Re: File System Controls in VB for Excel

22-Sep-06 3:17

Without VB6, those controls don't exist. They come with VB6, so you'll have to get them off of a machine that has it installed. But, there may be a licensing issue here. I don't know if you'll be able to use the controls because of a possible designer license issue. You'll just have to try it and see. Copy the controls to the Windows\System32 folder, then register them using REGSVR32.

Printing from a website (ASP & JavaScript)

Hi,

I have an ASP page that draws up a report and display it to the user. If the user wishes to do so, he can click a "print" button which activates the printer dialog via javascript. This would be the same as if they selected "File > Print" from the browser menu.
My problem is that at hte top of the page, page numbers are added automatically, and at the bottom the URL of the page that was printed. Is there a way to get rid of this extra information, so that a "clean" document can be printed with only the results from the report.

Any help would be appreciated,
Thanks.
Mr.mark

Drop all the "Problem, Effect, Expected..." garbage and just ask the question.

Are you seeing this with all the controls or just certain ones, which ones? Which version of VB.NET are you using? Are the controls snapping to a grid if you move them around with the mouse?

installation headache

ihe22-Sep-06 1:26

22-Sep-06 1:26

I am working on a complex project. To make it easier I decided to produce some components in 4 different namespaces. These components were later imported in to the main project with an import statement at the top of the main project.
The program works well and i was considering writing all my projects as classes and components until this afternoon when i decided to deploy.
I produced the installer without error. I was able to install in another computer but the program just would not run in this second computer. The error message was
Processid=0x5e8(1512), thrad id = 0x2dc(732)
what does this mean and what did i fail to do.?

It sounds like your .DLL's for your components didn't get added to the installation, or are not installed where the Loader can find them.

Why are there two .DLL's with the same name in your Setup Project?? Where did both of them come from and where are they being installed??

If you're app is using 4 different library .DLL's, I only see one in this project. You're missing 3 of them. You'll have to straighten out your duplicate .DLL problem and add the other three missing assemblies to your Setup Project, at least.

Because of the difficulty I experienced I decided to rewire the program a little
The original Windows Application had 4 Windows Control Library it needed to function properly.
I decided to lump all the user control inside a single WindowControlLibrary.
This is what I did:
I created a project in vb.net using a WindowsControlLibrary I called it NAWADriLCiLibrary.

It houses several user controls that are all used in a WindowsApplication1 I call DriLCalLc.

The database is in MS Access and is called Hydraulic.mdb
The database is in the window application.

The command buttons to save, edit, delete into the records of this hydraulic database are in the window application. These buttons are linked to methods and property of the user controls in the windowControlLibrary.

In my developer PC after I have produced the NAWADriLCiLibrary I build it, using the build menu – build solution on top.

Then I copied the NAWADriLCiLibrary.dll generated from the NAWADriLCiLibrary/bin/ NAWADriLCiLibrary.dll into the DriLCalLc folder. After this I set a reference in the code of DriLCalLc pointing to this. I did this by right clicking the add reference and selecting this .dll when the “add reference “box came up. To enable me use it in my code I then at the top of the code add an import statement

Imports System.Drawing
Imports System.Windows.Forms

Imports NAWADrilcALclLibrary

Public Class Form1

End Class

What am I required to do? How should I produce my Installer?

Also thank you for your guide I will read the text at the hyperlink now.

Dave Kreskowiak26-Sep-06 2:09

Do not set a reference to the .DLL file itself. Make your control library project part of the same solution as your application. In your application project, set the reference to the control library project. Do NOT copy .DLL's into the bin folders of your windows app project. This will lead to "unable to find version errors", or problems where you make a change to the library code and can't figure out why the changes don't show up in your windows app.

To this solution, add your installer project. Pick the Setup Wizard to make this a little easier and make sure you add the Primary Output from both the Windows application and Control Library projects.

That should about do it...

This means that the machine needs MDAC 2.6 or better installed and it doesn't currently have that. It's a requirement of the .NET Framework so you have no choice but to upgrade it. You can get the latest versions here[^].

Then look into an obfuscation utility to make it harder to read. You can't encrypt it or make it the code can't be seen, but you can make it harder to read. The Professional version of Visual Studio .NET (and higher) comes with Dotfuscator, Community Edition. You can buy the Professional Edition, but I don't remember what it costs.

ihe wrote:

You can add a Merge Module to the project to get rid of the warning. Right-Click your installer project name, click Add..., then Merge Module... In the list that comes up, find dotNETFXRedist_x86_enu.msm and click on it, then OK.

ihe wrote:

The same way we any of the .NET Framework classes. Your .DLL (assembly) is just another set of classes. The developer adds a reference to your .DLL, then either imports its namespace or adds your control(s) to the toolbox.

I don't know if this would work, but if you were to hide the folder and create a shortcuct to your program with the shortcut named the folder name and the folder icon. So when the user clicks on the what they think is the folder, it opens your program, and say, if your program is already open, it just redirects to the folder or something.

This is information that should be passed into the method by the caller. Since your .DLL can't determine what type of application is calling it, Application.StartupPath might not have any meaning.

But, if you're absolutely sure that the only thing that will call your method is a Windows Forms app, you can add a reference to the System.Windows.Forms.DLL, then do something like this in your DLL code:

Imports System.Windows.Forms
.
.
.
Dim path As String = Application.StartupPath

I don't see any error in this statement. What makes you think otherwise ? What error are you seeing ?

wait - operator is probably a keyword in VS2005, which means it's a word ( like string or dim ) which has special meaning in VB and so you can't use it for a variable name. Try calling it op instead or something.
