Are DLL files created by creating a Class file in VB ? If not, what are their purpose ? If I were to create a class that held the functions I needed for my program to function, would the class file compile with the assembly as a DLL ? Do I have it all wrong ?
can someone please help me with a textbox? I have created a new class and require this textbox field within a sub in the new class but i get Error1 'TextBox1' is not declared. It may be inaccessible due to its protection level.I have tried MyClass.TextBox1 = Form1.TextBox1 but I get declaration expected.
I wrote a quick and dirty web service in VB.NET. And as it always goes, I want to move it to production, but don't want to use the name Service1 for the public class. When I change the name I get an error when trying to reference it. I know there is somewhere else I need to change the class name, something in the code behind but I can't find where it is.
I have an app (vb.net) that sues multi threading and have tow problems.
1. The program is used for trading currency markets and mointers prices all day. When a signal is generated it wil place a trade in a new thread. In the new thread it checks to see if a trade is on already and if so it will not place another trade.The problem is it can be too fast and place another trade before the server has processed the first trade. So trade count returns 0. As the system watches 6 accounts I can not just pause the other thread to make sure it has finished before trying ot place another trade.How to i check to make sure the first thread is finished so when i check for trade count it retuns 1?
2.The new thread is inside a class and has a logging class as well. The problem is writing to the text box on the main thread. As the logging thread is created in the new thread it has no access to the textbox. I have tried using invoke but it still does not write to text box as it does not exist in the new thread.How do i reference a form from a class that was created in a new thread?
I've created a custom class that I've grown rather dependent on in my coding. I've encapsulated it as it's own "Solution" and use a reference to the class module within the solution on most of my new projects, and that all works fine. It seems slightly clunky to me that my encapsulated class module is packaged with solution-related directories and so forth. For me, this seems to make management and maintenance of these little class modules difficult (renaming them for instance). So now, a few questions:
When you recognize you have a useful class embedded within a solution: 1) What's your method for encapsulation? (is there a template you like?) 2) How do you organize/arrange your code libraries? 3) When, if ever, might you consider using that "Code Snippets Manager" thing in the IDE?
I'm struggling a bit trying to understanding how Visual Studio wraps-up everything in what appears to be a "Solution" umbrella. There doesn't seem to be a lot of write-ups on how to go about organizing your code libraries to work well within this Solution/Project Visual Studio framework.
I have created a class which generates a form in code. I have hooked up the buttons and a text box so that they work. Now, I am trying to hook up the Resize event (and probably will need other events) for this form. How do I do that? If I can understand how to do it for the Resize event, I should be able to apply that to whatever other events I might want to use. I can't just put "Handles frmMyForm.Resize" or "Handles Me.Resize". I get the message "Handles clause requires a WithEvents variable defined in the containing type or one of its base types." This all has been a learning experience.
I didn't think this would be a problem, but it appears that others also search for this solution. There is an annoying DING! when hitting the Enter key in a ComboBox in VB.Net so I sought solutions. Here is the solution I am working with. I created a new seperate Class within my Project...
Public Class ClasscboBox Inherits ComboBox
[CODE]...
Looks good, but I am having a problem calling it from the main project. Here is what I have tried using...
Dim objcboBox As New ClasscboBox objcboBox.OnKeyPress(KeyPressEventArgs)
However, it says thatKeyPressEventArgs is a Type and cannot be used as an Expression. I tried 'e' but no go. I am a little ahead of my classes (no pun intended) so I am likely missing something about what I am doing wrong.
I have three comboboxes so I though this would best suit my needs in the interests of writting decent code and not populating each call with repeating code.
I have created an application where from the starting class a modless dialog box is called. Once the dialog box is called then the program will close instead of waiting on the dialog box to call the appropriate functions.
A couple of notes: This was originally written in VB 2005, and I was successful by manipulating the automatically generated code for the starting and clean up for the class. I cannot find this section of code in my VB 2008 project.
I cannot start the program from inside the dialog box, since there are multiple dialog boxes and which one starts depends on what is currently running on the computer.
The program will run with a modal dialog box, but it does not function properly, so I must use modless.
Please help me to prevent the application from closing when it reaches the end of the code in the main subroutine. I want to have a function to explicitly close the application.
I am in the beginning stages of learning VB.NET and all I want to know is how you link a created Class Library to a Form? I've seen code at the top of the designer window that says <dim objSomething as New somethingClass> What the heck is that and how does it work?
Something like in the image.I know that <Description("blah blah blah")>_ gives the description, but when the user is in the designer tab, I would like to know how to add that info when intellisense pops up.
It is in the file ClientProfile I have placed in both App_Code and also App_Code/Models
In my code behind I have the following
[CODE]...
The last word, "ClientProfile" has the scary squiggly red line below it. It is not recognizing my class.Even the Intellisense is not picking up te class. Do I have to register the class file in any way?
Under Visual Basic 2010, I am trying to define a specific instance of a static method that was created as a Java class. I have a vendor supplied dll added in as a reference.[code]...
But, I can't seem to define a specific instance of this method. Using "IntegrationMethod.getIntegrationMode()"always returns a value of zero.
There doesn't appear to be any way to "setIntegrationMode" to a specific value.
The documentatoin for this Class as provided by the vendor are shown below.
When I asked the vendor for assistance, their response was: "
Our javadocs for the IntegrationMethod class show that we provide three predefined instances of the IntegrationMethod class[code]...
I'm going through All-In-One Code Framework Coding Standards document and one of the recommendations is to add a file header comment at the start of every human-created code file. This is the first time I've seen such a recommendation and to me it's just an unnecessary and ugly clutter but I'm wondering if someone could explain why M$ recommends this?
Imports System.Threading Public Class TestClass Private myClassThread As New Thread(AddressOf StartMyClassThread)
[code]....
The result:Application runs, no errors or exceptions.Displayed is the listbox and the Start button.I press the start button and a msgbox says "Not Invoked" as expected and upon clicking OK to that msgbox "Start Button Pressed" is added to the Output listbox control.Immediately following that the msgbox pops up again and says "Not Invoked". I was expecting "Invoked" as a separate thread is trying to use the Output listbox control.Of course this results in the Output.Items.Add being attempted which results in no visible result as the thread is not allowed to directly update the UI control.
so I used to mess around with C#, just a little. And someone had helped me make a class for Visual C# that was supposed to do the math parts for "internal structure" - which the program used for a part of its calculations and screen... Basically there were 2 options. Endo-Steel and Standard. The user would use a updownbox to determine weight of the machine and then internal structure was a % of that total. If it was standard then it was 10% of the overall weight, if it was Endo-Steel then it was 50% of standard (so 5% of total weight) rounded to next 0.5 (so .25 was .5, 1.25 was 1.5, 1.75 was 2.0, etc). I have the code for the C# class file for it, but want to make it in VB.
I'm having a problem with a class issue in VB 2005. The error message reads "The class Tellerform can be designed, but is not the first class in the file. Visual Studio requires that you use the first class in the file. Move the class code so that it is the first class in the file and try reloading the designer again."
I have an editor created invb.net that creates html files. And when i click the button run , the Internet Explorer opens my file that is inside the Richtextbox.
i am creating a console app that will delete pictures from a directory every 30 minutes. Problem is that its being populated by files every minute or so. So if i go and delete files in that directory then it may cause an error trying to delete a file thats being created just then or opened.
I currently have this code to copy the files to another directory and then delete them from the source directory.Dim f() As String = Directory.GetFiles(sourceDir)
I am trying to add text to an already created file on vb.net. When I run the program there are no errors and it writes everything to my liking, but currently when it goes to save, it makes me create an entirely new text file with any name I choose to give it. What I need to do is for it to automatically get added onto the end of an already created text file without deleting any other part of the file, which we will call "data.txt." Here is the code I already have
Imports System.IO Public Class Frmadd Const FILE_NAME As String = "data.txt"
I have an aspx page in VB that fills a pdf with data from a web form.I'm using iTextSharp for this and I have no problem with this.This is the second time I've created anything for pdf's and I'm using the code from the first script.The first script wrote the filled in pdf to a directory on the server where one person could access those via another aspx page. I wrote that code probably a year ago.Now, instead of having the filled in pdf sit on the sever, I have to email it, which I was successful at doing.The only issue left is to delete the filled in pdf from the directory.I tried to use file.delete(), but I got an error stating the the file was being used by another process.how to stop the process in order to be able to delete the file.[code]
I want to move a file, when it is created. I have filewatcher and I know filemove function, but I don't know how I can create condition, that the file will be moved, when it is create. [Code]
I have a small project that simply copies some downloaded files from one directory to another. It is actually updating another program. The program is in the Program Files directory, therefore I need to elevate in Vista to requireAdministrator. I went to properties, clicked the UAC button, made my changes, compiled, and...no manifest file is created.
