I have a pdf file. I want to use visual basic code to print the file to another pdf, with my particular pdf settings, which includes
- orint in landscape format and
- print multiple pages on single page. (4) are there any libraries. is it possible?
Can System.Drawing.Printing Namespace do it? Is there any way to set that print multi pages =4 in PrinterSettings I was unable to find ...what all values print settings can take?
I have a Visual Basic Class Library project. It generates a DLL. Is there a method to generate a static .LIB to which I can do a static link?Alternatively, can I do a static link against a DLL?

View 12 RepliesI have two projects; A and B, where B needs to use some classes that are in project A. Hence, I added B to A's solution, and in B I added a reference to project A.
Is that sensible? Or should I rather put those classes in a class library?
I see that if I further want to open form/program B from a menu option in project A, then A needs a reference to B. Which would not be possible if B already had a reference to A. However if I use the class library for the common classes, then it's ok as B doesn't need the A reference.
Does this sound logical? It would be nice to know what are typical reasons for putting projects in the same solution, and if it's advised to use libraries aggressively to refactor common code between two projects, even if it's just a couple of classes.. Yet I've never made my own library, so a bit unsure on when to use it.
I have a DLL library, but I am not familiar with it. How can I get its usage in vb.net?
View 2 RepliesI was looking at tutorial that was detailing how to Build a Class Library Component and Consumer Client Application. One of the steps involved was how to add a reference to a library. Am I right in assuming that the reason for adding a reference is to show Vb where class library is located. I would also like to know if it is possible to add the reference within the code. In the tutorial the reference was added via the top menu (selecting project and add reference).
View 4 RepliesI am running through an issue for which I am unable to find a solution.My goal is to:1- compile a x64 .NET library (vb) which has a simple User Control 2- Use this dll in a .NET WinForm application targeted to x64 CPU ONLY.
I have been able to do the first step, but now I am unable to add the library into the VisualStudio Toolbox. With our previous x86 version we had just to right click to VS toolbox, click on "Choose items...", then brows to the needed x86 assembly. If we do the same selecting a x64 lib (of course I am running vs on a 64 bit OS), we get the following message "[DLL PATH] is not a Microsoft .NET module."
I have decided that I want to learn a bit about sound and how it works so I thought that I would make an application that reads and plays MP3 files. I know that this will be very difficult and that I will be re-inventing the wheel, but it's all for the educational purpose. So my questions are; How does it work, how does Windows Media Player plays the data from the MP3 file? How can I, with the data provided in the MP3 file, know what to play, how it should sound? Which method would I have to approach to play the sound provided in the file? If you think that I have too little knowledge on the subject

The way I know how to do it will require them to manually select the database EVERY TIME they call a function..

I'm merging two of my projects that can share a lot of the same classes into one solution with two web applications and a shared class library.
I've literally just dumped all the classes into the class library project and as expected I've got a ton of errors to fix. My main problem at the moment is the connection string. Currently I have this (which is obviously not going to work):

I have the following problem. I have some project written in Visual Basic (not Visual Basic .NET but simple Visual Basic - sic!). I can compile it and generate a dll. Then inside my web application I add reference to this dll library. When I run my web application hosted in default Visual Studio server, everything is fine and I can debug my Visual Basic project. However, when I host my web application in IIS then I can't.Code does not stop in my breakpoint. My asp.net catch the exception when I try to execute some method from the mentioned library which is something like:
Unable to cast COM object of type 'xxx' to interface type 'yyy'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{4C2875B5-3265-306B-9C74-1BEC98986B1A}' failed due to the following error: Error loading type library/DLL. (Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRARY)).
I am working on a project that currently uses a .tiff, compares the defined template document to the document in question. We are moving away from the .tiff format for a variety of reasons but mainly because the new files will be coming in the format of PDF. I see two potential solutions to the issue. First convert the PDF to a tiff and use the existing code. Or second, use a PDF library that will compare the template PDF to the PDF that is received. Because the PDF that is received will basically come from an outside source we won't know for sure if it is text based or image based so the library or tool will have to be able to compare both.
View 2 RepliesWhen I downloaded my Visual Studio Express I also downloaded the MSDM Library (Express Edition) to have the extra resource. I just now got around to installing that. I was under the impression that this was extra content stored on your PC. I could not seem to find a way to access it from VS Express 2008 or find an exe to start it by itself. I searched the Internet and all I get is information about accessing the Online version of the MSDN Library. I do see an icon in VB Express that says MSDN Forums. Is this what I should be looking for or is there really local content I can access.. How does this work?

In my shop we currently develop what I would consider small to medium sized projects.We have been investigating the Enterprise Library and how it may be able to help us in development.I have particularly been looking at the Logging block and comparing it with Log4Net.It seems to me that the Enterprise Library blocks would be an extremely over-engineered solution for something like simple application logging.That being said. Are you using the Enterprise Library and on what size projects? What are your thoughts on the Enterprise Library as a whole?

View 2 RepliesI'm in the midst of developing a class library DLL for a third party application. On my machine, the developers machine, things are going along smoothly. I can compile/build and my DLL is loaded, and thus works as expected.
I've been copying the contents of the Release directory from C:Solutions...Release to C:ProgramDirectory. I realize now that my DLL is loaded into memory from the Release folder, and not the folder I copied it to.The point being of course, I want to distribute this third-party add-in to my users. And sure enough when I try that, presumably the DLL isn't loaded into memory and thus not available to the user, like it is on my machine.
I tried the first obvious thing and registering the DLL on the user's machine, but that failed."The module "..." was loaded but the entry-point DLLRegisterServer was not found." It's apparent I am missing some key step or caveat when it comes to developing this class library.

I`ve made a .NET component in C#. After that, i`ve created a class library in VB.NET and added this C# component and a couple of buttons to the library (creating another component now with buttons). So far, so good.The problem is: when i use this final component (vb.net class library), i want to link all MouseClick Events of its own components (buttons and C# component). In other words, when i add this final class library to my VB solution, it has its own MouseClick event. But when i click inside it doesnt raise the click event unless i do not click in the buttons or in the C# component inside it. I want to raise this event in the application wherever i click (inside or outside its own components).
View 14 RepliesMy objective is to take a .vb class file that is used on multiple local applications/web sites and convert it to a .dll file that would would be deployed to the servers that we use.The code all works, I can build my class library project with Visual Studios 2008 Pro and end up with a DLL.I can then drag and drop the DLL into any application or website and use it successfully What I'm missing is how to compile it correctly so it will do two things;
1. Get it to show up as a .NET component
2. Get it to NOT scream at me when I try to reference it.
I think part of my problem is that I've been looking up assemblies and dll's when maybe I should have been looking at component authoring.No, I don't want to just stick with the drag and drop into local bins. I might as well just copy and paste the original .vb at that point.
