I'm just starting out with vb and am working on a single form project.
Basically I'm trying to take information entered in a textbox on the main forum, Appear in a tab control at the bottom of the forum through the use of a button.
As far as I can tell, I need to code the onclick button portion of it but am unsure about how to pass the information to the specific label in the tab control.
The below picture is generated by the following code:
Public Class Form1
Private Sub Form1_Paint(ByVal sender As Object , ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me .Paint

What I want to do is when I click on each grid on the form (Touch Screen), a tooltip of some stored information about the grid appears on screen. For example, if I click my mouse on square 6,8 then some stored information such as grid number, grid name, level...etc appears on the tooltip on the screen.
i have a form that I need to do two separate functions, however about 95% of the code is the same it's just that last 5% so I don't want to create two forms. What I would like to do is when I click on a button to open the form pass it a variable or something so I can determine which of the two buttons were used to open the form.
Basically if Button1 is clicked do this if button2 was clicked do that...

View 3 RepliesI have been using vb6 for a while, I am following a tutorial by MS to develop a basic application and a simple task cannot be completed for whatever reasons! The tutorial asks to drag the label object from the toolbox and drop in the tab control container. Then, go to the label size property and adjust the size to some different dimansion. Basic stuff, right? It won't let me do it! After I enter the new dimensions (which by the way are not large or very small), the label size (both width and height) resets back to its original dimensions! I have the vb.net sp1 installed.
View 2 RepliesI have a large number of labels which will be handling similar events and I don't want to have the redundancy of putting the same chunk of code into each sub. What I was wondering is if it's possible to pass the name of my label(s) to another sub that can use this label name to change the forecolor of the respective label based on its value. If so, I would would I go about setting up the sub?
View 3 RepliesI am in the process of prototyping a small sockets application, which monitors IT infrastructure (due to in-house financial and deployment restrictions, I am unable to utilise an existing commercial or open-source solution). Basically, I have a server application and associated agent process for communicating heart-beat data to the server. The server application implements a TCP socket class (TCPDevice), which is called from a WinForm. I am aware of the restriction on updating the UI from processes running on separate threads, and that the preferred technique for acheiving this is via the use of Delegates in conjunction with the Invoke method. Having had very little need previously for using Delegates (apart from of course std windows events and the BackGroundWorker control), I am at a loss as to how to do this in the context of my application, and would appreciate some assistance, although it has occurred to me that I could use the backgroundworker for marshalling updates to the UI.
Eventually the application will need to update a grid of devices via feeds from the defined agents, however for the purpose of this exercise simply updating a status bar on the UI will suffice. The section of the code which I believe is relevant to propogating the code to the form is contained in the OnDataReceived method.Below is a code excerpt from the protoype app which should put the above into appropriate context:

I want to (for an example) find out the computername of a specific computer. Now I already know the computers name, so I will test the result with the actual computer name, just to see if I am using the WMI properly.

I am trying to pass some information from a VB form to my MySQL database. i have named all the textbox's the same as the field in the database and checked all my database fields and textbox names which are all correct. When i try to enter information into a form I sometimes get an error at the .executeNonQuery section of the code.
To test, I outputted the SQLStatement string to a textbox ( which pulled through all the fields from the textboxes correctly) then manually inputted the completed SQL query into the database and it worked. But when I try to do this in one go it seems to fail if there is too much text ( if i enter 'a' into each field it works). Are they limits to the size of the SQL query that can be passed from VB?? all the MySql database fields are set to text with no size limits.

I am trying to input specific information on a form. I have created an sql statement from a table that will out put 18 rows of data. I have opened a recordset and instituted a do until loop. I need for the program to look at each row and if the Standard Score = the value of a field I have on the form it takes the value of the other three columns in updates it on the form. I have created the code and it works for upto 3 (Do Until loops)records, but when I try to add a 4th in the SQL statement and put in another do loop my computer runs it but it acts as if it freezes up.

I want to know how you can open a form with specific information as if you are just calling a sub, kinda like how a message box is. Example:
MyForm.Show("The form title")I also want to know how I could apply this to forms that are being created from pre existing forms. Exaple:
vb Dim NewMyForm as New MyForm("Title Text")'Now I want to know for each of these next 2 lines of code, think of them as being different codes all together.NewMyForm.Show() ' orNewMyForm.MdiParent = Form1NewMyForm.Show

I'm trying to grab information entered in textboxes. I'm trying to grab a name, an age, and a movie title from three separate textboxes, and put them into a single label like this:
"Name" is "age," her favourite film is "movie title."

I know it's a click event for the show button, but I can't quite figure out how to make the concatenated message.

View 1 RepliesI am wondering how I can select and pull specific bits of data from a block of information a user pastes into a textbox. For example, the information has fixed words and is always in the same format, but the numbers relating to the words may be different. One report might say, for example, Cars: 1.176 and another may say Cars: 863. How do I pull the information about the "cars" from a the block of text with the number value even though it can be different each time?
I must note that there are many many of these scattered throughout the average report and I need to pull the values of each of them in a single click, then paste those values into a different area on the form.
