VS 2008 Checkboxes Not Showing Correct State?
Nov 5, 2009I have a form that has many checkboxes located on a tab control with 3 tabs each tab has checkboxes on it.I have a button that when pressed selects all the checkboxes. That does work and it does execute all that were selected. However there are no checkmarks appearing at all. This worked before! It seems like the more checkboxes I added to the form the less they properly showed f they were checked or unchecked. Now none of them show unless I close the form and reopen it then all of the boxes are checked like they should be when the select all button is pressed.
View 12 RepliesItems In Panel Not Showing Up In Correct Location On Visible Changed?
Aug 5, 2009I have a number of textboxes and labels in a panel which has to scroll in order to view them all. The user is then able to scroll down and click on one of the labels which has a textbox that appears so the user can change the corresponding value in the label. For some reason, if the user has to scroll down at all to any of the labels that are initially out of view, when they click on the label the textbox appears far below as if it was at its initial position and not directly where the label currently is.

VS 2008 Serial Data - Make Sure The Correct Data Is Received?
Jun 28, 2009I am using Visual Basic express to create a serial interface to a multi-room audio controller. I have started by creating a form that can connect to the controller and I can receive data from the Controller and display Zone status, volume etc in corresponding texts box thaks to help from Stanav and Tassa in my previous thread.
My next problem is to do with receiving lots of data from the serial port and my application getting out of sync. This is mainly caused by turning the volum control as each time it is turned a little bit the controller sends out the new status of the Zone being effected
eg
****Turning Volume knob on Zone 1***
Status returned from Controller:
#Z01PWRON,SRC3,VOL05<CR>

Password Loop Textbox - Code Works To Read The Entry Data And To Recognise The Correct Data, And The Incorrect

That code works to read the entry data and to recognise the correct data, and the incorrect. However, even if entry is correct, the error msgbox will appear (x times of how many records there are in file), despite being navigated to the menu. Anyway that the Else isn't triggered when data is correct. Also for it to appear just one instead of (x times of how many records there are in file.)
Multiple Combo Boxes Showing Data From The Same Data Source?
May 10, 2010I have 5 combo boxes that need to show the same list of items that come from a single dataset table. I have managed to bind the datatable to the combo boxes no problem at all.. but when I run the application and select an item from one of the combo boxes all the others change to the item I selected. After some research I believe that this problem is something to do with using the one datasource so I have tried assigning the dataset datatable to 2 different variables and used them as datasources for 2 of the comboboxes but the same still happens.
A work around to this I can see is to call the same methods and SQL select statements 5 times over to get individual datasources for each combo box but this doing that sounds crazy to me. how I can get around this easily? Code snippet below shows 2 combox boxes and their datasources. I'm using VS2005, .Net 2
ComboBox1.DropDownStyle = ComboBoxStyle.DropDownList
ComboBox1.DataSource = AllergyListDataSet.Tables("ListOfAllergies")
ComboBox1.DisplayMember = "Condition"

Populating DataGridView With Correct Data
Jul 30, 2011[VB 2008]. I'm trying to populate a DataGridView based on information in the Items in a ListBox (specifically, the file names without hypens or file extensions) and the content of the actual files. The DataGridView is supposed to look something like this:
IDNon-Hyphenated File NameFile Data
1. Some fileThe sky is blue.
2. Another fileThe grass is green.
The Items in the ListBox (lstFiles) look like this:
C:UsersUsernameDesktopFolderAsome-file.txt
C:UsersUsernameDesktopFolderAanother-file.txt
What is happening is that the DataGridView is being populated, but it looks like this:
IDNon-Hyphenated File NameFile Data
1 Another fileThe grass is green.
2 Another fileThe grass is green.
It's adding the second file's information to the DataTable twice and not adding the first file's information at all.
Private Sub btnDoSomething_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnDoSomething.Click

Reate Articles In .NET And Save The Data To A Database With The Correct Html Tags?
Sep 9, 2008I am using the webbrowser control so I can create articles in VB.NET and save the data to a database with the correct html tags, allowing the data to be seen on a dynamic website. I have create a little menu bar with buttons on for bold, italics, etc. The problem is I have two webbrowser controls on and if I click on the first webbrowser I set in the gotfocus a flag which I use in the click events for bold. This means it knows which webbrowser to do the bold on. The problem is, first time round when I click on the first webbrowser it does not call the gotfocus event.

Arrays - DataGridView Not Showing Data
May 22, 2012I have looked around quite a bit, and nothing seems to answer my question in particular. I have DataGridView in which I add rows and columns dependent on a certain record count of geospatial data that is held in ArcGIS. The data is then passed through to the gridview for editing. So I do not use any databinding methods, rather it is a very manual process. I store data into a two-dimensional arrays, which indexes are based off of those certain data record counts. After the loops are complete, the data should be stored in each cell dependent on index. The very last row that was populated is populated perfectly, yet the other 72 (or so) rows are blank. Here is the code as follows:
