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.
View 2 Repliesi 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 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?
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 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 5 RepliesSeveral years ago, I created a nifty data entry form that is called from a main menu. Due to recent user requirements, I had to create another form that is very similar to the data entry form. To prevent duplicate coding and testing, I created a class to inherit the existing data entry form. The issue is when I leave the class and return to a sub menu, the class is opening the main menu and the sub menu. How do I only return to the sub menu without the main menu appearing? Here is a snippet of my code. You'll have to scroll down to the very bottom to see the section that is causing issues. BTW, I coded the application in such a way that only one form should be open at a time.
frmMenu (main menu). This is nothing more than a bunch of buttons that allows the user to perform various functions.If user clicks button #1, open the data entry form:
Dim objFrm As New frmDataEntry
bolOkToCloseForm = True
Me.Close() '--- close the menu screen

I have to make some automatization on a web server, I use Visual Studio 2005 Visual Basic Windows Console Application. I want to make a load/performance test of the web server, so I open several Internet Explorer instances, and I login the application, that is not a problem. But after that I have a mess on the page and I cannot make any more automatization...The composition of the page after the login is like this: I have the default form, another form and a multiple data window(mdw) controller, which dinamically can switches the forms on this part.
The problem is that I don't know how to access the controls of this mdw forms. I couldn't find much about this mdw controller and I am not an expert.
My code is here:
Imports System
Imports System.Diagnostics
Imports System.Web.Ui.Webcontrols

I have 2 forms. The first form has a label on it. The second form has a combo box, a text box, and a button on it. In the second form, when I select the label name that I want to edit, I type in what I want to change the label name to in the textbox and I click the button. Now this goes through flawlessly except I want the combobox item to change to the NEW label name. I've been able to do that but when I close the form in run-time and open it up again, the previous label name appears once again. Is it possible to make the combobox add the new label name and KEEP it in its collection?

I seem to be running into an issue. This may seem like a noob question (which it really is, I only have experience in vb6 from years ago) but what Im trying to do is pass a variable from one form to another. Ive tried telling the first form to set the value of the variable on the second form like so frmsecond.variable = "value" but that does not work. Ive tried placing a public variable in a module to do it, but again, no luck. The only way seem to be able to get it to work is the second form setting the variable by reading the value from the first form like so [code]The problem I have with that code is what if for some reason the selected line gets changed as the form is loading or something to that nature. It doesnt seem very secure.

<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.
