Forms :: Using Variable As Part Of Control Name
Jul 25, 2009
Basically, I have a large number of text boxes. Within these text boxes, I'll be doing calculations based on user input and other things. These boxes will be grouped by numbers, eg Cost1, Profit1, Stock1... Cost26, Profit26, Stock26. Without too much explanation, I went to write a FOR loop to perform a repetitive calculation across multiple groups, and the following line came up.
FOR num = 1 TO 26
Cost(num).text = ItemCost
What I've tried to do is use a variable to decide which 'Cost' textbox, from the available 26, to use in the calculation. For whatever reason, it won't work. I would like to be able to use a variable to specify exactly which textboxes I want used, so that on the 3rd pass of the loop, the 3rd box is used, and on the 19th pass, the 19th box is used. Otherwise, I'd just have to do each calculation separately, and write the same thing 26 times, with slightly different numbers.

Is it possible to use a variable as part of a control name kinda like you would use a variable in a SQL statement. For example:
Lets say we have 4 text boxes txtP1Val, txtP2Val, txtP3Val and txtP4Val. Is it possible to have the P1 - 4 as a variable so it would be "txt + Some string variable + Val"

I'm working on a small accounting app. I have a query to show transactions with a running balance.
SELECT transactionid, transactiondatetime,
amount,
(SELECT SUM(amount)
FROM dbo.transactions as D1
WHERE D1.transactiondatetime <= D0.transactiondatetime) AS balance
FROM dbo.transactions AS D0
I capture a gamesheet for a certain week. so if I select a date on a monthcalendar the sheet applies to the weeknumber of the selected date. When I save transactions I take the date at the last day of that week as the transactiondate. I need to store a datetime though because my query works of the datetime to get an accurate running balance. How can I append now() time part to my date variable and then store that in a datetime variable to get a transactiondatetime.
Here is my code for getting a transactiondate:
Dim dt As New Date
dt = Me.MonthCalendar1.SelectionStart
'get last date of week. Friday
Dim tdate As Date = dt.AddDays(5 - CInt(dt.DayOfWeek))

I would like my forms to open as part of a "bigger" program, where there is a screen that fills the monitor and inside this screen is my form, centered. When a new form is opened, only the new form will be displayed...it will not be form on top of form.It would look similar to the screen in the following link, except the form inside the bigger screen would not have the minimize, maximize, or close buttons.I am just wondering if there is a property in VB.NET forms that will allow this to happen.

During runtime, while (hehe...pun ) doing some operations, part of my windows form turns white, and the buttons don't show, and it doesn't look so user friendly.I am running some processes and I wonder if If its because I am not using the process.waitForExit() function, and I have quite a number of loops...
I want my form to look normal, and preserve the user interaction and all, without whitening out.

I have a vb.net windows form app that I am deploying as using the visual studio deployment project. The app needs to write event logs to the application log in the event viewer. For reasons explained here I need to create the event source during the installation process. Something like this to run as part of the installer
If Not EventLog.SourceExists(My.Application.Info.ProductName) Then
EventLog.CreateEventSource(My.Application.Info.ProductName, "Application")
End If
That code needs to be run during the installer with elevated privileges. So my questions are:
How do I execute that code above as part of the installer? How do I get the installer to do the UAC prompt to allow that code to run as part of the installation?

I have a VBA form in Microstation I am using to try and help automate a task. The only problem I am having is I am reading a textbox (Filebox.Text) and setting it as the variable (FN). It works, because I used Msg.Box (FN) to test it. However, in two of the lines of code, I am trying to use (FN) to pass the typed in filename to the command to run in Microstation. Unfortunently, it gets passed on as (FN).dgn instead of the actual filenale typed into the textbox. Is there a way I can make the variable actually seen as a variable? Code on Pastebin: url....Also, not sure if this is the right section, 100% new to VBA, coming from a world Bashed together.

In my project, I have a form with a background pic that I like, but unfortunately, I also have a ListView on that form which covers most of the picture. Now, is there a way to find the part of the background image concealed by the ListView, and then display it as a background image of the ListView at decreased opacity? You know, like a vague image.Just one more thing, setting the form's transparency key to the background color of the ListView is not an option.

im making an application in vb.net (duh!) anyway i have created and coded the whole project and it performs exactly as i want it to (i dont need code help). my problem lies with the fact that my project is 2-3 parts
1.a setup form that gathers inital data about the enviroment stores this data encrypted in a config file. after inital setup this form is not displayed again. but needs to be run on both computers
2. the second form is the real application form im in the process of turning this part in to a background service anyway this form is the one that establishes the connection between two nodes it works correctly
3. the config files
anyway here is my problem i want to make this application distributional with just one file the (.exe) and have this .exe make everything else happen. it runs the setup form and creates the first config file which it does then it needs to produce a copy of just the second form and the config file to transfer to workstation #2 that will run independtly without the whole application which i cant make happen then it needs to turn both workstations application on by only starting one on either computer and invoke the other computer to start its corrosponding app also no idea how to make this happen any ideas or suggestions as to where to look to try to find my answers.im thinking i might need to make two seperate applications (a setup app, and the running app) and include them both in a project and use the setup.exe to to package them together this is a little side project that im making for my self to use to make programming a little easier so i plan on giving it out to some fellow students to test and tell me what they think so im not really worried about ease of use or complicated procedures yet but if it turns out to work and actually be of use to anyone else i would be willing to rewrite it to distribute to the masses but for now i just want it to work for me.

I'm trying to make a label control transparent over a Panel control.However by setting the background colour of the label to Transparent, it actually sees right through to the form itself, not the panel as intended.
As an example we use a panel with a background as white, we make the label transparent, however it gets the form�s colour as blue.However, we are using a custom panel control and need the label to be transparent over the panel and not see the forms background.

i have a splitter control on tab 2, a grid and a scheduler control on tab 3..looks fine...i save it....close the form...reopen the form, and the controls are all resized and moved around on me....and not for the better.
wierd thing is that when i run the app, the controls are placed properly, but design time is totally f&*ked up.I know this one isn't me. is it the tab control? should i just do toggle buttons at the top and show/hide my own panels? this is just too freaky to deal with. is there an easy work around for this?

I am trying to write a windows mobile prg with 12 static mileage points, form1 has the 12 buttons for start point, but when I call form2 with the destination points, my start variable value is not carried over. I intend to then assign a mileage based on the two points and write to file on mobile device. We support 12 schools, and I want my employees to track mileage easily.
Public Class main
Public start As String = "start"
Public dest As String = "dest"
Public miles As Decimal = 0
