that wraps up a few methods (e.g. OpenPort, SendMessage etc.). Some of the methods accept a number of parameters and return a value (e.g. SendMessage accepts port and a string that is the message to be sent and returns true or false depending on whether the mesage was sent successfully or not). I create an instance of my class when my form loads and I call the various methods throughout the lifetime of the app.In my SendMessage method there is actually a few steps that involves a delay as I send commands to an instrument and wait for a response. I'm using the AutoResetEvent class to synchronize things. Whilst this works ok I've noted that the UI is unresponsive during the wait period.
Public Class MyClass
Private _receiveNow As AutoResetEvent
Public Function OpenPort(ByVal portName As String, _

Hey is there any way you can tell a program to read things as a hex? so instead of reading AA as string read it as its Hex value.
Can you set it up as: Dim Reader As Hexadecimal or would this not work?
at my collage we have to rename all buttons and labels to represent the type of thing the button, label or text box etc do For instance if I had an OK button I would change the Text and (Name) of the button in the Properties section from Button1 to BtnOk, if it is a Label I have to change it to LblOk etc I was wondering if there is a way to change the default (Name) Button1 to (Name) Btn1 and so on so that I only have to click on the 1 and type my description, rather than having to type the abbreviation for the type of object every-time also ?
View 12 Repliesvbc.exe has something called /optimize switch right. If I enable that what are the optimizations the compiler can do for me? The MSDN documentation just curtly says 'does various compiler optimizations'. Where can I find the complete quantified view of the different optimizations that actually goes into.Here is the thing I am pursuing this route. One of the code blocks in a module I am leading has a lot of delimited array manipulations. I believe this is going to be a heck costly in terms of string memory handling. I am looking to see if I can retire them by way of simple properties or methods so that the compiler can internally do something like our c++ inline functions making a best win-win offer in terms of both memory and processing time. I admit when the compiler translates them as inline function, the JITed code might be big in size right?
