Ok, I have a usercontrol in a Class Library Projects which contains a Button, 2 Listboxes, and a Progress bar. My code is to look for a file and if its there post to one listbox and fill in the progress bar and also put the programs current task in the other listbox. Recently, I started using VB.Net 2010 Express and wanted to turn part of a form into a .dll so it would be easier to update. I started getting a error and had to declare a variable as a New instance of UserControL1 (my user control). When I did this, the control would run, but the Progress Bar doesn't fill and neither of my listboxes show anything. What Should I do?
I have a Visual Basic Class Library project. It generates a DLL. Is there a method to generate a static .LIB to which I can do a static link?Alternatively, can I do a static link against a DLL?
I am trying to track the progress of a file that is being extract with a progress bar. but i have no idea on what i should set as the max of the progress bar and the value..
here is my
Private Sub Button2_Click(sender As System.Object, e As System.EventArgs) Handles Button2.Click Dim ZipToUnpack As String = "C: est.zip"
Private Function GetMD5(ByVal file As String) As String Dim md5 As MD5CryptoServiceProvider = New MD5CryptoServiceProvider Dim f As FileStream = New FileStream(file, FileMode.Open, FileAccess.Read, FileShare.Read, 8192) md5.ComputeHash(f)
[code]....
It works fine, but when working with very large files on the network my users sometimes panic.I'd like to add a progress bar that updates based on the progress of the hashing through the file.So, my choice are either to manually create the hashing process, which I believe will be much slower,or somehow tap in to the position value of the filestream and use that to update a progress bar.I'd be happy to tap into the events of the MD5CryptoServiceProvider if I could, but I don't see anything there.I have searched the net to try to find an example and have only found code that works by reading line by line from the filestream, not from it being passed to another control/service.
My module won't run, it can't find the project or library, and highlights: the Date function in: MsgBox (Date).This is happening to several VBA functions, but this is the first one.I have all the libraries referenced that I think I need, especially the Visual Basic for Applications checked.There is a MISSING: Office12 library, but the Date function is part of the VBA library, so I don't think this should be the issue.

I have a class library in VB.NET that does a NET-envelope for an USB device driver.There is only one function of that driver that I could not envelope in a traditional class, but I had to put it in a Windows Service as described here:Sharing a class property (field) between applications.The Windows Service works fine, but I have now two projects for my NET-envelope: the one with the class library, the second with the windows service and I do not like the idea to maintain two distinct projects for the same driver.Is it a good practice (or even if possible) to add a windows service class to a normal class library (without creating its own project as described in the vb tutorial)?I know, in any case I should create a separate setup only for the windows service, but in this way I could have together all the classes that envelope my usb device driver in only one project.
i am using VB 2008. And i want to tell you that there are many basic features not yet available with controls. 1] Blank Date (Null Date) with DateTimePicker Control (user may not want to write date for some fields) 2] NumericBox for Writting just Numbers having properties AllowDecimal, AllowThousandSeperator, Min. n Max.Ranges. 3] Multi Column List for ComboBox. 4] 'Contains' type Lookup (finding) in ComboBox and AutoComplite enabled TextBox which finds for the strings in any part of String. Why developers needs to rely on third party control vendors for these Basic Features?
I am using the DownloadDataAysnc. But the ProgressChanged event doesn't show progress until after the data has been downloaded.Even when I try and download a data which is contained in a big file. The programs remains responsive so I know it is doing something.However, it is when the progress has completed that the progressChanged event fires.I known this as the progressChanged and the DownloadDataCompleted fire immediately after each other. However, they should be a pause as the file is quite big.This is the code snippet I am currently using. And the output below
so im running a program, that when a button is clicked, it will increment a progress bar, and loops a code i have, until the progress bar is done. The problem is i want the bar to go slower, i have it incrementing like
I've createda vb.net class library where I've defined a number of small classes... nothing complicated, just working with strings, sending emails, etc.In another project, I reference the class library and I'm seemingly able to create an instance ofone of tclasses - intellisense shows me all of the plic properties, methods, etc... all looks perfect. No compile errors at all, nothing b gumdropsand lollipops.When I run the app I'm working on that references the class library, it fails at the point where I'm creating an instance of the class and gives me a vague exception, "System.TypeLoadException".
I was looking for a solution to run a lengthy job (looking for files on the fixed drives) withouth freezing the UI, and saw that using a BackGroundWorker control is the recommended solution.
Problem is, I don't see its ProgressChange event being triggered:
I'm trying to download a file, which works fine, but the progress-bar is showing me no progress and because of that the form doesn't close. Could anyone tell me what is/could be wrong with my code. The weird thing is that the same code is working in my another app. [Code]
I wrote an application that connect to a SQL Server Db and fill some tables in dataset and calculate some functions based on record's items. But I can't run this application on other pc correctly. some tables fills in dataset and I can retrieve the data, but some tables not fill.
I think the problem arose because of Windows 7, but when I was at school the program worked. The program fills in the text boxes with information from Microsoft Access. However, my laptop has Windows 7, and when debugged, the information doesn't fill in the text boxes like before. Also, for added information, the school's computers run with Windows XP.
I have made a class using New->Class Library. I have 2 constructors, 1 function (that computes length of circle), one subroutine that computes area of circle, and main subroutine.
Public Class Class1 Class Circle Dim rad As Double
[CODE]...
My problem is when I try to run the program: No errors of syntax.
What I must do? I need to right click in solution explorer add new item->add->class and copy here this code?
After I write the code I chose from the vb menu: Build->Build Solution_name
Before writing the code I choose File->New->and selected class library then save all to save as a project.
Or class library is only a dll file that runs with a windows forms application. (that is added after i write the code for write library).
I am currently developing a service using the SharePoint 2010 Client Object Model to programmatically upload Excel worksheets to a Drop Off Library and then set the properties on the file. This process is working well. However, the Drop Off Library is governed by Content Organizer Rules that aren't being applied to the uploaded file. I have examined every property I thought I could have missed: [code] What's most frustrating is that if I edit the document properties using the Web UI and check it back in without making any changes, the file is moved to its final location. What might I have overlooked that is preventing Content Organizer Rules from being applied to newly uploaded files when using SP2010 COM?
there's a lot of dlls i've got one in the Release folder and one in the Debug folder under bin, there seem to be one in the obj folder as well.they all seem to work fine, but which should be the correct one?
I have two projects; A and B, where B needs to use some classes that are in project A. Hence, I added B to A's solution, and in B I added a reference to project A.
Is that sensible? Or should I rather put those classes in a class library?
I see that if I further want to open form/program B from a menu option in project A, then A needs a reference to B. Which would not be possible if B already had a reference to A. However if I use the class library for the common classes, then it's ok as B doesn't need the A reference.
Does this sound logical? It would be nice to know what are typical reasons for putting projects in the same solution, and if it's advised to use libraries aggressively to refactor common code between two projects, even if it's just a couple of classes.. Yet I've never made my own library, so a bit unsure on when to use it.
I'm merging two of my projects that can share a lot of the same classes into one solution with two web applications and a shared class library.
I've literally just dumped all the classes into the class library project and as expected I've got a ton of errors to fix. My main problem at the moment is the connection string. Currently I have this (which is obviously not going to work):
''' <summary> ''' Initialise the data access layer by loading the database connection string from the Web.Config file
I'm in the midst of developing a class library DLL for a third party application. On my machine, the developers machine, things are going along smoothly. I can compile/build and my DLL is loaded, and thus works as expected.
I've been copying the contents of the Release directory from C:Solutions...Release to C:ProgramDirectory. I realize now that my DLL is loaded into memory from the Release folder, and not the folder I copied it to.The point being of course, I want to distribute this third-party add-in to my users. And sure enough when I try that, presumably the DLL isn't loaded into memory and thus not available to the user, like it is on my machine.
I tried the first obvious thing and registering the DLL on the user's machine, but that failed."The module "..." was loaded but the entry-point DLLRegisterServer was not found." It's apparent I am missing some key step or caveat when it comes to developing this class library.
I`ve made a .NET component in C#. After that, i`ve created a class library in VB.NET and added this C# component and a couple of buttons to the library (creating another component now with buttons). So far, so good.The problem is: when i use this final component (vb.net class library), i want to link all MouseClick Events of its own components (buttons and C# component). In other words, when i add this final class library to my VB solution, it has its own MouseClick event. But when i click inside it doesnt raise the click event unless i do not click in the buttons or in the C# component inside it. I want to raise this event in the application wherever i click (inside or outside its own components).
My objective is to take a .vb class file that is used on multiple local applications/web sites and convert it to a .dll file that would would be deployed to the servers that we use.The code all works, I can build my class library project with Visual Studios 2008 Pro and end up with a DLL.I can then drag and drop the DLL into any application or website and use it successfully What I'm missing is how to compile it correctly so it will do two things;
1. Get it to show up as a .NET component
2. Get it to NOT scream at me when I try to reference it.
I think part of my problem is that I've been looking up assemblies and dll's when maybe I should have been looking at component authoring.No, I don't want to just stick with the drag and drop into local bins. I might as well just copy and paste the original .vb at that point.
I was dangerously close to high-jacking another thread, so I thought I should create my own. We make class libraries so we won't duplicate code, but what about settings? I have a large solution that I've created a project in for common material, which includes an app.config. The problem is that a class library isn't an "app" so my functions can't get to the values. How do I get around this?
