I am making a hangman clone for boredom and I can't seem to make the labels show up properly. Maybe I'm doing this wrong entirely and should just limit what's visible instead.

Note: I tried this with a textbox and it worked. The Textbox text was the labels closing, but when I used this with label, it didnt work.
I have the fonts needed to create barcodes and all the code written to generate them inclusive of the check digit. I have a SQL table that contains UPC codes for each item. I have searched high and low for an example in creating barcode labels and printing them however, I'm unable to find anything that does not require SDK to be purchased or mail merge in WORD etc. I need to be able to do this in VB .net for Windows. My label will have a picture of the product in the upper left hand corner of each label.
View 1 RepliesI need to create some serial port controlls manually. My program reads through a config file, and it if comes across an entry called COMPORT then I need to create a contol to talk to this port. The entries in the ini file might be
COMPORT=COM1
COMPORT=COM3
COMPORT=COM7
So here is my problem! I'd like to create the variable control name with part of the com port number, so I can always refer back to it.
EG.
Dim strVar as sring = "COM1"
Dim CName+strVar As New System.IO.Ports.SerialPort
With Button click i have to create dynamic 3 Labels in a Panel or panel. First Label show text from TextBox1. Second Label show text from TextBox2 And the last show date from DatetimePicker.
First problem: I have find some code to create one label but not 3 labels with different text each one. How to create this 3 different labels with different text? Each one under the previous. Second problem: When i create a label and close the form - Next time when i open again the form none label has saved. The Panel is clear. How to save that dynamic created labels?
I am deveolping a charting program and have a need to have dynamic draggable labels on the chart for notation purposes. Everything works fine until I try to drag a label past the 32767 (16 bit limit).
Here is the code that I drag the label with:
If ISDRAGGING = True Then 'DRAGGING LABEL
If CURRENTLABEL.Tag = 2 Then
CURRENTLABEL.Left = 0

I have tried to create a new label and override the Top value with a Long Value, but it still does not do the trick. Hhere is my attempt to overload the top value to an integer.
Public Overloads Property Top() As Long
Get
Return _Top
End Get
Set(ByVal value As Long)
[Code] .....
The charts are dynamically generated from a database and represent depths. Usually at least 10000 feet are plotted at 5 pixels per foot. So some labels will be created or dragged below this 32767 line regularly. Any way to be able to drag the labels past this limit, or possible another option to be able to view these long charts.
I'm currently working on a program where I'm trying to dynamically create a picture box, a button, and a label for each item in a text file. Any ideas on how to do this? What I have: a plain text file with a list of numbers. Each number corresponds to a location. When that file is read, I want to create a picture box, a button, and a label related to each number. If I want to add something to the screen, all I Have to do is add a number to the file. So, lets say the file has. 1, 2
When the file loads, it will create a unique item on the display for each location. say pic1, button1, and label1 and pic2, button2, and label2. Right now, if I add something to the file, I have to go back into the editor and manually add everything. Which is a pain.
I search for a grand total of about four hours online for a method of how to get transparency working in labels in VB.NET 2008. After finding nothing but some example that I have no idea how to implement into my project, I have almost given up. Yes, I've heard about setting the parent properties, but in my case it is imperative that I have labels on top of a PictureBox. (Apparently it's not possible through normal means to have transparent labels over PictureBoxes.)I'm losing my patience with VB.NET, even considering switching back to VB6. How could Microsoft make such a stupid decision? Today I decided to use a stupendous workaround and instead of labels, use transparent PNGs of bitmap text. And guess what? It has the exact same problem as the labels when placed in front of controls! The transparent background has been set to the colour of the form's background!
View 5 RepliesI need to create an Array of Labels. I am using A With Code block to set the properties of the Labels as well as the Data Binding. I want to set the LabelIndex inside this block as well. How do I go aboute this?
View 8 RepliesI'm trying to make labels at runtime. The idea is to create them on the fly in runtime.
I have this on my form:
btnAdd
txtName
txtAge
[Code]....
Which work fine, but if I want to create another label, how do I check to see if one or more labels have already been created and then apply a new location of the new label? (so it doesn't get override on the same location on the form?)
i am attempting to create and then update data in Labels using VB2005.I create the label when the form is loaded using this for loop
For j As Integer = 1 To count
Dim name As String
Dim m As String
ReDim L(count)
[code]....
This creates the labels and text boxes in the form. Later in the program I would like to change the text within both the T1310() and T1550() text boxes and I am attempting to do so with the following code.
For j = 1 To count
status = OP930_SelectModule(j - 1)
status = OP930_SetWavelength(1310)

I get errors on the Blue lines. Everything compiles fine, but when the software goes through the loop I get the error "NullReferenceException was unhandled"
I am using a variation of Stanav's example from the previous post seen in Sub dd_Inhoud_Labels. The first 3 Subs (Add_Titel_Label, Add_Byskrif_Label & Add_Lewering_Label) is allso shown below so you can see what I am leading up to. Sub Add_Inhoud_Labels is not only responsible for creating labels but allso placing them acording to the location and size of the previos label and allso ather properties as Font and so on depending on the marker at the start of the text string saved in the data base.The problem I can not get solved is that only the last of the Inhoud Labels seem to be created, it seem to be in the correct location as last label as seen in the pic below
View 3 RepliesThis may be simple, but im having a tough go at it. I'm trying to make a "review" section in a step through form, where the user can see everything that has been entered and if they choose go back and "edit" that information again. One section only has to show the information that has been added by the user, basically if they don't select a certain checkbox there is no reason to display the info for that box.I want to to dynamically create labels in a Panel (Panel7) on a TabPage (TabPage3), only for the checkbox information that was selected. This is what I have right now, and I am unable to see anything on the page, I have also tried without the panel and straight onto the tabpage itself to no avail.

I have a simple poker game that deals out 9 cards into pictureboxes and shows another 3 pictureboxes that hold cards for the dealer. The code itself does what I want it to...even though I'm at a dead end with writing the code further to evaluate the poker hands. I would simply like to add a few labels and a combobox to my form, but everytime I add something, or try to add it I get cast error?

I'm currently making an application that involves time tables / scheduling. I'm required to generate a timetable for school teaching activities. in this application, I want to display the time slots using labels and I want to enable users to drag them around to place the subject cards in the available slots. I'm even confused with the control to use for the time slots. Right now I'm thinking of using datagridview for the time slot. So I'm trying to drag the labels around and placing them in the datagridview cells.

I have a windows application that dynamically loads DLLs using Reflection.Assembly.LoadFrom(dll_file_name_here).
It works as expected, until I ILMerge the application with another DLL.
So this scenario works fine:
MyApp.exe
MyAppComponent.dll
Plugin.dll
Once I ILMerge MyApp.exe and MyAppComponent.dll resulting in:
MyApp.exe
Plugin.dll
Calling Reflection.Assembly.LoadFrom("Plugin.dll") seems to load successfully, however once I try to do anything with it eg:
foreach ( typeAsm in Reflection.Assembly.LoadFrom("Plugin.dll"))
I get an exception "unable to load one or more of the requested types. retrieve the loader exceptions property for more informtion".
The frustrating thing is I can't really debug it, because debugging pre merging works perfectly!
I am trying to create a dynamic dropdown after a dropdown has been selested (in asp.net vb)
For example: I have a dropdown question that asks: What brand of car do you drive (Toyota, Ford, Honda, Nissan, Chevrolet)
When the brand is selected I want another dropdown to appear under it with new chocies
For example: If Nissan is chosen, the second dropdown will be populated (from the database) with (Altima, Maxima, etc...)
And in some cases I would like a text box to appear, but If I can figure out the dropdown portion, I am sure I can figure out the textbox.
