View 3 RepliesReportViewer is a component I use frequently. Imagine my surprise in VS2010 when I find that a project MUST use the 4.0 framework choice or the toolbox will not display the component. I am trying to use a 2.0 project for compatability reasons. No matter how I try to reference the WinReportViewer it will not work unless I update the project for 4.0 framework.MS, I don't understand what this means for upgrade path for old projects being opened in VS2010. We are a VS2008 shop and it would be horrible to upgrade a bunch of projects to 2010 only to find that ReportViewer is no longer supported by 2.0 framework.

View 2 RepliesI am using a check box tied to a program settings. When I am in form designer my check box property is "unchecked", however, when I debug my program the checkbox is checked.
My value for my settings is set to false and my property setting is also false.
Using 2 forms how would I click one button, from another form? ie In VB 4,5,6, I would used to do it as:-
Form 1:
private sub Command1_Click()
msgbox "Say Hello"
End Sub[code].....
If I clicked the button in form2, it would automaticlly, click the button in form1. Do I, do it the same way in VB Express or has it changed?
Currently I have a background worker doing a bunch of stuff and if a condition is met, it throws up a MessageBox for the user to pick from an the background thread pauses like I need it to, however most of the time the Messagebox shows up behind the main form (which is on the primary app thread, the UI thread) and I'd like the BW code to pause until it's acknowlegded and I also want the MessageBox to be owned by the main form (so it's always displayed in front and you can't get to the main form until you acknowledge the MessageBox. Later I'll be changing the MessageBox to be a modal form that matches the app's theme (I'll be opening this form using .ShowDialog()) should I go ahead and make that form now?

View 2 RepliesI have a vb.net application that uses Flash movies (AxShockwaveFlashObjects.AxShockwaveFlash). I have buttons in the flash movie. When they first start using the application, they can single click on the buttons in the flash movie and button responds accordingly. But after a while (and I haven't been able to pin-point an exact thing that changes it or my issue would be solved), the user has to double-click on the button in the flash movie for them to work.
View 2 RepliesHow can I make a program so you click a button and select a File using a OpenFileDialog and click send on your computer and it will send the file to a different computer and then a SaveFileDialog will show asking where to save the file on the other computer. Oh ya I cant use WinSock or whatever becuase im using Windows Vista 64 Bit. I need it because I for some reason cant use printer sharing. It might be because im on A 64bit Vista Machine and I want to print a file off of a 32bit XP Home Machine.
View 6 RepliesI want to create a server control that inherits System.Web.UI.WebControls.Button but gives it special capability, now what do i mean? i want my button to be a confiorm button that will work like so:
Renders to the page as a button of lets say cancel after the user clicks it i want to catch the click event (within the server control) and now after the click makeing the button not visible and makeing some kind of content placeholder (that will render from the server control) visible. that content place holder will have 2 buttons inside of it: yes and cancel. I want the programmer that adds this control to be able to register a function to the click event of the yes button. and the second cancel confirmation button should make the first button appear agian. (i know how to do this all in the client side but this time i need it all as server events)
My question is this: how do i catch the click event? i want it all to be handled inside the server control itself. so a programmer that adds this control wont have to worry about anything but just needs to register to the click event of the "yes" button.
I am writing an Automation program to control an MS Acces applcation. Here is the sequence of events:
- Load MS Access Database (Done)
- Load an MS Access form (Done)
- Take dates from Main.VB and populate 2 fields in MS Access form (done)
- Load another MS Access form called Stage_2 (Done)
- Load a file name into a filed in the Stage_2 form (Done)
- Do a click event in MS Access linked to a button called Pre_Stage_copy on Stage_2 form (How do I do these?)
- Do a click event in MS Access linked to a button called Pre_Stage_import on Stage_2 form (How do I do these?)

1. Retrieving data from an .mdb
2. Displaying the table(s) in a datagridview
3. Populating an array of structures with the table data
4. Searching the array of structures for a member value equal to a string
5. Displaying the matching array elements in a listbox.
[code] Any suggestions? Am I missing something simple? Should I be using a Multidimensional array instead of a structure?
I have a basic window that has 20 buttons (One, Two,.....,Twenty).Currently if you click on a button its background color changes, and changes back on next click.I'm looking for a way to make it so when the mouse button is held down I can drag across the screen and it will change every button I hit.Disregard the "Shut Down", "Restart", "LogOff", "Clear", and "Invert" buttons. This idea doesn't apply to them.
View 5 RepliesI am trying to get all assemblies in CurrentDomain using AppDomain.CurrentDomain.GetAssemblies() to write their FullName into a DropDownList, however if I don't instantiate them, they are not seen in returned array from GetAssemblies() in CurrentDomain.They are all added as Reference and in Reference folder of the solution. Only time I can get them from the GetAssemblies() is when I first instantiate them.How to overcome this problem with an easy and more generic way instead of instantiate them everytime when I add new Assembly, etc.Due to company policy, I have to obfuscate some parts of the images: All the assembilies are referenced in Reference folder:

View 2 RepliesI am in the middle of (trying) to create a Class Library available for use in VB6/VBA. With some assistance received here I have now done the following:Created a Class Library Project in Visual Studio 2010 Express and put the code in a Class Module.Learned I needed this wonderful thing called an "Interface"... Made one of those:)I opened the project properties and went to "Assembly Information" and checked "Make COM Visible".I went to "Advanced Compile" options and targeted .Net 2.0 (it's very simple code).Removed all references expect for "System".Built the project (no warnings or errors) and copied the DLL out of the Bin folder into C:WindowsSystem32 Ran RegAsm /tlb. Everything seemes just fine.I popped open excel to run a quickie test and the TLB is available but I have two problems:
I can see both the class and the interface in the Object Browser/Intellisense.When I try to create an instance of either object (Set obj = New MyObj)I get the error:I can set a reference to the Object and the Intellisense can see it, I just get that error when I actually try to create the Object. Did I miss a step?
Is it possible to instantiate a new class object within a Form Procedure where it is accessible to all other Procedures/Functions within the Form Module? For example, I have a Client Class Module that contains properties and Methods that reflect a Client DB Table. All the properties and Methods within this class are Public. So, when I instantiate a new instance within a Procedure, I declare it as such:
Private Sub cmdNewClient_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdNewClient.Click
Try
Dim client as New clsClient
[code]....
Normally, I would declare a new instance of this Class Object at the beginning of a Form Module. I'm trying to do this in order to have more control.
We are having problems with the speed in parts of our application, Standard .NET 4 Windows forms application. We have a ListView containing some commerce items and the user can click on items to put them in a shopping cart. The problem is that when clicking 10 times fast on one item, only 4-6 items is added to the shopping cart.I get the same result when building a simple test application with only one ListView, with one item and a debug.print in the click handler.I have tried to add a Button in the same testapplication and this is fast..[code]
