Declaration Error Error Message For A Label Control That Already Exists?
May 25, 2009
I dragged and dropped a label control on my web form. But then whe I go to my VB .net code behind file, if I try and set a property on that label control, I am getting a "Declaration Expected" error message for the label I created.Yet if I do try and explicitly declare my label control, the compiler tells me that the label control is already declared.[code]

I have been working on an activeX control which works on serial port communication. Now I have completed the project and created its setup.exe using Visual studio 6 -> Tools -> Package and Deployment Wizard. Then I installed the control in another PC and in a new project included the control using project -> components. But when I click on the control in the toolbox and then include on the form it gives the following error : delete current link ? and on clicking OK, nothing happens. I tried searching a lot on google but didnt find anything. Another problem is that I have created a string array as a global array which can be accessed by all the methods.I am able to include the same activex control in my own pc when I have created the project. Here it works fine, I am able to access all the methods that I coded in the control, but the String array mentioned above can be accessed in other project. I tried writing Public before the array declaration but it give me the compile error : "Constants. fixed length strings, arrays, user defined types and Declare statements not allowed as Public members of object module."

I have 5 textboxes embedded in a datagrid that require a date format (mm/dd/yy), but can be left empty if user doesn't have date.User can poplute these textboxes for multiple records and hit submit button.On the submit i loop through the grid. If dates are populated AND they are in the correct format then I call a stored procedure that inserts the record into a table.If any of the dates that are populated in the textbox is not a date or in the incorrect format I need to display error message in a label.I got all this to work, but if it throws error message all the data in the grid is wiped out.How can i keep data in each textbox and still display the error message?

I made a web browser using the Visual Basic Language. I am having a problem with the WebBrowser Control.If I go to a website that runs scripts (i.e.; sports.yahoo.com), a message comes up:"An error has occured on this script page", Do you want to continue running Scripts on this page "yes, no". If you click yes or no, the same message appears for 8 more times. Is there anycode I can use to disable the "Script Error Message" from appearing in the WebBrowser Control.

I know it's possible in asp.net to create a custom error page in a web app, by putting the following line in the web.config: <customErrors mode="RemoteOnly" defaultRedirect="frmErrorPage.aspx" />
I have had to do this for my web app, since it is clearly much tidier than letting the program bomb out with it's ugly default error page. My custom error page just has the customer's logo and a brief message saying "Error has occurred. Please return to homepage"The trouble now is that I have no way of knowing what caused the error, when a customer reports it.
Is there a way to make the actual error message appear on this custom error page too?

I am trying to subclass the password recovery control in asp.net (4) so that I can override the behaviour of the OnVerifyingUser event but I'm having trouble adding my subclassed password recovery control into the page. I tried creating an asp:placeholder control and adding a new instance of my subclassed control to it but I just get an error that says "An entry with the same key already exists". I've tried doing this in the page_init and page_load methods but get the same error.
Here's an example of my subclass

I created a simple user control and everything went fine.Then I created another of the same control (as a different project) from scratch (creating the controls in a different configuration; but pasting code from the previous one from a text file).As far as I know I did everything the same for creating a user controlCreate a Class Library project Then Project>Add New Item> User Control Then delete the initial class that was added automatically (usually named Class1.vb) Put all of my code and components into the user control class.However, when I wanted to run it in the debugger as I did in the previous project, I now get an error message:"A project with an Output Type of Class Library cannot be started directly."

A client of ours reported that when trying to use our .NET .DLL in VB.NET they receive the error:error BC31429: 'OurClass' is ambiguous because multiple kinds of members with this name exist in namespace 'our.company.nspace' I've also been able to reproduce the error with a dummy project containing the single line of
Dim x as our.company.nspace.OurClass Normally this is because there are several types with names differing only in case. But in this case there is no such ambiguity. OurClass is a unique name not only in the specific namespace but in the whole assembly and any other assemblies referenced by the project. Reflector also shows this. There are also no class members with the same name, also verified by Reflector.
Also a weird thing is that the error wasn't there immediately after I created the dummy project, and then it suddenly appeared and now it doens't go away anymore. In fact I didn't even change anything between the two recompiles from which the first one worked, and the second didn't.
