• Clean way to display/hide a bunch of buttons based on a ComboBox selection

  - by John at CashCommons

  I'm writing a standalone application in VB.NET using Visual Studio 2005. I want to display/hide a bunch of Buttons based on the selected value of a ComboBox. Each selection would have a different set of Buttons to display, and I'd like to have them arranged in a nice grid. Driving a TabControl with the ComboBox value would be the kind of behavior I want, but I don't want it to look like a TabControl to the user because it might be confusing. Is there a way to do this? Basically, I'd like Selection1 of the ComboBox to show Buttons 1-4, Selection2 to show Buttons 5-11, Selection3 to show (maybe) Buttons 1, 3, 5, 6, and 8, etc., have them arranged nicely, and have the GUI show only the ComboBox and the buttons. Thanks in advance as always!

• Web Service appears as website instead of developer web server

  - by stocherilac

  I recently reimaged my PC and regrabbed one of our projects from Source Safe. In our solution we have a web service that normally runs on a server, however we can build the webservice on our localhost for debugging as well. However, now whenever I grab the project from source safe it is building the webservice as a website instead of a developer web server. This is causing a variety of issue, specifically I am no longer able to specify which port I would like that webservice to use. As a result I cannot connect to our database through my local webservice. How can I change the project in my solution that controls the webservice from a website to a developer web server? MS Visual Studio 2005. MS Visual Source Safe 2005. MS SQL Server 2000. VB .NET project

• DataGridView and checkboxes re-selecting automatically

  - by SuperFurryToad

  I have a strange problem with a DataGridView I'm using which is bound to a table in VB.net I've added a checkbox column to allow a user to tick a bunch of rows that I can then loop through and save off to a different table. All the checkboxes are enabled by default. So it's really a case of unchecking the rows which aren't required. However, the DataGridView re-enables any checkbox that I click after I click on a checkbox in another row. So in effect, only one row can be unchecked at a time. I'm sure I'm probably missing something obvious here?

• Any homologue of InternalsVisibleToAttribute, but for internal classes?

  - by Will Marcouiller

  In my most recent question: Unit Testing Best Practice? / C# InternalsVisibleTo() attribute for VBNET 2.0 while testing?, I was asking about InternalsVisibleToAttribute. I have read the documentation on how to use it, and everything is fine and understood. However, I can't instantiate my class Groupe from my Testing project. I want to be able to instantiate my internal class in my wrapper assembly, from my testing assembly. Any help is appreciated! EDIT Here's the compile-time error I get when I do try to instantiate my type: Erreur 2 'Carra.Exemples.Blocs.ActiveDirectory.Groupe' n'est pas accessible dans ce contexte, car il est 'Private'. C:\Open\Projects\Exemples\Src\Carra.Exemples.Blocs.ActiveDirectory\Carra.Exemples.Blocs.ActiveDirectory.Tests\GroupeTests.vb 9 18 Carra.Exemples.Blocs.ActiveDirectory.Tests (This says that my type is not accessible in this context, because it is private.) But it's Friend (internal)!

• Get the BindingSource position based on DataTable row

  - by Ronald

  I have a datatable that contains the rows of a database table. This table has a primary key formed by 2 columns. The components are assigned this way: datatable - bindingsource - datagridview. What I want is to search a specific row (based on the primary key) to select it on the grid. I cant use the bindingsource.Find method because you only can use one column. I have access to the datatable, so I do manually search on the datatable, but how can I get bindingsource row position based on the datatable row? Or there is another way to solve this? Im using Visual Studio 2005, VB.NET.

• Newbie Question: Read and Process a List of Text Files

  - by johnv

  I'm completely new to .NET and am trying as a first step to write a text processing program. The task is simple: I have a list of 10,000 text files stored in one folder, and I'm trying to read each one, store it as a string variable, then run it through a series of functions, then save the final output to another folder. So far I can only manage to manually input the file path like this (in VB.NET): Dim tRead As System.IO.StreamReader Public Function ReadFile() As String Dim EntireFile As String tRead = File.OpenText("c:\textexample\00001.txt") EntireFile = tRead.ReadToEnd Return EntireFile End Function Public Function Step1() ..... End Function Public Function Step2() ..... End Function .............. I'm wondering, therefore, if there's a way to automate this process. Perhaps for example store all input file path into a text file then read each entry at a time, then save the final output into the save path, again listed in a text file. Any help is greatly appreciated. ReplyQuote

• Modify HTML in a Internet Explorer window using external.menuArguments

  - by Axeman

  Hi all... I've a vb.net class that is invoked with a context menu extension in Internet Explorer. The code has access to the object model of the page, and reading data is not a problem. This is the code of a test funcion... it changes the status bar text (OK), prints the page html (OK), changes the html by adding a text and prints again the page html (ok, in the second popup my added text is in the html) But the Internet Explorer window doesnt't show it. Where am I doing wrong? Public Sub CallingTest(ByRef Source As Object) Dim D As mshtml.HTMLDocument = Source.document Source.status = "Working..." Dim H As String = D.documentElement.innerHTML() MsgBox(H) D.documentElement.insertAdjacentText("beforeEnd", "ThisIsATest") H = D.documentElement.outerHTML() MsgBox(H) Source.status = "" End Sub Function is called by this javascript: <SCRIPT> var EB = new ActiveXObject("MyObject.MyClass"); EB.CallingTest(external.menuArguments); </SCRIPT>

• Insufficient memory to continue the execution of the program

  - by Suman

  My Application (Vb.net, Access 2003/2007) is to scan Access Database files for activex controls and to generate report accordingly. Problem: Getting an error like: "Insufficient memory to continue the execution of the program." The above error occurs while scanning for older version of Access files like prior to office 2000. And the line of code where I get this is as follows: Dim oForm As Access.Form Dim oAccess as Access.Application oForm = oAccess.Forms(objForms.Name) But it opens the file and form as well. Need Help: Whether it is possible to read the file (Access Forms and Reports) or not? Please provide me reference or any solution.

• Asp.net error object not set to a reference

  - by Frank

  Hi all, Because I rush in development (a lot of whip cracking here) and declare my objects at the top of the function and instantiate inside my try-catch block, I get a lot of the good old "object not set to an instance of an object" errors while doing TDD, and later if I do miss a branch that object was used in (doing VB now, would prefer C#) or just in every day coding, object not set to an instance of an object is a bit vague. Sure the stack trace sends me to the line the error occured at, but it would be nice if I could modify my logging to either name the object or its type because sometimes I have multiple objects on the same line. It's not the end of the world, but in the end it would save me a few minutes each day. Any ideas on how I can pass the info on which object wasn't set? Thanks

• Not getting redirection to custom error page using custom errors - ASP.Net

  - by weevie

  Here's my Application_OnError event sink in global.asax.vb: Sub Application_OnError(ByVal sender As Object, ByVal e As EventArgs) Dim innerMostException As Exception = getInnerMostException(Me.Context.Error) If TypeOf innerMostException Is AccessDeniedException Then Security.LogAccessDeniedOccurrence(DirectCast(innerMostException, AccessDeniedException)) Dim fourOhThree As Integer = DirectCast(HttpStatusCode.Forbidden, Integer) Throw New HttpException(fourOhThree, innerMostException.Message, innerMostException) End If End Sub You'll see that if we've got an innermost Exception of type AccessDeniedException we throw a new HTTPExcpetion with a status code of 403 AKA 'forbidden' Here's the relevant web.config entry: <customErrors defaultRedirect="~/Application/ServerError.aspx" mode="On"> <error statusCode="403" redirect="~/Secure/AccessDenied.aspx" /> </customErrors> So what we're expecting is a redirect to the AccessDenied.aspx page. What we get is a redirect to the ServerError.aspx page. We've also tried this: Sub Application_OnError(ByVal sender As Object, ByVal e As EventArgs) Dim innerMostException As Exception = getInnerMostException(Me.Context.Error) If TypeOf innerMostException Is AccessDeniedException Then Security.LogAccessDeniedOccurrence(DirectCast(innerMostException, AccessDeniedException)) Context.Response.StatusCode = DirectCast(HttpStatusCode.Forbidden, Integer) End If End Sub Which unsuprisingly doesn't work either. Any ideas what we're doing wrong?

• MustOverride Shared Methods in .Net

  - by Ben

  Hi I have a few class's that inherit from a base class. I want to enforce that all of these Class's implement a shared method foo(). I am not able to create the following on the base class Public MustOvveride Shared Sub foo() as this is not allowed. I also cant create an Interface that defines a Shared Sub Foo() and implement that in my derrived class's, as this also is not allowed. Does anyone know how i should implement this? p.s i realise my example is in VB and i have also tagged C#, the same problem applies to both languages and presumably the same fix would apply.

• Prevent painting of .NET form while form is loading?

  - by dvcolgan

  Is there a way to turn off all visual updates to a .NET form while I am manipulating it? When my program first loads, for example, I set the tab control to the tab that was last open. The user can see the program switching tabs. I have looked into SuspendLayout and ResumeLayout, but either I don't understand what they are doing, or I am not using them correctly, because they don't seem to have any effect. Someone told me that there used to be a way to turn off paint events in VB 6. Does this still exist in .NET?

• How to prevent UI from freezing during lengthy process?

  - by OverTheRainbow

  Hello, I need to write a VB.Net 2008 applet to go through all the fixed-drives looking for some files. If I put the code in ButtonClick(), the UI freezes until the code is done: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 'TODO Find way to avoid freezing UI while scanning fixed drives Dim drive As DriveInfo Dim filelist As Collections.ObjectModel.ReadOnlyCollection(Of String) Dim filepath As String For Each drive In DriveInfo.GetDrives() If drive.DriveType = DriveType.Fixed Then filelist = My.Computer.FileSystem.GetFiles(drive.ToString, FileIO.SearchOption.SearchAllSubDirectories, "MyFiles.*") For Each filepath In filelist 'Do stuff Next filepath End If Next drive End Sub Google returned information on a BackGroundWorker control: Is this the right/way to solve this issue? If not, what solution would you recommend, possibly with a really simple example? FWIW, I read that Application.DoEvents() is a left-over from VBClassic and should be avoided. Thank you.

• Create DataGridView columns from Table values

  - by fireBand

  Hi, I am using data grid view to display items as excel spread sheet in VB.NET. I got a table named CostTypes with column names [CostTypeID, CostType] and values [1,External] and [2,Internal] (These are constant but more values can be added to table). I want to create columns with names of the values[External , Internal] in DataGridView. If I use databiding directly I get columns [CostTypeID,CostType] which is not what I am looking for. If some one could explain how to create columns at runtime in datagridview or how to retrieve data from data base using LINQ so that [External , Internal] turn out to be columns that would be great. Thanks in advance.

• Is it possible to have a Shared/Static Dependency Property?

  - by Matt H.

  [using VB.NET, but I can easily read C# code in responses] I have a class called QuestionClipboard with ALL shared methods/properties. I previously had a QuesitonClipboard.doesClipboardHaveContent function that returned true/false if there was a Object on my 'clipboard'. I'd prefer to implement a Dependency Property so I can allow this true/false value to participate in data binding. The "GetValue(dp as DependencyProperty)" method requires an object instance, which would mean that my Property CAN'T be shared! Here is what the code would look like in my perfect world... Of course, the word "Shared" before the property declaration renders this code useless. Private Shared clipboardHasContentPropertyKey As DependencyPropertyKey = DependencyProperty.RegisterReadOnly("clipboardHasContent", GetType(Boolean), GetType(QuestionClipboard), _ New PropertyMetadata(False, Nothing, New CoerceValueCallback(AddressOf coerceClipboardHasContent))) Private Shared clipboardHasContentProperty As DependencyProperty = clipboardHasContentPropertyKey.DependencyProperty Public SHARED Property clipboardHasContent As Boolean Get Return GetValue(clipboardHasContentProperty) End Get Set(ByVal value As Boolean) SetValue(value) End Set End Property

• Detecting a message box launched in another application

  - by richard-assaf

  I am developing a windows service, in vb .et, that launches a legacy application that performs some work. The service acts as a wrapper around the legacy app allowing users to automate an otherwise manual operation. Everything is working great, except occasionally the legacy app displays a messagebox. When it does this the process halts until the the message box closes. As the service will be running on a server there will be no user to close the message box. The service launches the legacy application in a System.Diagnostics.Process. My question is, is there way to detect that a message box has been displayed by a process that I have started using System.Diagnostics.Process and is there a way to through code to close the messagebox. I've tried to be brief so if you need more information please let me know. Thanks in advance Richie

• PDF Viewer Showing Last Page...

  - by steve

  I have a asp.net app that writes a pdf to file. Then, later that file is opened into a window (standard acrobat reader) for viewing. No problems there. The weird part... The entire document loads as it should, but the Reader initially shows the last page in the document on the screen. The user must then scroll up to the first page. It doesn't happen all the time (about 50%) and occurs across several test computers. Is there a switch in the code I'm suppose to use in creating the file or displaying the file to tell the reader to "start displaying the document on the first page?" Environment particulars: asp.net 3.5 vb, websupergoo's abcpdf.net pro 7 (assembly that creates the pdf file), Windows 2008 Server, IIS7 Thanks

• Registering a delegate function with an ISO C++ callback (on mono)

  - by Stick it to THE MAN

  I am thinking of wrapping ISO C++ code in C# class. The only problem so far is how to deal with the C++ callbacks. In .Net languages (C# and Vb.Net), I believe the callback equivalent. Sticking with C# for now, can anyone recommend a way that I can register the C# delegate functions with my ISO C++ code. The ISO C++ code is a notification library, and I want to be able to "push" the notifications to the mono framework (i.e. C# delegates in this case). My underlying assumption is that the mechanism/steps to implement this would be the same for the .Net languages - I'll just have to code the actual delegates in the .Net language of choice - is that assumption correct? Last but not the least, is the question of thread saftey. The underlying ISO C++ code that I am exposing to .Net (mono to be more specific), is both re-ntrant and thread safe - do I have to do anything "extra" to call .Net delegate from my ISO C++ code?
