Re: Memory Problem mtone9-Jun-06 12:17 mtone 9-Jun-06 12:17  What is the affect on the system if that number continues to grow. Like you said it is reserved but doesn't that have the same kind of problem as memory usage, if it keeps taking up the reservations on the heap. I downloaded ANTS Profiler (trial version) and trying to look at it this way. initially it looks the same ( using memory up ) but I need to use the tool more so I can understand what I am looking at better. Thanks Dave. Re: Memory Problem Dave Kreskowiak10-Jun-06 2:42 Dave Kreskowiak 10-Jun-06 2:42  The .NET CLR will hold onto the memory until either your application allocates more objects or Windows wants memory. In the later case, the CLR will release blocks of memory back to the system until Windows in happy. The .NET Garbage Collector does a really good job of managing memory for you. Now, that doesn't mean that your app isn't allocating objects and not releasing them! That's where the Profiler comes in handy. It takes a bit of reading the documentation to figure out what you're looking at. Dave Kreskowiak Microsoft MVP - Visual Basic starting my service bhb189-Jun-06 1:52 bhb18 9-Jun-06 1:52  I wrote with VB.NET a service (with sample). It works perfect on the computer where I develop. I can install that service on another computer (with serviceInstaller), but after "net start" I get the error 2186 "Service is not responding to the control function". When I start it from the service windows I get the error 1053. What wrong? Or where can I find a full description of implementing and installing a service?

Angela Re: VB conversion tool Dave Kreskowiak10-Jun-06 2:48 Dave Kreskowiak 10-Jun-06 2:48  Yeah, just open the old VB6 project in VB.NET and it'll automatically launch the conversion wizard. It is most definately NOT a perfect conversion. In most cases, I would recommend just rewriting the project from scratch or converting parts of the app and rewriting the remaining pieces of it. The conversion process does NOT take advantage of the true OOP capabilities of VB.NET, nor does it convert every object into an equivilent .NET BCL object.

Thanks for your guideline and recommendation angela how can we change the propertis of pdf files [modified] vaibhav_2k69-Jun-06 1:01 vaibhav_2k6 9-Jun-06 1:01  Hi, how can we change the propertis of pdf files using the VB interface.By changing the properties i mean embedding the digital signature into the file,adding the watermark in the background,disabling the the file for printing,and other security features.All this is to be done using Visual Basic interface. Plz help me with the code Thanks -- modified at 7:10 Friday 9th June, 2006 Re: how can we change the propertis of pdf files [modified] Dave Kreskowiak9-Jun-06 1:27 Dave Kreskowiak 9-Jun-06 1:27  Since VB, or any other programming language, doesn't know anything about the format of a PDF file, you'll need some kind of 3rd party component to handle manipulating the .PDF file for you. I don't know of any specific components off the top of my head, but they do exist. Most notably Adobe would have the SDK tools you need. But I think their developer site is subscription based. Last I checked anyway...

Re: how can we change the propertis of pdf files Dave Kreskowiak13-Jun-06 12:12 Dave Kreskowiak 13-Jun-06 12:12  I've never touched Adobe's SDK and don't know anything about it. The best source of information would be Adobe's support. Dave Kreskowiak Microsoft MVP - Visual Basic running a program on a server Bis19829-Jun-06 0:19 Bis1982 9-Jun-06 0:19  hi, I need to run a VB.NET program on a server. What security policies do I need to set to run a program that uses a MySQL DB? Also do you need to make a strong name or can you just set the all code condition? Hope any one can help Kris Re: running a program on a server Dave Kreskowiak9-Jun-06 1:25 Dave Kreskowiak 9-Jun-06 1:25  There's really no difference between running your code on a Server version of Windows and a Workstation version. Setting security options would depend nearly entirely on what your application is doing and what resources you want it to have access to and under what user accounts. This is by no means trivial, meaning setting an option here and there. There is a bunch of planning that goes into this because there are just so many considerations - code access security, users rights to resources, database security, ... There's just too much to go into in a forum post. You can start with the .NET Developers Guide and the section on Code Access Security[^]. And no, you don't HAVE to make a strong name for anything, but depending on your application and requirements, it might just be a good idea. Dave Kreskowiak Microsoft MVP - Visual Basic Re: running a program on a server Bis19829-Jun-06 2:36 Bis1982 9-Jun-06 2:36  hello Dave, I copied the directory to the server and tried to run it. But I get a security exception. The given exceptions are: An unhandled exception of type 'System.Security.SecurityException' occurred in fichebeheer.exe Additional information: Request failed. Unhandled Exception: System.Security.SecurityException: Request failed. at fichebeheer.Form1.InitializeComponent() at fichebeheer.Form1..ctor() at fichebeheer.Form1.Main() The granted set of the failing assembly was: PermissionSet class="System.Security.PermissionSet" version="1"> IPermission class="System.Security.Permissions.EnvironmentPermission, mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e" version="1" Read="USERNAME"/> Doesn't this mean I need to set some permissions? Greetz Kris Re: running a program on a server Dave Kreskowiak9-Jun-06 10:30 Dave Kreskowiak 9-Jun-06 10:30  You'll probably have to relax Code Access Security for your app. Windows 2003 is locked down tighter, by default, than any other version of Windows out of the box.
