I'm making an art program involving 8x8 squares on a grid, but there are 64x64 grid square PictureBoxes for each grid square. Meaning there are 4096 picturebox squares to be setup.
I'm having them names like pic0001, pic0002, pic0003, etc... but re-naming them individually would take me forever.
Is there a way to mass re-name them at once?

I'm creating a car class. Make and model are properties but both make and model appear to be reserved words in C#. What's the best practice for naming properties/methods when your preferred name is a reserved word?My first instinct is to call the properties CarMake, CarModel (so a convention of ClassNamePropertyName).My mistake, make and model aren't actually reserved words. VS intelliesense and code coloring made it appear so to me at first glance. Though my question does stand for future reference.

I want to rename a folder of jpgs with their datetime original from the exif meta file. The line: My.Computer.FileSystem.RenameFile(foundImage, NewPictureName) does have the all the right info: the original file folder and name; and the new picture name - it just doesn't actually do the task.

View 2 RepliesI have a program that will rename files that the user selects. The problem is even though when you go through the whole process, and it works successfully, it doesn't rename every file.To all people new to vb, try not to code like this as it is about the worst way to use a loop. I was in a hurry last night so i took the easy way out [code]Again, bad coding practices throughout the whole project, but the program will probably only be used by my dad so it will do.Note that the form: "Name and Ext" will not be shown when the program is all finished.

I have to rename a bunch of folders in different directories. What I would like to do is type in a directory and rename/move files into another directory. I have 4 txt files right know, one for the old file names, one for the new file names, and 2 for the directories.
I planed on importing the txt files into 4 arrays and then using the rename function to change the directory going through a loop.
Problem is I'm very very new to VB and have no idea how to import each line of the txt file into the array.
I would like loop through control names at run time. Is it possible to do something like the following:

Let's say I have the following class structure (simplified from my real-world problem):
Public Class PC_People_Container
Private _people_list As New List(Of PL_Person)
Public Sub New()[code].....
If I were to serialize this, I'd get the default assigned node names in my XML. That means my root is named PC_People_Container and each person in the list is marked up as PL_Person. I know I can change the root node using <XmlRoot(ElementName :="PeopleContainer")>. The trouble is doing that for the subclasses. I can't use the <XmlRoot> tag on PL_Person class because there can't be two root elements, and IntelliSense throws a fit when I try to use the <XmlElement> tag on a class like I would on a property. Is it even possible to control what those subclasses are named when they're serialized as child nodes?
How do i edit the column header of the GridView control on a web form? I have added a Table to DataSource as:

How do you use a parameterized query to make the (last_name, first_Name) appear in the same combo box? I know how do drag them over from the DATA SOURCES menu, but I am trying to combine them.

VB.Net's DataGridView supports naming columns, but I was wondering if it could somehow do the same for rows, so that we could use something like this:
With DataGridView1
.Rows.Add(4)
.Rows(0).Name = "Setting1"

Do you confirm that it's not possible and we must use numeric indexes to refer to row numbers?
I am coding an invoicing application. The user should be able to add a new line to the billing section of the invoice by selecting a product from a ComboBox, which subsequently fills out various other fields (price, description, etc) based on the selected product.
My problem is this: When the user adds a product, I would like the program to automatically generate a new line for the next product. It seems like the only way to accomplish this would be to create a new set of controls with an incremented name, i.e. Product1, Price1, Desc1 for the first product, Product2, Price2, Desc2 for the second product, etc. Is this possible, or am I going about it all wrong?
I am using Visual Basic 2008 Pro. I am trying to figure out how to bind a set of column headings in a DataSet (or DataGridView) to a ListBox. I want to show the column headers in the listbox control (not the data), and allow users to select one or more items
View 4 RepliesI don't usually use VB but now I must for an assignment. I would like to know if it's possible to change the display name for an object on a listbox. For instance, if I add to it a user defined class, there's a way to provide it's display name, instead of converting it to string and then add it.
This is what I have
Dim format As String = FormatOutput(object)
Lista.Items.Add(format)
I would like to have the same output, but instead add the object.
Note: if such is not possible, then how can I associate the list box selection to the actual object? Doing it by index is painfull, because I'm using linked lists (ie., instead of arrays).
Note 2: python has a __str__ method which is called by default when the object is cast to string. Is there anything like it in VB?
I need to iterate through controls using dynamic construction of control names and it looks like this could be what I need, however I never used this before and it does not quite work. What am I doing wrong? GroupBox1 is what I am attempting

View 3 RepliesI've created a Custom Control, and I will be placing a large number of instances of that Custom Control on my xaml page. In working with that Custom Control in the VB Code Behind, how do I do the following?
How do I reference the name of the Custom Control (in my VB code) which was clicked with the MouseLeftButtonDown event? For example, if I have 10 instances of my Custom Control in xaml, each with a different x:name (say 1-10), when a particular instance is clicked, how can I see which one was clicked? I've tried a number of things including e.OriginalSource.Name (which returns the component within the control which was clicked and not the name of the instance of the control). My Custom Control consists of numerous parts and pieces (Rectangles, Lines, Text, etc). Each of these items is a part of my layer. In VB code, once I can reference a particular Control, how can I hide or change certain parts of that control (such as hiding a Line, and changing the text). Also, I need to modify more than just the control which was clicked, so I need to be able to access properties of all of the controls, not just what was clicked. For example, if I click Control instance Test1, I also need to modify Test2, Test3, and Test5 in some way.
Here is some test code I through together as part of a Silverlight project using MS Blend 2. My control is much larger, and I need 200 - 250 instances/copies of that custom control, so I really need to know which control instance/copy was clicked.

View 4 RepliesI am using a Microsoft Chart control (system.windows.forms.datavisualization.charting.chart) in a Windows forms application, vb.net 2008.

I tried adding a slash, making it c:\newfolder, but this only changes it to c:[newline]ewfolder. Is there a workaround for this behavior?

Chart1.Series(0).ChartType = DataVisualization.Charting.SeriesChartType.Pie

In the windows form designer, I added a StatusStrip control, made some changes to adding items and changed the names of the items to names I would recognize, for instance I changed "ToolStripStatusLabel3" to "lblMode". All was fine until I inadvertenly deleted the StatusStrip. Now when I add it back to the form and try to change the name I get an error saying that the name "lblMode" is already in use. And sure enough it is listed in the items of the properties window, but not dislayed anywhere.
I am not sure how to resolve this. I know there is a window, I think its called "Project Designer" or something similar that is code where controls get added but I CANNOT find this window to view the code.
