Can we add a custom expression column to a Typed DataSet to display it in DataGrid? If yes then can you help me with that please? Thanks.
|

I have a boolean column in my database and I need my datagrid to show it as a check box insted of "0" or "1". Any ideas how i can do that?
I am using Typed DataSet to populate my datagrid. Thanks

I am displaying a ComboBox that hopefully contains the contents of a database table (a lookup of sorts). When the form loads, the ComboBox contains the correct values, all sorted. 
However, when I try to select a value programitically, I can't (well, I can't select the correct one). 
I create a dataset:
DataSet dsTitles = new DataSet("Titles");<br />
SqlCommand tableCommand = new SqlCommand();<br />
tableCommand.CommandText = "select TitleID, TitleDisplayText FROM tblTitles WHERE TitleHidden <> 1";<br />
<br />
SqlDataAdapter adapter = new SqlDataAdapter();<br />
adapter.SelectCommand = tableCommand;<br />
adapter.Fill(dsTitles, "Titles");
I then bind the dataset to the ComboBox:
comboBoxTitle.BeginUpdate();<br />
comboBoxTitle.DataSource = db.DataSetTitles.Tables["Titles"];<br />
comboBoxTitle.DisplayMember = "TitleDisplayText";<br />
comboBoxTitle.ValueMember = "TitleID";<br />
comboBoxTitle.EndUpdate();
So far, all is well. However, I can't seem to select the correct item. I've tried:
comboBoxTitle.SelectedValue = 2;<br />
Console.WriteLine("Current Title Index: {0} Text: {1} Combo Index: {2} Value: {3} Text: {4}", 2, db.LookupValueTitle(2), comboBoxTitle.SelectedIndex, comboBoxTitle.SelectedValue);<br />
TitleID of 2 matches TitleDisplayText of Mr, but nothing is visibily selected.
Current Title Index: 2 Text: Mr Combo Index: 0 Value: 2 Text: is what gets logged.
Any help would be appreciated.

Hi,
I've just owned an oldie Dual PentiumIII PC for low profile server and specially for programming.
I just want to take advantage of SMP for my apps and dual procs system really takes advantage from apps only if the apps is programmed to support smp. I don't know if there's a sentence that should be added in my code or is a parameter in the compiler command.
How can i add SMP supports in my C# apps?
Thanx.

Rewrite your app to include multithreading support. It's not something that can just be "turned on" with a switch.
Your application must be able to have parts that that run concurrently. For instance, breaking up a problem and having two threads each work on a seperate part of it. Or, in the case of say, a telnet server, one thread handles one client connection and another threads handles another.

Oh, i though it was as simple as turning a switch on with a special syntax in my code or a parameter in the compilation command.
So, you're saying that mi app will automatically detect 2 threads in my code and run each thread with a different processor?
In that case i should play a lot with System.Threading
|
|
|
|

No! You have to write your code to support multiple processors! Your code must be written to create it's own threads where appropriate. There is nothing that will do this for you.

Ok, i'll write my own threads inside my code.
System.Threading namespace is the way to go?
Do i have or can i specify wich processor should handle my thread?
|

Hi again, i've been surfing the net for a bit help and found code samples referring our topic in intel's site.
They use System.Threading for creating new threads (they have code that uses 4 different threads) but how do i know if these threads are handled by diferent processors? cause in the code they don't specify a processor to handle the thread and there's the possibility that a single proc may be running all the threads, how can i specify wich proc to handle threads?
Or my pc finds a thread and runs it with a processor and when my pc finds a second thread it runs it with the other proc?
Thanks for your help.
Sorry if i'm slow learning.

You don't! The system schedules which processor is going to handle which thread. Threads can even be moved between processors. 99% of the time, you really wouldn't have a reason to manually set the processor affinity. but, if you want to take a look at it, ProcessThread[^] in the System.Diagnostics namespace is what your looking for. Be sure to check out the ProcessorAffinity property.

<root>
<item />
<elems />

I need to move all the children and delete the parent, but i can't figure out how to do it. What do I need to do??

I have an MDI app with several child forms. The MDI form has a MainMenu control on it. My child forms also have MainMenu controls. By Windows defaults when a child form is opened in the MDI, the childs MainMenu is added to the MDI parents MainMenu.
How can I prevent this? I want the MDI forms MainMenu left alone. I need the child forms MainMenu controls to appear on them and not be merged with the parent MDI.
|
|
|
|
|
Well I found a solution for this. I wrote my own menu control. It works great so far and gives me more enhancement options then the standard Windows MainMenu.
In your face Microsoft standards.

I’d like to ask you a question: there are a lot of web sites made in static HTML. Sooner or later HTML sites are to be converted in PHP/MySQL, but the operation is very expensive since it is to be done manually or with the usage of ad hoc written software.
I’ve an idea to make an universal software to convert html pages into templates and database…
It’s really easy: it’s enough to compare two HTML files and make one regular expression that matches them. Then you refine that regular expression to match a group of files.
Example.
First file
1
Second file
2
Reg exp = \d
Third file
Reg exp = \d?
Fourth file
11
Reg exp = \d(0,2)
Fifth file
error
Reg exp = .*
|
|
|
|
|
And the question is?
---
b { font-weight: normal; }
|
|
|
|
|
Is it possible to make a software that compares two or more files that gives a regular expression that matches them all?
|
|
|
|
|
Yes, of course it is.
The question is rather if the pattern will be good enough to be useful for anything.
---
b { font-weight: normal; }
|
|
|
|
|
I think it depends from the number of file you can compare. However for web it would be enough to create a very very simple regular expression: .* (or better .*?) for any difference and the string itself for any identity between files.
example:
file 1:
1
file 2:
2
Reg Exp:
(?nome1 .*?)
Is it possible to do something similar modifying code from program that compare differences between files?
