Kill the COM+ stuff, move them to one server, and get them to talk to each other by importing the dlls that you build for the business and data layers. That's if you want to maximise speed. Christian Graus - Microsoft MVP - C++ Re: Spped up VB.Net application Rizwan Bashir8-Jun-05 22:48 Rizwan Bashir 8-Jun-05 22:48  Hello Prashant though you did not helped me out of sending dataset from remoting component to application but here are some suggestions for you. I had a COM+ application and it runs slow some times and some time faster I never knew why . what I did was the following 1. Used threads ... like I build Loadform procedure on every heavy form and used threading on it during load 2. Make that LoadForm procedure public and call it this way Dim frm as new form1 frm.loadform() frm.show use gc.WaitForPendingFinalizers gc.collect in finally tag for try so that there should not be any memory issue. as it often comes in these type of applications.. Actually your application needs optimization for the code and thats all. best of luck Re: Spped up VB.Net application prashant79_pawar9-Jun-05 0:48 prashant79_pawar 9-Jun-05 0:48  Hello RIzwan Thanks for your reply.My problem is not for specific form but for whole application when it loads under my menu.Actually when i load my application my menu gets loaded and under my menu, my forms gets loaded when i select any form my problem is 1.Its take time to load 2.its move up and down when it loads and this is case for every form alternetly so please understand my problem and suggest me the solution Regards, Prashant Prashant Pawar Re: Spped up VB.Net application Dave Kreskowiak9-Jun-05 4:15 Dave Kreskowiak 9-Jun-05 4:15  This is the first time I've EVER heard of a form moving up and down while doing some kind of processing. What is your coding doing during that process? Wiuthout knowing anything about your code, it's IMPOSSIBLE to tell you how to fix it.

I want to reflect it to get source code but I haven't tool to do it. would you help me? Thanks a lot Hung Nguyen Viet Re: Reflector Christian Graus8-Jun-05 18:50 Christian Graus 8-Jun-05 18:50  VB6 is not like VB.NET, it is not written in MSIL, if there's a decompiler, it's not a reflector. Christian Graus - Microsoft MVP - C++ Re: Reflector hungmitec8-Jun-05 20:06 hungmitec 8-Jun-05 20:06  Thanks for your advice! Agree that it's not a reflector, but I want to get the source code (by anyway). If you have experiences on this task, might you tell me about it? Re: Reflector Dave Kreskowiak9-Jun-05 4:13 Dave Kreskowiak 9-Jun-05 4:13  AFAICT, you can't. I haven't seen any decompilers for VB6 code. If you do find something, at best, you're going to get an approximation of what the source MIGHT look like, and it may not even work! There is no direct coorelation between the individual statements in the (machine code) .DLL and VB statements. There can be groups of (machine code) statements in the .DLL containing dozens of lines that amount to a single statement in VB. The problem is seeing that pattern in the machine code and know what it means. This is also complicated by optimizations that the VB compiler does to speed things up. It's not like doing the same thing with C/C++ code. VB is a higher level language compared to C/C++, which is more closely related to machine code.

Then it cannot be modified from inside datagrid but i want to allow deletion of row if 1 or more rows are selected and this is event raised after the delete button is pressed. How will i code this Re: how to delete rows in datagrid?tnx Dave Kreskowiak9-Jun-05 4:06 Dave Kreskowiak 9-Jun-05 4:06  You don't delete anything out of the datagrid. You delete the records out of the underlying datasource, then refresh the datagrid.

Printing HTML Code Adarsh Shah8-Jun-05 10:51 Adarsh Shah 8-Jun-05 10:51  How can I print the html code which I get as a parameter to the function. If I use "Printer.print" then it prints the html tags itself(ie......) But I want to print the output as it is shown in the web browser. Re: Printing HTML Code Christian Graus8-Jun-05 15:25 Christian Graus 8-Jun-05 15:25  If you want to print it as HTML, you need to print it from a browser. You can embedd IE in your app. Christian Graus - Microsoft MVP - C++ Re: Printing HTML Code Adarsh Shah8-Jun-05 20:09 Adarsh Shah 8-Jun-05 20:09  I will explain you the whole scenario. I have an asp page (say print.asp) which generates reports depending upon the id passed to it(print.asp?id=52). I want to print this document using the printer on the server where asp application is installed. For this I haev written an ActiveX dll in VB 6.0. So wht I'm currently doing is.... Reading the html of the asp page and passing the html code to the ActiveX dll.. I'm passing the html code to preserve the formatting of the page. DO you have any other ideas for this kind of Scenario. or may be as u mentioned in ur reply ... how to embed IE in the ActiveX dll. Thanks a lot Christian. Re: Printing HTML Code Christian Graus9-Jun-05 0:17 Christian Graus 9-Jun-05 0:17  Adarsh Shah wrote: how to embed IE in the ActiveX dll. I doubt you can, I reckon you need a GUI app to do that. I don't see how else you can parse HTML though. Why do you want the server to print it, can't you render it to a window on the server and print from there ? Christian Graus - Microsoft MVP - C++ Re: Printing HTML Code Adarsh Shah9-Jun-05 0:47 Adarsh Shah 9-Jun-05 0:47  ok.. 1) Can I open an IE browser from the activeX dll which will have the link to the asp page (ie print.asp?id=52). and then print it some way that doesn't ask for print prompt. 2) Or may be I can call a VB application with WebBrowser control and print it. 3) Or I found something: which blocks the print dialog box .. and I can specify the direct path of the print page Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long) a = Shell("rundll32.exe mshtml.dll,PrintHTML " & """" & temp & """") '""C:\a.html""") wnd = FindWindow(vbNullString, "Print") While wnd = 0 wnd = FindWindow(vbNullString, "Print") Wend Call Sleep(100) AppActivate "Print" 'PageCount SendKeys "{ENTER}", True I think the 3rd method is the best one... Any suggestions on this? Thanks again Christian.

Re: Printing HTML Code Dave Kreskowiak9-Jun-05 2:49 Dave Kreskowiak 9-Jun-05 2:49  1) Won't work. You don't have and can't put into your ASP.NET app, a Windows Form to host the control. 2) Will kind of work, but is a pain to work with. Since IIS doesn't interact with the desktop, the application is launches will never see the light of day. 3) Best option and least resource intensive. I can see a couple of pitfalls if your code is not written correctly. When you save the HTML to a file to print, make sure your code gets a temporary filename from the system (there's an API for it, but I can't remember what it's called off the top of my head). Also, you MIGHT have a problem with FindWindow, since this is dependent on having one. No desktop, means no window. Whether this works will depend on IIS (I'm no expert on it.) You'll just have to try it. RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome Re: Printing HTML Code Adarsh Shah9-Jun-05 2:55 Adarsh Shah 9-Jun-05 2:55  I will try out the 3rd option and let u know how it went. Thanks a lot Dave. .config issues SamNasr8-Jun-05 10:02 SamNasr 8-Jun-05 10:02  I created a console app using vb.net called MyApp.exe. The application is designed to use MyApp.exe.config. However, I cannot read any of the values in the config file. I get blank/null values for strDBConn when I use either of the following statements. strDBConn = ConfigurationSettings.AppSettings("DBConnectionString").ToString or strDBConn = ConfigurationSettings.GetConfig("DBConnectionString").ToString What am I missing?
