• Windows Forms Splash Screen in VB 2005

  I have a Small question i used the preset splash screen that is available in VB 2005 now when i run my project it only shows the splash screen for about 1 second how would i go about controlling the time to show the splash screen before it to continue. Usually the reason for using a splashscreen is to show the user something while the main form is waiting to show due to preliminary processing for the application. The last thing you want to do is put the app to sleep. Use the My .Application.MinimumSplashScreenDisplayTime property. You can't set this in the Startup event. Set it in the New constructor for the SplashScreen before InitializeComponent(). ...Show All

• Visual Basic Best place to put application initialisation code

  Hiya, I'm trying to get to grips with using a VB2005 splashform. Where's the best place to put in initiliasation code, like loading in XML settings, checking DB connection Is it in the Application OnInitialize function, the splashscreen_Load sub or somewhere else I'm a little concerned in that the splashscreen will close after X number of seconds. How do you ensure that all the initialisation is done before it closes Many thanks John good one. Well it makes logical sense that if you are going to be initializing your form in some way, to place the code there rather than calling it from another method, since you create a "new" instance, it makes logical sense that ok, you ...Show All

• Windows Forms Thread Killing (That do some Extensive Work)

  Hi, I am intantiating thread that do more extensive work, i.e. executing query on FoxPro 2.6 through ODBCDataAdapter with VisualFoxPro driver. Since the query executing is Complex and navigating through 870000 records and taking a time about 2-2.5 minutes. Once the thread is started and goes for data retrival. Meanwhile if I try to close the form. The thread is still running. I have also added Code for killing thread in Closing event of form using Abort() method. But it does not kill the thread. Instead the threadstatus returned is AbortRequested. Please help me in this regard, as Closing event fire the thread should returned and leave the resources. Thanks Thank you Sir, After this long discussion I conclude that only way I use is ...Show All

• Internet Explorer Development Sharing data between different instances of BHO

  Hi I work in a single sign on system that uses a BHO to complete logins in IE. In IE6 everything worked fine, but now doesn't It seems that the data used to complete the fields isn't beign received. The data is passed throught a shared data memory area inside the BHO's DLL. The question is, with the new security changes, could be that IE7 doesn't allow sharing data between different BHO instances and a controlling app Each tab haves a BHO instance A BHO can send messages via PostMessage to applications I'm testing the BHO in a XP SP2 so no protected mode is involved. And I'm coding in VC++ Thanks a lot Sebastian To answer some of your questions: Yes, Each tab does have its own instance of the BHO. ...Show All

• SQL Server Best way to launch report from a C# Winforms app?

  I'm new to SSRS. I would like to launch a report from a C# desktop application, supplying parameters programatically. I was able to do this using System.Diagnostics.Process p ... then p.Start(@"(path)\iexplore.exe","(reportURL)"); I'm betting there's a much better way to do this. Ideally I would like to create an IE window that shows only the report, that is, only the report viewer toolbar is visible, the IE toolbars and menus are hidden. I want to specify IE as the browser in case some other browser is installed as the default web browser. Can anyone link me to a tutorial or provide a code snip Thanks. Alas, it is at present still a .Net 1.1 application. I'll use ReportViewer when I u ...Show All

• Visual Basic Convert a string to decimal (where punctation is [,] instead of [.])

  I am converting a string to a single, but I don't get the expected results when converting a string where the punctation mark for the decimal is comma. lets say the text is 6.5 Dim sngMyNumber As Single sngMyNumber = CSng(txtInputA.text) The result is the single number 6.5 .. SUCCESS :) But when the text is 6,5 (which would be a common punctation mark for my application) Dim sngMyNumber As Single sngMyNumber = CSng(txtInputA.text) The result is 65.0 and not 6.5 which I expect. Is there any way to instruct VB to handle [,] in the same way as [.] when converting strings to numbers I could of course handle the string before conversion, and replace any [,] with [.]. Before I do this, I'd like to know if there is any 'standard' wa ...Show All

• .NET Development .NET 1.1 vs .NET 2.0 behaviour with Image fields

  In not .NET 1.1 and 2.0 the System.Type mapping for a SqlDbType of Image is byte[]. If you use this type to create a SqlParameter (with a value of DBNull.Value) and then use this in a SQL statement of the form "Update table Set ImageField = @parm where ......" Then in .NET 1.1 it works, but in 2.0 you get an Exception "nvarchar is incompatible with image" How can you determine the correct System.Type to use for Image fields, and why is the behaviour now different The application code is generic and not tied to specific database designs. Thanks Tony Here is my sample code which will generate the error. Create a table with an image field, and update the ...Show All

• Visual Studio Express Editions Inherited forms: lost controls :(

  I have a base form A that has just the basic Accept and Cancel buttons, and some coded functionality for data base apps. When in the designer I create a new form B and by code I specify it inherits from A, visually I can see the two buttons coming from the base form, with the usual lock icons. My problem is when I run for the first time the program, in run-time the buttons disappear; when I go back to the child form using the designer, buttons are just gone....
