It's called SOS[^](Son of strike)

WinDbg is an advanced tool, not for beginners. You'll find some docs here:
http://www.microsoft.com/whdc/DevTools/Debugging/default.mspx[^]

A lot of what you can do in WinDbg can also be done via the command window in visual studio. For quick debugging and info this can be easier.

Debugging .NET 2.0 applications[^] by John Robbins has an excellent intro to WinDbg directly targeted at .net coders.

Thanks Simon!

I have using .load to load the SOS package. And I have tried I can use extension commands like
!threads.

But when I use bu or bm to set a breakpoint, for example, bu Foo (Foo is a function in class FooUtility), there is error message like -- "Operation not supported by integrated managed debugging.
". How to solve it?

Sorry, I've no idea what the problem is. I'm no WinDbg expert.

I'd recommend getting a good guide, like the John Robbins book and starting with a simple app.

DataGridView, CheckBoxes and ThreeState

Steven Kirk4-Jul-08 0:43

Hello,

I have a DataGridView with a DataGridViewCheckBoxColumn. I want to be
able to have the checkbox display in an indeterminate state, so I've
set the ThreeState property to True. However, I want the indeterminate
state to only be set programatically - whenever the user clicks the
checkbox, it should only toggle between Checked and Unchecked.

Now, this is the default behaviour of a standard CheckBox control - as
detailed in the CheckBox.ThreeState property documentation:

"the CheckState property value can only be set to the Indeterminate
value of System.Windows.Forms.CheckState in code and not by user
interaction"

How would I achieve this with DataGridView? I'm committing the changes
to the checkbox cells immediately by catching the
CurrentCellDirtyStateChanged event and calling CommitEdit as suggested
in the documentation for DataGridView. However, if I try catching the
indeterminate state in this event or in CellValueChanged, and setting
Value to CheckState.Unchecked, the cell's Value property changes but
the display does not update until the control loses focus or another
row is selected.

As this is the default for the CheckBox control, I'm sure it can't be
that difficult to get the DataGridView to do it. What am I missing?

Thanks in advance for your help,
Steven

Unique Problem, Connecting to web service using credentials fail for 1 user only, works for all.

Hi I have a desktop application with a back-end as web service. Web service is hosted on server with Windows Authentication option.

All users do settings in provided setting form using desktop application and hit test connection and it succeeds for all except one user. When this unique user click test button he gets 401: access denied message. if he copy that web service URL in web browser and enters same credentials as in setting forms it works. So only the application fails to connect with web service.

Any help would be highly appreciated to resolve this issue.

Check the text encoding.

BTW why not hook up the debugger and see what happens?

Hi
Thanks for reply. its our client and we cannot force/request him to install .Net on his machine for us. So what ever we can do we have to use our development machine and then deploy on his machine.
if Text Encoding would have any problem then it must be with all users.

That's a bad assumption! Your use could fail because it has a 'ê' in its name and the server translates it incorrectly.

hi it is not the problem, user has confirmed that his username is alphaNumeric like usr7980 and password is totally numeric. So encoding is no more applicable. Any other idea's

Best practice static class or static variables.

ESTAN4-Jul-08 0:18

Hi,

I have a question about static.

I have the following class:

public class Members
{
static public string Administrator = "A";
}

Because I would mark the variable Administrator as a Const, I changed the class to the following:

static public class Members
{
public const string Administrator = "A";
}

In my eyes, the behavior is the same in accessing the variable, only that you are not able to change the Variable.
Is this correct? Or do I need to use the keyword readonly instead of const?

Than I would have:
public class Members
{
static public readonly string Administrator = "A";
}

So, help me out by saying what is the best practice here.
Thanks.

The difference between read only and const is that one can be set in the constructor ( from memory ) A static class is syntactic sugar, the compiler just barfs if any non static elements exist in there. I use it, because it makes my intentions clear, but it really don't actually give you anything.

Problem with simple arithmetic using textbox and label!

Hi Guys,
What I'm trying to do is to update a label as numbers are being inputed in a textbox.
The label(lblBalance) is to decrease, or increase, as the value of the textbox(txtAmount) changes.
lastEnteredAmount is a string obj that holds what was previously entered in txtAmount.
lblAmtMax is a label that holds the max amount that the user can enter.
I put the code snippet below in the keyPress event of txtAmount. But i don't get the required result. What am I doing wrong? Confused | :confused:

//input validation already done here<br />
.<br />
.<br />
.<br />
<br />
if (double.Parse(lblAmtMax.Text) < double.Parse(txtAmount.Text) || double.Parse(lblBalance.Text) < 0)<br />
{<br />
    lblBalance.Text = "0.00";<br />
    txtAmount.Text = lblAmtMax.Text;<br />
    return;<br />
}<br />
<br />
//get diffce between amtEntered and last Amt entered then add it(positive or negative) to existing balance<br />
double diffce = double.Parse(lblBalance.Text) + (double.Parse(lastEnteredAmount) - double.Parse(txtAmount.Text));<br />
lblBalance.Text = diffce.ToString();<br />
lastEnteredAmount = txtAmount.Text;

Please help! D'Oh! | :doh:

It's okay to validate the character input in the KeyPress event, but the info in the text box property txtAmount.Text is not changed until after that event. You probably want to validate the character entered in KeyPress, and if it is validated do the rest of your code in the TextChanged event.
