Hi
I want to implement logging framework in a .NET application. The logs should go in a SQL Server database.
How can I do that? Any reliable sample links? Thanks in advance.

In a Windows Forms application we have a MDI area where multiple forms can be opened up at one time. Often the users want to toggle from one form to another and asked us to put some custom toolbar buttons similar to what you see on your web browser on the main application toolbar in order to achieve this behavior. I know that you can toggle nicely using the Control+Tab (forwards) or Control+Shift+Tab (backwards) Keys. However, I want to mimic that same exact behavior when the user clicks on the toolbar buttons.
I tried to achieve this by using the Activate() method on an individual MDI form after getting all of the MDI forms and determining which needed to be sent to the front. This works, but when you Maximize a single MDI Form and try to use Activate() it shows this distracting flashing when you are toggling between the MDI forms. Does anyone know how to fire the Windows key event for Control+Tab or Control+Shift+Tab from within the clicked event of a toolbar button?
Many thanks,
Lee

I guess you could try SelectNextControl on the MDI parent form (or is it the MDI client, I would guess). I don't know it if will work (probaby not), but try it.
If it doesn't work, you have the array of MDI children (in the MdiChildren property.) Find the current active child (ActiveMdiChild) in the array, and then ActivateMdiChild the previous or the next in the array. It's not so hard:
void SelectNextMdiChild(bool next)
{
if(MdiChildren.Length <= 1)
return;
From current = ActiveMdiChild;
for(int i = 0; i < MdiChildren.Lenght; i++)
{
if(MdiChildren[i] == current)
{
if(!next && i == 0)
{
ActivateMdiChild(MdiChildren[MdiChildren.Length - 1])
}
else if(next && i == MdiChildren.Length - 1)
{
ActivateMdiChild(MdiChildren[0]);
}
else
{
if(next)
ActivateMdiChild(MdiChildren[i + 1]);
else
ActivateMdiChild(MdiChildren[i - 1]);
}
return;
}
}
}I just wrote that code and didn't test it, but it should achieve your desired effect.
Good luck!

Hello, all!
I have 2 comboBoxes with the same itemCollection: Px, Py and Pz. They where built so that if I choose Px in comboBox1 the itemCollection in comboBox2 is only Py and Pz. To do this I created an event (DropDown event) for each of the comboBoxes that clears the itemCollection of the other comboBox and rebuilts it without the selectedItem of the comboBox that triggered the event.
This works just fine if the comboBoxes are DropDown, but it doesn't prevent the user from writing anything in the comboBoxes!
To make the comboBoxes readOnly I had to make them DropDownList, but when I click one of them the selectedItem disappears, wich means I can leave the comboBox without any selectedItem!
Any ideas on solving this problem? Or do I have to keep the comboBoxes DropDown and create another event (which one?) that prevents the user from writing anything in the comboBoxes?
Thank you in advance,
Patrícia Gonçalves

Hello!
You'll have to set the SelectedIndex property of the ComboBox whose items you've rebuilt afterwards.

mav

Thanks! I saved the selectedItem in a temporary string (t), rebuilt the itemsCollection and set the selectedItem of the comboBox to t.
Is this what you ment? Anyway... it worked! Thank you!

Hello,
I have:
foreach (DataRowView row in this.dataview) {<br />
for (int i = 0; i < row.Row.Table.Columns.Count; i++) {<br />
if (row["NumUnits"].ToString().Length == 0 || row["MonthsToService"].ToString().Length == 0) {<br />
<br />
break;<br />
}<br />
}
}
Is there a way of getting the index of the row within the IF statement?
Thank you
|

There is no built in function for that. Add a counter that you increment for each row.
---
b { font-weight: normal; }

Agreed. The IndexOf () is available in .NET framework 2.0.
You will have to iterate and compare to get the Row index.

Hello all
I have a Datatable, along with datarow and dataview defined:
<br />
DataTable dt = new DataTable();<br />
DataRow dr;<br />
DataView dv = new DataView();<br />
The Datatable is given these columns:
<br />
dt.Columns.Add(new DataColumn ("ID", typeof(string)));<br />
dt.Columns.Add(new DataColumn ("Antal", typeof(int)));<br />
dt.Columns.Add(new DataColumn ("belopp", typeof(string))<br />
After filling the table with data I make a view:
<br />
dv = new DataView(dt);<br />
... and then I sort it:
<br />
dv.Sort = "Antal DESC";<br />
My problem is, the sortin doesnt seem to work, when I print every row starting from the first I still get results like this:
antal<br />
2<br />
1<br />
2<br />
4<br />
4<br />
1<br />
6
Can anyone see what I'm doing wrong?
|
|
|
|

You must keep in mind that the DataView.Sort property will just sort the DataView and the underlying DataTable is not sorted. How are you printing thiese values
antal
2
1
2
4
4
1
6

yeah, im using the view and not the actual table to display data, so I dont think thats it. Here's how I do it (just for testing I might add  )
string temp = "";<br />
<br />
foreach (DataRowView dvr in dv)<br />
{<br />
temp = dvr["Antal"].ToString();<br />
}
and then I run debugger to see value of temp for every row.

I tried the code you have posted. It just works fine.

Thanks alot mate, since it worked for you too, I took a longer look at the code where I fill the table with data. I found
dt.Rows[counter].BeginEdit();
without any
dt.Rows[counter].EndEdit();
and that seemed to be the cause of it. Thanks again!

I am trying to create an array of classes however when I try to assign values to the class variables I get an error: "Object reference not set to an instance of an object"
Am I declaring my array wrong?
<br />
public class Form1 : System.Windows.Forms.Form<br />
{<br />
private System.Windows.Forms.Button btn_FillArray<br />
...
<br />
MyClass[] classArray = new MyClass[5];<br />
}<br />
<br />
private void btn_FillArray_Click(object sender, System.Eventargs e)<br />
{<br />
classArray[0].data = 5;<br />
}<br />
<br />
<br />
class MyClass<br />
{<br />
public MyClass()<br />
{<br />
data = 1;<br />
}<br />
<br />
public int data;<br />
}<br />
<br />
<br />
Thank you for the help - mutty
