What is the cleanest way to assign a value to multiple variables? For example, how can I assign FALSE to each of Label1.Visible, Label2.Visible, Label3.Visible, Label4.Visible, and Label5.Visible.Is there anything like
code
Label1, Label2, _
Label3, Label4, _

This is my first attempt at writing a program that accesses a database from scratch, rather than simply modifying my company's existing programs. It's also my first time using VB.Net 2010, as our other programs are written in VB6 and VB.NET 2003. We're using SQL Server 2000 but should be upgrading to 2008 soon, if that's relevant.I can successfully connect to the database and pull data via query and assign, for instance, the results to a combobox, such as here:
[Code]...
How do I execute a query so as to assign each field of the returned row to individual variables?
i have a combobox and wish to assign multiple values if possible, eg is i select WESTERN EUROPE i would like the values to be: western europe OR western-europe AND Generic as the combobox is used to search for these strings within a listview (which is working fine for the combobox1.text but the listview sometimes has "western Europe" as "western-europe" and does not find it.

I have code, shown below, that works all except for 1 thing: The variables being passed byRef get passed, but once modified in the else section of the "if me.invokerequired" code of RecordData, the variables are never updated in the calling function. To reiterate, the calling function does not receive the updated data that is in the variables custid and amt.When debugging, I see the data change in the else section of "if me.invokerequired", but once it returns from the callback the data is missing.[code]

View 6 RepliesI have a table, the color of the whole row depends on one of the two columns. Table: | ID | Name | Date | Ext Date |
Where Date color depend on the value, <15 is green, <30 is yellow and >30 is red. While Ext Date depends on value, >-14 is red, >-30 is yellow, <-29 is green and without Ext Date value will follow Date value.
I tried to put Switch in IIf but returns no color at all.

Is there a way to give a value to multiple variables (integers in this case), instead of all at once?
For instance, I have Dim aceVal, twoVal, threeVal, fourVal, fiveVal, sixVal, sevenVal, eightVal, nineVal, tenVal As Integer and, pending listbox selection, I'd like to assign threeVal fourVal and sixVal all values of -1.
i would like to say i am a novice programmer, in year 12. I am designing a small game for my HSC and one of my forms is getting very cluttered with controls and code. To resolve this cluttering, i have had the idea to create new forms for some aspects of the game (such as different game modes and so on). However, in order for that to happen i have to drag some variables of the new form to the old form, (these variables would be just booleans or integers to say whether you lost a game or won a game or something that would carry on to the main form.)

I'm trying to set multiple variables using a textbox.The way I'm trying to do it is have each variable seperated by a space so like this:#If textbox1.text.contains("test") then set variables from textbox1.text for each " " in textbox1.text define new variable(value, string1, string2, int1, int2, int3, int4, int5)#End If I just don't know how I would code something that can set these variables from a single line of text in a textbox seperated by nothing other than just spaces.

I am trying to have it so that when a user hits a button to enter a shop, it will open a popup window which will have the shop's goods. The only problem is I can't figure out how to keep the variables working between the two windows.
I need to get the variable 'gold' to transfer to and from form2(the shop window) and whatever is bought at the store to transfer back to the main window.
Right now, when I go to form2 all the values are 0, and all the variables I used on form1 are undeclared on form2.
How do I access variables from form1 to show up in form2? Is there an easier way to accomplish this than using a separate form?
Is there any way to use a Select statement to Test multiple variables?

<pre-question blab>// skip if you want Might as well consider me new, as I haven't programmed in years, and that was only tinkering in Java. Trying to get back on track a bit, so starting with VB to get the feel going to continue learning. I don't mind putting in the effort to learn and look up, I just am not 100% sure what I should be looking into at the moment... Old programming I did was nothing advanced, only little things like calculators, notepad-esque writers, and that sort.</pre-question blab>
I'm BASICally wanting to know what I should look into for saving multiple variables of a custom class object to be loaded later. I've seen some things about text, and I can do that fine, but don't think it would be the proper/best way of handling things
at all. I also saw some talk of XML, SQL tables, etc. I just need a point in the right direction.
For a bit more info on my actual project, I was tinkering with a 'simple' program to allow users to create rooms/objects/etc., which will then be converted into Inform 7 language (an interactive-fiction language).The variables needing stored are objects with a number of string variables and integer variables. I need to be able to save those, then load them out later into an array of said objects.
For anyone needing a more VISUAL image of what I mean, here are a few screenshots to show you what I mean. Also, if anyone has ever used Adrift, it is (at the moment) very similar to it, but for the Inform language.

I have 10 forms and say 5 text box's on each one so a total of 50 of these text box's. But the program is only using one of these forms only (user selects the 1 Form out of the 10) so I was wondering can these forms Share the input text box's? I am thinking NO, if so then the only thing I can do is just use 5 shared variables that all the forms can utilize.
