I am trying to get a 3rd party activex control which works in VB6 to work in Visual Studio 2005. Using the same exact code I am receiving an InvalidCastException error. Specified cast is not valid.
The code is as follows: AxQIChartControl1.DataTable =
"A-Filler"
AxQIChartControl1.Columns =
"Weight"
AxQIChartControl1.ChartType = 2

I have to develop an application using MS Visual Studio 2005 or above with the following objective:
* The application should allow users to create as many new forms as they want and each form should behave like a MS Visual Studio WinForm. By saying that it should be a container for drag and drop of controls from the toolbox that I will develop....
* Once the user design's each screen to his taste by placing various controls on the form, he should be able to save the form as a screen. Of course I have to provide functionality for each of the controls such as if he drags a button on to the form, he should be able to specify what action it has to perfom when clicked when the application is put into run mode. Quite similar to regular windows form button.
* My application should have two modes: a DESIGN MODE, where user can drag, drop controls and specify what they should do when put into RUN MODE. This is quite similar to MS Visual Studio designer.
* Last but not least is to be able to access the application via the browser with the same look and feel his desktop version.

Dim CustID As String = txtSrchCustID.Text
Dim FirstName As String = txtNewCustFName.Text
Dim SecondName As String = txtNewCustSName.Text
If CustID And FirstName And SecondName = "" Then
MsgBox("Please enter a term to search by")
EndIf
This returns "Conversion from string "" to type 'Long' is not valid." I was wondering what the error is and how it's possible to fix it? The other questions that I've looked at were mostly to do with variables assigned incorrect types, but I think that isn't the issue. It occurs when all of the variables are empty.
OK, this is going better, now im stuck in the mud again, i am trying to get a form to print,this works now, however i would like to enable a few frames with text boxes for a few seconds to allow the printer to print the text in black instead of gray. he error i am getting is this, as the timer disables:" Unable to cast object of type System.Windows.Forms.Timer' to type 'System.Windows.Forms.ToolStripMenuItem'.

View 4 RepliesI need some kind of structure where I can store data with a unique copy of each item (I mean that there can't be more than one of each). Something like the "set" type in the good ol' Turbo Pascal.
I know Visual Studio 2010 has the SortedSet data type, but I can't find something like that in Visual Studio 2005. Is there anything I can use for this purpose?
I am new to Visual Studio and (I am using Visual Studio 2005)I know how to connect/edit, etc to an access database by just using coding but I am having a problem with the Visual Studio Database wizard.
When I create a new Data Source and I specify a Microsoft Access Database File (OLE DB) connection + *.mdb filename, etc I am able to drag the table name onto the form and browse the contents of the database when running the application. No problem there.
The problem is when I run the application and adding new records to the database via the form, the new data does not get saved. I run the app (F5) + add new data to the database + save + then close the app. When I rerun the app from Visual Studio (F5), the new data is gone.
i would like to ask how am i going to add files with filenames that have non-English characters Also when i try to reinstall my application i get an error.Do i have to always change the version of the application in order to make an installation without errors ?
View 1 RepliesIs there something like the Reference property CopyLocal in a Visual Studio 2005 ASP.NET Web Site? A VS05 Web Application has a References folder in the Solution Explorer where you can select a reference and view its properties, such as CopyLocal, in the Properties window.But a VS05 Web Site only has a References folder in the Class View, where you can't access any properties for the references. Is there another simple way to set properties on your references in a Web Site? Or are the reference DLLs automatically copied when you publish a Web Site onto a machine other than your own?

View 3 RepliesAlright, I've been taking this class in school for Software development, and right now I am working on a assignment my professor is having us do, and honestly, I am kind of stumped here. Basically he wants us to create a form in Visual Studio 2005. It has a group box with two Radio buttons, (One for boys, One for Girls) and a List box that lists the corresponding names of the Gender you selected with a radio button.Alternatively, you can click the Report button and get the list that way.
Heres a screenshot of how he wants it: He wants us to use parallel arrays to make the list, each name has a corresponding M or F. So far I have the objects all set up, and the I have declared the parallel array like this in the Declaration of the form:
