Re: Form return value and interface question

Hi,

1. There are several prossibilities.
a) Show the Form as you would normally with ShowDialog and add a property to it so the result can be retrieved afterwards. This is like the built in dialogs of .Net work.
b) Define your own ShowXY function in your form which internally calls ShowDialog on himself and returns the wanted result:

public MyObject ShowMyForm(){
   if (this.ShowDialog() == DialogResult.Ok)
      return _myResult;
   else
      return null;
}

2. There are several way to do this. One is:

if (Array.IndexOf(t.GetInterfaces(), typeof(IMyInterface)) >= 0)
   Console.WriteLine("Interface implemented");
else
   Console.WriteLine("Interface not implemented");

Can forms return a value to, let's say the winmain function, or can something like SendMessage be used to send s message to another window's callback function? If so how?

Problem with InstallUtil

Hi all,

I've created a service that needs to log in a different log then the application log. Therefor I've added the following line of code:

System.Diagnostics.EventLog.CreateEventSource("ServiceOne", "ServiceOneLog");

But when I run the InstallUtil I can see that it automatically adds the eventsource in the application log.

Does anybody have an idea how to make sure that my logs are put in ServiceOneLog? Or is there a way to tell the InstallUtil to which Log he needs to add the source?

Thanks in advance,

Geert

Windows Forms Tab Control

Hi all,

I'm trying to select a tab from the windows form's standard tab control on right clicking of mouse button.
The mouse event args gives me the location of the mouse pointer.
But the tab control doesn't expose any method or property to get the tab on which my mouse
pointer is hovering.

Has anyone of you faced similar problem like this ? Or atleast it will be nice if anyone can show me a pointer towards solving this problem.

Hoping to hear from you guys...

Thanks and regards,

You might try this approach...

You can get the coordinates of each tab on the DrawItem event. If you could save those locations and sizes of each tab every time the tab control is drawn, then in the mousedown event you can identify which tab was clicked on by referring to your saved information.

Good Luck!

The way to do it is to iterate over the tab pages and for each one call TabControl.GetTabRect. If your mouse coordinate exists inside the returned rectange, set that tab to the selected tab.

Hi,
There is no need to use like instead of this we can use between. In addition of date we have to use timestamp also. I think this might cleare you.

char fields will not order dates as you think - they will order them using a text search, not a date search, you must store the data in a date field of some sort.

You can do:
select * from table where cast(myColumn as dateTime) between '2005-12-1' and '2005-12-31'
but that's for mssql, i'm sure there must be convert function in sybase

If you look at the OP's connection string, he's using an Access database.

You connection string you provided will only work with an SQL Server, not an Access database. You cannot use an IP address alone to get to an Access database. You must supply a fully qualified UNC path to the folder share when the database is stored:

    \\ServerName\ShareName\folder\folder\folder\database.mdb
 
    or
 
    \\IPAddressOfServer\ShareName\folder\folder\folder\database.mdb

Appropriate Window Networking share security must also be setup on that share and folder, depending on the type of clients that will use the database.

Question about Office programing

TofuBug2429-Dec-05 20:37

Lately since upgrading to VS 2005 TS I've been playing around with the VSTO (the new version that ships with VS 2005) with much success and happiness. However I've run into what I think is a fundamental problem (and it may just be me but I have to ask)

I've created a couple C# Word documents and a couple C# Excel documents each has their own controls they are basically designed for automatic report's, receipts, etc generation without any user interaction.

Now I can run the Word or Excel "program" from VS and it works fine. Also I can open any of the Applicable documents in explorer and they work fine.

my problem is when I try to open them from another project the documents open but the controls are only visualy drawn none of their functionality seems to exist.

I've tried using the Process class to open both Excel or Word and the Documents themselves with the same results.

An example of one of the Excel documents i have is as follows:

when the Excel workbook loads it loads a non visable windows form (as a modal form to lock excel from user input) that when passed a single or a collection of Job's done to include the Job's Title, the hours spent and the Client's name the job was done for it then populates the spreadsheet with the values as well as calulates things like the total money owed for the hours worked, taxes, as well as things like populating clients into a dropdown list control for each job (when there are more than one client assigned to the same job) once the form is finished it closes returning control to the Excel workbook which then displays another windows form to save and or print the file (with a check box option to automate saving (by adding the date and time stamp to a generic filename) and printing.

So in my main program which holds several lists of jobs (which are housed in an sql server database) when the user selects one or a group of jobs from the DataGridView and selects the apropriate Generate Report File Menu option I need the program to load the appropriate Excel or Word document with the Controls intact so I can pass in the information needed.

I'm not sure if I'm completely missing something but I've googled and scoured msdn and i've yet to find an example of loading a compiled office project from another windows application so any help would be greatly appreciated

Thanks Everyone in adavance
