I've got labels on my form using the following "Shift1Time1Label" to "Shift1Time8Label".I'm trying to get information from a access database and change the text of the labels.I'm getting the information, but having an "Object reference not set to an instance of an object" on the directcast to the label....

First, I would like to add a text box search field to this form (because navigating through several thousand users with arrows isn't going to work). When the search button is pressed, I want the username to be looked for. If found, the form (and each textbox, option button, etc.) is updated with that user. I can then modify the user's information and press save.
Second, how do I access and change information in a database with only code? For example, if I periodically want to check every user in the database to see if they have over "100 points" and if they do, I subtract 10 points from that user.
I have made a vb.net application which has 63 forms. On each form label2 should contain the username using the application. The first form displayed to the user is the login form. When the user clicks the login button on this form the user name in all newly opened windows should appear inside label2. How can I do this?
View 3 RepliesIf it is at all possible, I would like to print a page that is layed out with labels filled with text from previousley stored information from the program. now, obviousley, because the text can change in amount, and so the labels need to be able to change in size, and if at all possible allow multiple lines, though if there is no way to do it, then an unchagable text box would serfice.
There is a problem though, the fact that the labels will be changing size means that the position of the labels needs to be variable to the previouse. Example: the box above needs to be bigger, so the box bellow needs to drop down equall to the amount that the above grows.
I have a project with lots of forms in there with the default font property of Microsoft Sans Serif, 8.25pt
How do I change the font for all forms to let's say Tahoma, 8.25pt without changing it manually per form?
I have a program with lots of buttons and textfields etc in my main class (I guess), in the default on called Form1.
Aaand, I want to create a class, but can someone tell me how to change the text on labels and buttons from that other class, since the labels and such exsists in the main class?
How can i change two .text values of two label objects from one class?
I mean right now for me to change the text of two seperate labels i have two create two indavidual classes for each label to rename them.
But is there a way for the class, to change the names of both labels according to the class without having to create a seperate class for each label?[code]...
I want to change the text of two labels based on the the selected row of a gridview.I keep getting an error that says the public member row does not exist on linkbutton

Dim tour As Label = CType(sender.Row.FindControl("label2"), Label)
Dim depart As Label = CType(sender.Row.FindControl("label3"), Label)

View 5 RepliesI am writing an app to be a single button failover of a set of mirrored SQL servers. The app has to handle several other functions (enable/disable and start/stop of services, writing to local registry, copying files from server A to server B, initiating stored procedures, etc.)I have a collection of labels that indicate the status of 4 services on 2 servers, I wrote a function to check the services when passed the machine name, and the service name. Originally I just called the function 8 times (4 services, 2 machines) and populated the labels 'manually'. I have all of this within a timer so that the service status is refreshed every couple seconds. Id like to clean up the code to a single for/next loop that operates on 2 arrays (an array of service names, and an array of labels) such as:
'**Fetch_Status is the function that gets service status, it accepts 2 strings, machine name
'**and service name and returns status "running", "Stopped", as my_status
Dim Services() As String = {"Service1", "Service2", "Service3", etc.}
[code]....
The only reason I want the control array is to be able to use the .Text and .BackColor properties of the labels in the loop. If I make an array of strings with the label names it doesnt seem to pick that up.
im searching on how to change labels text color inside the code depending on my needs , for example my label's text is set to = "hello world" , can i change hello's world color to x and world's color to y?
View 4 RepliesI am working on a project that requires us to create a bracket type tournament and I am now stuck. I linked my access database to my project, and have 32 labels (lbl1-lbl32) and I cannot figure out how to integrate the labels to read from my database. It can be random or not, I just cannot get the labels to display the names of the fighters.
After the labels are integrated, the next coloum of the bracket has a link that opens a new window with each of the fighters match results, does the link have to include anything particular to display the attributes from the database?
in row or column..particular(one cell) should edit and change the information...and save to database...

I created a program that has serval labels on a form and a listview object. It has a button that when clicked reads a textfile and loads up values in the listview object. I then can click and drag text from the listview box to any label on the form and then the program removes the value from the listview box. Now, my question is how can I instruct VB to save these values in the text property of the labels so that the next time the program is loaded the labels will contain the values loaded during the last run time session?

View 3 RepliesI have been requested to implement a login form into a friend's Visual Basic .NET application. He specifically requested that I should do this using LINQ to compare the input to a table in an Access database. I don't really know why he imposed these restrictions, but who am I to judge? However, the problem is I am not overly familiar with VB .NET, or LINQ.
