I have a form that I will be using to keep track of data for computers I build and will eventually link into a database for configuration management, but for right now I'm just trying to get the basic form layout done and functional. I need this for to be customized for each job I do, that means I can have multiple computers, PC card, peripheral equipment, etc. So with that said basically what I have done is created a user control for each separate item that I want to add (i.e. computer, PC card, etc) that has all the fields and functions I require. When I want to add another computer I just add a tab and place my "computer" user control on it, no big deal...
My issue is when I want to add my "PC card" user control to that "computer" user control. What I am trying to do is to add the first user control(PC Card Info) I created under a button called "Add New PC Card" (which is part of the "computer" user control.)and that part works! What I want to do is keep added as many "pc card"user controls as I need and basically keep appending them under the last control on the bottom of the page (which is the "pc card" user control, that is a groupbox with a few drop down boxes and text boxes in it.)with a little spacing between them. The biggest problem I am having is when I add the first "PC Card" user control, it works.. but when I try to add another one and search the current page for all user controls under a certain point or with a specific name, I don't get any results.
I think I'm on the right track with the following code but I am running into 2 things I can't do that are critical to my needs. 1: I need to define the text of the user control I just added so I can uniquely identify it, so If I need to remove it I can and will also play a role later( I thought if there was some way in code to make my control # a variable that may work) 2: I need to know what to look for since I have a count that represents how many of that particular control exist on my form, that way I can name them properly, this will also allow me a method to delete the user control if desired.
Dim pccard As New PC_Card
Dim x As Integer
Dim name As String

I have a vb.net web application and when a particular function runs , i get data timeouts in the rest of the application..(ie..row not found errors or column does not belong to table but it does) The function is adding multiple rows in multiple tables in the database and is running in a for loop. It seems to be all SQL related but I am not seeing anything in the error logs in SQL or in the application Right now I am assuming it is memory related where to start note..the for loop will be replaced with a bulk insert but right now I jest need to resolve the issue of the timeouts
View 1 RepliesThis question is about VB.NET. I'm quite a novice on this one, so please forgive me if you feel that this question is nothing short of crazy or whatever. Anyway, I've been a creating a simple Windows addressbook Form application. We all know for a fact that a single person can have one or more addresses, of which a one-to-many relationship holds true. So there, my application also has to be able to edit each of these addresses (by the way, my application uses an Access Database, which really sucks but it's part of my task), and I already thought of using a control array (just like in PHP but it obviously never worked in .NET) for me to edit them. How am I supposed to implement this?
View 3 RepliesI have some questions on AppSettings. I can add a setting at design time from the settings tab of the My Project. I would like to add to the settings at run time. I have not found a way to do this. I would in VB6 use an ini file but would like to start using xml.
The .net makes this folder for the settings C:UsersRyanAppDataLocalTestAppSettingsAppSettings.vshost.exe_Url _0ay3fimqt4k0pp1s2e4vb3pi3iymxzx2 .
How do I retrieve the location to add to the xml file?
I want to place a few buttons on my form. The number is unknown at design time. Actually each button will represent an item entered in combo box. So if user adds an item, a button on the form should be added by the code.

View 10 RepliesI have added a DataGridViewComboBox to my DataGridView during design time. It has 0 items in it and I need to add a bunch of items to it during runtime.
In most controls, they have some kind of direct method like ".Items.Add("etc")", but for the life of me, I can't figure out how to access the DataGridViewColumn programmatically.
I can create a new ComboBox during runtime and add it to the DataGridView, but that's not what I need to do.
I played around with IntelliSense, I've searched on Google and I've looked through the documentation. The only thing I could find on MSDN was DataGridViewControlCollection, but I didn't see anything that would allow me to directly access that control.
I was writing a program for creation of form to ticket reservation. The form creation and everything is done a runtime. The problem is that i wanted to include a validation process in which the program will check whether user has entered the data(name) before showing select airline list box There are 2 if conditions which i both want to validate and if both the IFs are validated then i want it to show the list box.I dont know how to do that. Below is the code snippet

If (t1.Text.Length <= 3) Then

In the helpfiles of Visual Studio 2008 I read control arrays are no longer supported. There is an example for the new situation but then you need to hard code the names of all the controls beforehand.I do not know how many controls I need, could be one or 5000 (think simple image browser). Is it still possible to create something like that or should I change to a different programming language like Phyton? At the moment I work around it by using a browser control and then manipulate the <img> tags but I'm puzzeld as to why this functionality was removed and if there's a solution to the problem.Another thing I don't understand is where the app goes when it's installed with 'Click once'. It dissappears completely, doesn't show up in 'Program Files', can not be found by the search function but it *is* somewhere because you can start it form the Start menu. However, I use data which is in a subfolder of the program folder, which I nor my program can find any more after the app is installed. The program runs but it can't find any place to put/get its data so in the end it doesn't work.
I work around it by *not* installing the program but have people just run it after unpacking the downloaded folder. This works great but I wonder how long this will be the case until Microsoft disables this possibility? I have no idea why they would, but I also have no idea why they did remove the functionality I mentioned above. I already changed to PHP and MySQL because I had to throw away my carefully built W2K+MSAccess image database a few years ago and after installing Vista Visual Studio 2005 was a goner. OK, I upgraded but then no control arrays any more and now they hide the apps when you install them? Why on earth would they do that?
I have a basic IDE for a user control i am building. It allows me to add labels to a panel and move them around, like a very basic form designer. When I add the controls to the panel at runtime, I'd like to give the control a unique name string like how the VS IDE tracks the controls it already has and adds an extra number when it creates the default control name. I have tried checking the controls collection each time a new control is added, but wasnt sure if there was a good string comparison method to return a name with a unique number on the end that hasn't been used yet.
View 2 Repliesi am in runtime mode and have a form open. I do some calculations on it and based on those i generate some lines of VB code (concatenated and saved in a local variable). Is there a VB command that i can use that will take this code and INSERT it into another form?
i could copy the code, exit runtime, go to design mode and paste it into the form myself but because i want to do this for several subs for a lot of forms then it will become very time consuming.
I am very interested to see the answer as I would like to know the significant differences (if any) of generally using one more than the other. In a few days, I will be starting my Java programming class to familiarize myself with the language.I do know that Java uses objects.My question/discussion is not necessarily related to .NET (although in a way, it is); my question is more about what is a better practice and why.Is it more proper to declare buttons and such through runtime rather than designer? Is it just more work typing everything? Or does build and run much faster?

Any snippet of code for adding groups at run-time to a listview. I am currently listing books (and stats) without groups via the following code which is executed in a loop (one pass per book title).
item = New ListViewItem
item.Text = seq.ToString
item.SubItems.Add(Mid(titlenode.Nodes(N_CSTAT).Text, 3))
item.SubItems.Add(Mid(titlenode.Nodes(N_JSTAT).Text, 3))
item.SubItems.Add(titlenode.Nodes(N_PUBLISHED).Text)
[Code] .....
The listview is set to details view. What I want to do is group the book titles by series. For example, books by Michael Connelly may be grouped by "Harry Bosch", "Jack McEvoy", "Mickey Haller", etc. I can create a new group for each new series by
groupnum += 1
group = New ListViewGroup("group" & groupnum, _
System.Windows.Forms.HorizontalAlignment.Left)
group.Name = "group" & groupnum
group.Header = series
But I cannot find how to add the group to the listview and add the new item to the associated group.
