After Creating VS.NET project, Form is blank
This issue applies to using VB .NET or C# .NET and one of the following:
- ASP Barcode Server for IIS – when performing ASP.NET project integration.
- ASP.NET Web Server Control – when used in Web Applications.
- .NET Windows Forms Barcode Control – when used in Local Windows Forms Applications.
In many cases, the form will not display because a reference to the .dll is missing. This may happen when a project is opened after the DLL has moved and sometimes occurs the first or second time the project is used.
Solution(s):
In order to reset the reference to the .dll in the form, use the following instructions.
- Check the .user file (if it exists) and remove any references in the ReferencePath.
for example <Settings ReferencePath = “” > - Place all DLLs used in the project in project directory; in the same folder as the .sln solution file.
- Delete references to the component DLLs such as “IDAutomation.Barcode” from Solution Explorer.
- Add references to Solution Explorer. This is performed by choosing Project – Add Reference, selecting the .NET tab and browse to the appropriate DLL that corresponds to the project.
- Add the barcode control to the Toolbox by right-clicking in the toolbox, select “Customize Toolbox,” then select the .NET tab and click on browse to locate the appropriate DLL that corresponds to the project.
- Click the “Save all” button.
- Close solution or project.
- Reopen the solution or project.
