I have a word (2003) document containing many Activex textboxes which are used to apply a character limit to the users input. Sometimes users want to paste data into the textbox from another source ks fine, but if they try to do it via the Edit menu then the textbox is deleted and replaced with the pasted text
View 6 RepliesDo multiline textboxes have a character limit?Someone who was using my program said that he has some textfiles that are about 50 KB and when he goes to copy/paste that data into a multiline textbox, he only gets about 31.9KB of the data.My MaxLength property says 32767, which basically matches the 31.9 KB, however, most of what I read on the internet says Multiline Textboxes can hold unlimited characters and that MaxLength is actually ignored when a textbox is in multiline mode.

I am working on a sub that essentially needs to open a text file, and replace all instances of a certain character with a unicode character. I'm trying to do this by reading the original text file byte by byte, converting it to a character, and then either adding that character to a memory stream or writing the unicode character to the memory stream. Then I'm saving the memory stream to the original file.

I am programming in VB 2010 and have a question. I have some code that currently only applies to one text box. As you will see, I have sub setup to handle multiple textbox events. My question being, Is there a way to take this code and apply it to all textboxes that are being handled?
VBCode:
Private Sub TextBoxes_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles fnameTxBx.TextChanged, _
lnameTxBx.TextChanged, streetTxBx.TextChanged, cityTxBx.TextChanged
Dim theText As String = fnameTxBx.Text

I have 200 dynamic textboxes.
I am trying to limit the user input to exactly 5 characters ( not more, not less ), and numeric only.
I have been trying this :
Private Function txtValid()
Dim str As String
For Each txt As TextBox In Panel1.Controls

But it always shows the last messagebox. Not all 200 textboxes will be filled in, so I suspect that it may have something to do with that, but I just need to stop the user from entering alphabetical characters, and the entered field must have a length of 5
I have a big issue which I have been struggling with for days now. I have a richtextbox where users Can input text and print it.
My problem is that i don't want to allow more than one page to be printed so i need to prevent the users in inputting more text than what fits to one page.
I have word wrap set to True which means that i really can't count the lines since they are determined by number of return/enter hits. I can't set the character to a max because blank Lines and spaces Can cause this to differ very much.
What i really need i a way to prevent the users in inserting more text than would fit inside the richtextbox frame and the frame may not be resizeble.
I have a maskedtextbox that i want to limit character input in it but i can't manage to figure it out.The date type is "yyyy-mm-dd" and the mask is "1300/00/00" (it is not gregorian calender, it is persian )In the TextChanged event i am changing the bindingsource filter.Because of this i don't want the user enters invalid date. For example the user enters 9 in here : "1300/90/00" i want to prevent this from happening before TextChanged event occur. (the place isn't important i just want to stop user from entering an invalid month or day)I have tried the KeyPress event but i don't know how to detect where in the textbox user is entering a character.
Note that i know already how to validate and i have a code for that but the TypeValidationCompleted event occur when user does all changes and leave the textbox.

View 2 RepliesOverreaching amateur developer that is outsourcing some of my work and doing part of it as well. I've been working on a dictionary/ thesaurus / spell check & suggestion application that I am trying to get to work on all applications within the windows environment.
I've used hooking to get key stokes and show output as the person is typing for definitions and spelling suggestions. This isn't accomplishing everything I want. Works fine for spell checking and suggestions but to click on a word that already exists or for touch screen interfaces to touch a word it doesn't work.
I was reading the Raw Input API on MSDN and thought that would work but my developer that I've hired is advising me that the RAW input's scope is only on the window that has focus and so cannot do low level hooking. I'm considering giving the effort but wanted a 2nd third fourth perspective prior to making the effort.[URL]
I have an application where the admin user can create users and upload documents to the server for the created user to download.
When uploading a file it creates a folder using the userid as the folder name and saves in that folder within a folder called documents e.g. ~documents/77b29079-43d6-4520-bc34-77ae2af1b131/documentname.xls
The client then has to login and will see a list of available documents for that user only. The only problem is that if someone was to get hold of one of the urls to a document is can be downloaded without having to login.
Is there something I can do to stop access to these files?? I have tried editing the web.config file to only allow access to certain roles but i could still download a document without logging in.
