How can I read a textbox.text value when the textbox is not visible. This is a textbox that has been pulled on the form from a dataset. When it is visible it is fine. When I make the textbox.visible = False it no longer reads that value.

Basically what I want to achieve with this code is to read the text file and import the corresponding line to its textbox. But when i run this code BUT_A.text returns the value that is set for BUT_B on the textfile then any code after that doesn't import at all. Here's the code I am using for the open button (I'll be adding a OFD later)

Essentially what I'm trying to do is read a particular line of text from an integrated web browser (webbrowser1) into a textbox. The user will enter an id number into a textbox which will automatically search the online database search that will be open in webbrowser1. What I then want to do is read the resulting html text into particular textboxes.

I want to be able to read ONLY the link from the file.. In the first file above it would be after the "File1=" text in the file.. And in the other file it should be whats written after the "<ref href="" part..
And as you see in the second file there are three links, so to start with it should only read the first line, maybe later i could make a selection window popup or something..

Does a textbox have to be visible = true to get it contents in code? I am finding that if I make a textbox visible = false then there is no value there when I reference it in my code. I am using the Text property. Am I doing something wrong or does the textbox just have to be visible?

View 3 RepliesI have a CheckedListBox with 6 different indices that all correspond to a textBox. For example: Index 0 corresponds with TextBox1, Index 1 corresponds with TextBox2, and so forth. When the user selects the item in the CheckedListBox, the TextBox with that particular index becomes visible. I am at a loss. I have been working on this for 4 days now, with no end in sight!

Is it possible to have a Textbox on a form that when the user inputs data, ( during Runtime )that data remains in the Textbox for good and the Textbox then becomes read only ? Is it also possible to make it so that the CD with the programme on, is in the PC when the programme is being used. Perhaps writing the Textbox data back onto the CD ?
View 1 RepliesI've got a panel - that's in a group box. All of this - with lots of other textboxes on labels - is in another panel (the big panel).I make the big panel visible and not visible based on selections made by the user.This small panel - that's in the group box. I cannot seem to make it appear.Even if I leave it VISIBLE at design time - the objects in it will not appear.Is there some kind of nesting problem that I'm not aware of!
View 9 RepliesI have five menu items that i have created as a user control and placed on the master page. Now i want one of the menu items to be visible only for particular user role and not visible for others. Here is what I did. Its not working though.

I'm having an odd problem when making a form visible and not visible and it not continuing to function. Here is what I have happening. I have a main form (frmMain) that is an MDIParent. On this form I have a menu to open a second form (frmCalculate) and populate a listview from Items in the database.
As I click or select items in the listview on frmCalculate the tag is read and data is pulled based on the id stored in that tag and fills in various fields on the form. This works great. However, I also have a context menu attached to the listview that allows me to perform a "what if" scenerio on the items I am calculating. When I select this menu, I hide the frmCalculate and open the frmWhatIf form where I can mess around with values on the item I had hilighted in the listview on frmCalculate. Nothing is pulled from or written back to the database here, all the information is filled in from fields on frmCalculate. It just allows me to look at rising costs and how they will affect my margins.... anyway.
If I then close frmWhatIf, it brings my frmCalculate back by setting its visible propery to true (never closed frmCalculate, just hid it). At this point if I click an item in the listview I get an exception for a null reference. IF however I never hide frmCalculate, I can open and close frmWhatIF without ever having an issue. Why do I lose the functionality to select items just by hiding and unhiding the form? As a test I added two menus to the toolbar on frmMain one called hide and one called show. I then opened frmCalculate with original menu item to populate the listview and selected a few items to test that it was working and then using the hide menu I made the form invisible and the show button to bring it back. This yielded the same exception so without even opening frmWhatIf the problem still occurs.

View 2 RepliesI create an app, with it when I click a button it opens a new form on a second monitor.
This works perfectly, but every first time the app start and I open the second form, on my primary screen (right side) I see the border of the second form. When I click the button again, the form is hidden, and when I click it again, it appears again but then the border is gone. What I want is that the border is gone the first time and never appears.

Can someone clarify if there is ever a need for the below?
When setting a textbox "Visible" property to False is there any reason why I should also set the "Enabled" property to false.
How can I set my application in VB 2010 to do something when I press a certain key on the keyboard? I heard somethin about the Keypress Event but i'm not sure that will actually work. I want a code so that my application can do the following things: If I press either the left or the right Windows Logo key on the keyboard, I want it to make Label2 visible. I already set the Visible value on false in Mybase.Load.
View 8 RepliesI've got a program that runs from one Windows form, Form1, with stuff declared all in that class: public variables, public functions, subs, etc. I decided that the form was getting cluttered, so I added one button to bring up a new form, Form2, and I put some of the buttons & check boxes for testing over there, so that Form1 can be more visually clean. Problem: when I go to put the code for the tests into the buttons on Form2, none of the public variables or subs or functions that reside in Form1 are visible in Form2. What statement/s do I need to add (and where) so that the public "stuff" that's declared in the class for Form1 is visible within Form2, please?
