Anyone know of a library/assembly that can be used to generate a PDF from within a .net application.I know there are free PDF 'printer' drivers that could be installed separately but is there anything that can do it directly from within the application? For example a DLL that I can deploy with my application.

View 2 RepliesLet's say we use NASM as they do in this answer: how to write hellow world in assembly under windows.I got a couple of thoughts and questions regarding assembly combined with c# or any other .net languages for that matter.First of all I want to be able to create a library that has the following function HelloWorld that takes this parameter: Name In C# the method signature would looke like this: void HelloWorld(string name) and it would print out something like Hello World from name To sum it up Create a routine in ASM ( NASM ) that takes one or more parameters Compile and create a library of the above functionality Include the library in any .net language Call the included library function Bonus features How does one handle returned values?Is it possible to write the ASM-method inline When creating libraries in assembly or c, you do follow a certain "pre defined" way, the c calling convetion, correct?
View 4 RepliesI am trying to import the GetWindowText in a VB.NET application.So based on other sites you just have to import the interopt service and add a DLLImport statement similar to C#. But somehow it is not recognizing the statement and getting a BC30001 (Statement is not valid in a namespace) compile error.
Here is the code I used.Imports System.Runtime.InteropServices
<DllImport("user32", CharSet:=CharSet.Auto, SetLastError:=True)> _Public Shared Function GetWindowText(ByVal hWnd As IntPtr, <Out(), MarshalAs(UnmanagedType.LPTStr)> ByVal lpString As StringBuilder, ByVal nMaxCount As Integer) As Integer End Function
A co-worker checked a very simple Visual Basic Visual Studio 2010 application into our version control system. When I checked it out and tried to build it I got the weird error below, which I am guessing has something to do with which .Net Framework the build is targetted towards and also which Framework I have installed.

View 5 RepliesI currently have a simple crystal reports application which generates a crystal report and in the built in viewer provided by VS2005. There is a drop down where you can select options to change the criteria of the report. I wish to convert this app to a windows executable which will take all those select options and generates pdfs based on the crystal report. the executable will be triggered by windows task scheduler...or maybe command line app?
Obviously this will be somewhat of a re-write. What would be the best way to start this as? a crystal report application or a windows application.
When I go to my project properties I can see the Assembly Name under the Application tab. Now if I click the Assembly Information button I see some other settings such as title, description, company, etc. I can get the name by doing: Assembly.LoadFile("c:\filepath").GetName().Name.ToString()My question is how can I get the title, description, company, etc. I have tried a few things but nothing seems to work. Also I was told that you can create custom settings. How would you do this and how would you access them?
View 4 RepliesASP.NET pros out there can answer this question. I have a single web application that contains a website and a web service - both have several assembly references in common (data access layer, utilities, etc) - however, recent changes made to the web service will require different versions of the common assemblies, versions that the website won't work with (in case you're wondering, the website is some legacy 1.x .NET code that explodes when using the newer version assemblies.)
allow my web service to reference one version and have my website reference another? I can obviously have only one version with the same name within the bin folder.(P.S. - It just dawned on me that I could probably compile and reference the common assemblies with a different name, and place those in the web app's bin folder - but that sounds really fugly...)
I work with VB.NET 2005 and I want to set the application EXE name according to a certain condition. For example:

and so on.

I created a simple appication that loads a local Crystal Report into the CrystalReportViewer and then exports that report to PDF. I am able to run this application on my own computer, but when I try and run it on another computer it just errors out. I had to import the Crystal Report assembly into the application so I could get it to properly work. According to the error message, it seems to fail on the Crystal Report import statement. I have tried to install a couple of packages from SAP, but none of them seem to work?

View 3 RepliesI have an application written in .NET 4.0 that i compile into a DLL file. I want to be able to use this DLL file in a Windows Forms .NET 2.0 application. I don't need the application to really interact much, except just passing a couple string values to the 4.0 DLL. The DLL is pretty much a bunch of Windows which i converted to UserControls and i just need to be able to reference them to display the UserControls from the 2.0 application without having to use a different exe and having to package them separately.
What is the best way to do this? Because when i try to add the reference to the DLL to the 2.0 application, it gives me and error saying the DLL is built in a newer version of .NET so i can't do it that way. Is this where a COM object would come in?

frmOdyssey is the main form, from which frmSearch is called. After the above processing, I want to go BACK to frmOdyssey to process the FilFilterGrid sub on the Grid defined on frm Odyssey. I will be assigning a new DataSource for the Grid, which will be "selected down" by the strFilter. The above code works with no issue whatsoever in "Windows Application" mode. However, if I switch to "Class Library" mode, I get
an error on the last line of the last Sub, telling me "Reference to a non-shared member requires an object reference". If I uncomment the "Dim f As New frmOdyssey" line, and change the "frmOdyssey" to "f" on the next line, the error goes away, but then the process doesn't work, because the "select down" does not happen. I don't know why, except that "logically" I don't want a "new version" of the frmOdyssey. I want to update the existing form.

Out of 70 users of my application 2 are getting the following message when they to run the application... That assembly does not allow partially trusted callers. The reason for the error is that by default .net applications run from a network location have limited permissions. You need to use caspol.exe to add the network folder where your application is being run from to the Trusted Zone. If you do a search on these forums you will find plenty examples of how to do this. It is fairly simple. It will have to be done on every machine that will be running the application and a simple cmd file can be made to do this. The only difference is that I've asked our service desk to install the application to the local C drive which I believe they did.
View 10 RepliesI am loading an Assembly using Assembly.LoadFrom() as the assemblies are located in a different path from Application Base directory.
Dim oAssembly As Assembly = _
Assembly.LoadFrom("C:\MyFolder\" + ddlXlate.SelectedItem.ToString() + ".dll")
And I consume a Type from that assembly without any problem:
oXML = CType(oAssembly.CreateInstance(sBaseType + ".XlateContainer"), _
XlateBase.XlateContainer)
However, the problem occurs when I try to use a Type from this assembly from within another method like the one below:
oComboBox.DataSource = _
[Enum].GetValues(Type.GetType(sType + "+ItemEnum," + sAssemblyName))
sAssemblyName is the one I loaded using LoadFrom() actually. After it said it cannot find the assembly, I used AssemblyResolve event which solved my problem :Subscribing AssemblyResolve event :
AddHandler AppDomain.CurrentDomain.AssemblyResolve, _
AddressOf MyResolveEventHandler
Event Handler Method:
Private Shared Function MyResolveEventHandler(ByVal sender As Object, _
ByVal args As ResolveEventArgs) As Assembly
Return Assembly.LoadFrom("C:\PSIOBJ\" + args.Name + ".dll")
End Function
And I thought maybe the error occurs because it cannot find a dependent assembly defined in assembly manifest file I loaded using LoadFrom() already but when I checked the args.Name, I saw it was trying to load same assembly and after that it worked without any problem. So basically a type in the loaded assembly cannot be found before the event adding change.
My old code was using AppDomain.CurrentDomain.Load() and Assembly.Load() methods and they were working fine without the AssemblyResolve event. I was able to reach types in dynamically loaded Assembly from every where within the same AppDomain.
LoadFrom() can find dependencies automatically within the same requested assembly path and that couldn't be problem as everything this dll needs was there. So at first it looked like a AppDomain problem to me as it looks like it seems it can reach assemblies from Load context instead of LoadFrom context and I am now using LoadFrom context.But now it seems I should pass oAssembly instance evertwhere to use any type from the loaded assembly?Doesn't it load the assembly where I can reach it everywhere (same AppDomain) using simple Type.GetType(...) method?
