Create A Folder And Dropping A File In It, With Area To Detect Input
Dec 25, 2010Make a folder, based on an input file - example :
You have a file named Movie1.avi on your desktop, u open up the program (that I want to make) and then simply drag drop that file into a box area, and then the program will create a folder, with the same name as the input file, but without the extension (folder name Movie1) and then automatically put that file into the folder it just created.
The new folder will be created in the same dir as the input file.
Multiple file support - is NOT needed.
I know how it will be done, but I don't know the code..

Detect Textbox Change?
May 7, 2012The Textbox_TextChanged event fires when a key is pressed or when text is pasted while cursor is in a text box.
Is there an event that fires on Textbox1.text="NewText"? How do I detect this?My reason for doing this is I would like to reformat text property automatically on assignment rather than do something like textbox.text=myreformat("Newtext").I can put code in validating or validated event but then I'd have to force focus/lostfocus to trigger one of those events.
Detect When The Cursor Is In And Out Of A Textbox
Nov 19, 2010I am new to Visual Basic and i am using VS 2008. I have a form with multiple (7) text boxes. What i would like to accomplish is basically, when i click on textbox 1 a predefined message would load to label1 and when i click on textbox2 label1 would now displays a different pre-defined message and etc... I've tried using the "focus" parameter of the textbox but it doesn't work. So i am thinking of using the cursor as a way to solve my problem but i don't know how to work with it. I found a very similar thread titled " Detect when the cursor is in a textbox/typing in webbrowser?" on this forum but i don't think it applies to my situation.

How To Detect Updated Textbox With Linq
Apr 19, 2011If this is a stupid question, then let me know. I can't just figure it out.First of all, this is my question. How do I detect the changed value on those text boxes?I have an idea that I create a another string values that have the original values and compare them right before saving or form closing event. This sample just have 3 text boxes, but I have 50 + text boxes on my one form. I can do it that way, but that is not really smart idea.Can I use abcDB.SubmitChanges() to detect any data changes on text boxes?

Accept Input For Textbox 1 And Textbox 2?
Jul 14, 2010I have two textbox controls and I want to accept input for textbox 1 and textbox 2. However, when user enters text into textbox 1 I would like textbox 2 to mirror the same text as it is typed.
I am sure this is a very simple procedure however it is new to me and I am having trouble finding an answer with search engines. Most result are coming back as text that one can read backwards in a mirror which is not what I am looking for.
Detect / Suppress Invalid Characters In TextBox?
Jan 5, 2012I have a TextBox with a list of filenames in it. The user is able to change these file names, but I don't want them to enter invalid characters, such as slashes or question marks.
I've tried two approaches, but they are not satisfactory:
1. Detect the key pressed with the KeyDown event:
Use e.KeyValue to detect keys like Keys.Oem5 (= backslash), then use 'e.SuppressKeyPress = True' to suppress the key.Problem is, with different Keyboard layouts, The Oem5-key isn't always a backslash.
2. Filter the text:
Use the TextChanged event and do a Replace("", "") on the text for every invalid character (there's 9 of them).Of course this will create 'lag' with every keystroke, especially if there's a lot of text. Also the text-cursor and scrollbar will jump back to the top-left when using Replace.
In short: I'm looking for a way to detect the character that is being entered and suppress or remove it when invalid.

Detect What Forces My Textbox Contextmenu To Close Soon After A RightmouseUp?
Jul 23, 2011When you you right click on a textbox the context menu is automatically open.
I have put a textbox inside a relatively complex user defined user control.
The annoing thing is that when I try to open the context menu with a rightclick the context menu is open but it shuts down soon after.
I tried to see if the mousedown or mouseUp of my (preview and not) usercontrol could interfere with this but i did not find anything.
Is there any trick that I can use to see what forces my context menu to close soon after is open?
Is there something in Vb2008 that allows me to see the steps widthout using breackpoints

This is what I have so far:

sErrorMessage = sErrorMessage & "-No more than 10 chars" & vbCrLf

The coding for the length works(is there a better way to do this)? The coding for the first letter to be A works but then I have no idea how to set validation for any proceeding characters entered. Am i right in thinking I have to find their position somehow in the string if so how?
