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
I posted in the wrong forum the first time around, and I'm pretty sure that's why it never even appeared. Oh well. THIS is the right forum now, I hope, so here's my problem:
I'm basically simulating bowling. I've created a form that has a "scoreboard" on it, and I'm updating the cells of the scoreboard to display the bowl result. Without doing 21 if statements, I figured I could call a method, send it which roll number it is, and then use a for loop to update each label's text values.[code]...
Is it possible to create a routine in VB.NET with a name-based parameter array? The WebMethod attribute built into the framework is used exactly this way: WebMethod(BufferResponse:=False)
Specifically, I'd like to use it in a class' constructor. I'd like something similar to this:
New MyObject(id:=10,buffer:=True)
I'm not even sure what the terminology is for this kind of parameter list, so I can't even find it when searching.
I 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?
I'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)
[code]....
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"
This 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.
MsgBox(CurPat, MsgBoxStyle.Critical) If (CurPat = "True") Then Dim lblTemp As New Label
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 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.

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.
I'm just writing a quick program that will ping servers on my network and display the results back to me by changing the color of the Server (item) in a listview control.
I have an application that downloads about 19,000 records from a SQL table and I need to step through all the records doing a calculation on each then create a new Excel workbook with the data. [Code] m_rows does accurately report that the number of records in the datatable is the same as in the SQL table. I can add records to the XLS file with a for/next loop but they are all the first record of the datatable. So now that I have the data, how do I go through each record sequentially?
I want to rearrange a list of items in different orders for few times; ie: the 2nd in the list becomes the 1st & the previous 3rd becomes the 2nd, ... then the Last one becomes the penultimate one.In the next round, the 3rd of the original list becomes the 1st & the 4th of the original becomes the 2nd and so on. (That is, each item moves one rank above & the Top one goes to the Bottom)Given below is an example.Here, I took only 6 items & rearranged for 5 times only. (I should be able to use several Items and to rearrange for many times).The Original List:
Learning about threads at the moment, barely managing to wrap my head around it, anyway I was wondering how you would go about making threads run sequentially from threadpool if you added them with threadpool.queueuserworkitem()
In my code currently I know it is not running sequentially as I set it up to call a function and print a number each call. I gather this could be achieved with using synch lock but not quite sure how.
Is there any way using existing .NET framework classes/methods that you can sequentially read a byte array? I dont mean just using a for loop to loop through from the beginning to the end, I mean having the kind of methods that you have when working with an IO.Stream subclass, such as ReadByte. I thought I would just be able to construct a new IO.Stream class and pass it in a byte array but it seems that Stream is just for inheriting and cannot actually be used itself. I could implement my own class that just has an internal position counter and a byte array and then each time you call ReadByte on that it advances the position and returns the byte at that index... but it seems odd to have to implement such a basic thing myself.
I created a program that has serval labels on a form and a listview object. It has a button that when clicked reads a textfile and loads up values in the listview object. I then can click and drag text from the listview box to any label on the form and then the program removes the value from the listview box. Now, my question is how can I instruct VB to save these values in the text property of the labels so that the next time the program is loaded the labels will contain the values loaded during the last run time session?
Well im currently developing an application for public use, I have a login screen in which the user enter's their registered credential's and the progressbar loads by increments of 3, now i placed 6 labels ontop of eachother and where the progressbar coding is i put:
If Progressbar.Value >= 1 Then Label3.Show() If Progressbar.Value >= 20 Then Label3.Hide() Label4.show()
And so on up until Label8 Show at 100%,
Now the problem is... As i have placed the labels ontop of eachother i need them hidden until they are called to show, i have tried adding a background worker to do this but have had no luck, all i see is the labels overlapping eachother when i run my application when i want them hidden untill Label3.Show() is called, and then to display them as they are called and hide them when another one is called to show...
With VB, but I've got the few basics down, file naming, adding objects, naming objetcs, etc. But the reason I'm on here is because I cannot complete even the first step. Our form is 640 X 480, and we need to have two labels, both have vertical scrolls. I know how to add and resize the labels to meet my needs, but I do not know how to create scrolling labels. Or are they text boxes? On our bubble chart (Do you know what that means?) it says lblInformation. We are going to have clickable radio buttons which will update the lblInformation with info about each of the radio buttons.
I'm trying to make a program that allows the user to click on labels which have a number in it and then that value has to be stored into a different label.
For example the user click on label1 and the values goes into label12, then it click on label3 and the values goes to label13 and so on.
At the moment I can only code on the respective label underneath (1->12,2->13...) but it has to be in any order (5->12,7->13...)
Here a picture and below my code:
'defining the click order.... Private Sub Label1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Label1.Click
I am using Visual Basic 2010 and added a single image through the designer. The name of the image is "add.png". When I reload my form it gives me an error:
Warning 4 The type 'MyProject.My.Resources.Resources' has no property named 'add'. F:Vb2010MyProjectMyProjectFormsFrm.Designer.vb 599 0 Me.btnNew.Image = Global.MyProject.My.Resources.Resources.add
I Change this code to This : Me.btnNew.Image = Global.MyProject.My.Resources.add But its not work properly
Now that C# supports named parameters, I was checking to see if it was implemented the same way VB did it, and found that there is a slight difference. Take for example a library function like this:
public static void Foo(string a, string b) { Console.WriteLine(string.Format("a: {0}, b: {1}", a, b)); }
[code].....
The way VB does it requires much fewer instruction calls, so is there any advantage to the way C# implements it? If you don't use the named parameters, C# produces the same thing as VB.
EDIT: Now that we've determined that the extra instructions go away in release mode, is there a particular reason for them to be present in debug mode? VB acts the same in both modes, and C# doesn't insert the extra instructions when calling the method normally without named parameters (including when you use optional parameters).
I'm working on converting an Excel VBA project to a VB.net Office Solution. In VBA accessing a named range within a sheet was pretty easy.Sheet1.Range("NamedRange")would give you the value in that cell.
In VB.net I've tried several different things, all ending in failure. [url]...
I'm using one of the Visual Studio Excel 2010 Document template, and I managed to set a value in a named range on a sheet. The template creates a class for each tab on the worksheet, so I was able to do this.[code]...
I am very new to VB.net and for a project I am supposed to do some "outside research" and create a database. The database should consist of items (sports players) who have a number of different values (one set is physical: strength, speed, agility, acceleration) and preferably another (technical ability: ball skill, dribbling, shooting, etc). I want the database to classify these and give each traits such as "Power Shooter" if the shooting stat is upwards of 90, etc. I want to be able to bring up characters through this and also through named searches.
Ok, I've read every question on here about strong named assemblies and just want to clarify something. First though, from what I've read, GAC aside, strong named assemblies prevent a malicious 3rd party changing and impersonating your code. It'd be great to have some links to some real world examples of this kind of spoofing that happened pre strong named assemblies. If security or the GAC are not a concern, It seems that it's still advisable to strong name assemblies because:
(A) Clients who have strong named assemblies can only reference your assemblies if they are signed.
(B) Clients who do not have strong named assemblies can reference your assembly whether it's signed or not.
I need to create a collection that should have named indexes. e.g.: IN typical collection such as ArrayList :
Dim al as ArrayList = New ArrayList() al.Add("10") al.Add("20")
to access first element i have to use "0" in al(0)...such I need to create a collection that has Named indexes instead of Numerical zero based indexes. such as: assume the collectio object is col1. to access the value element "RegoNo", i should use the collection object as col1("RegoNo") or similar technique Is this possible to do?
