Not through pure .NET, I'm afraid. You can use managed C++ and C# together to do this, search the web for more info.
Also, there are some C# serial port articles on codeproject; if you had a USB-to-Serial hardware, you'd be able to do this through managed code.

We have a third party application that handles some SQL management (SQL Server 2000). We do not have the source code or any documentation on how this application works.
In this third-party application, a user has to log on with some credentials and the application checks with a database if the username and password is correct.
I don't know if this is possible, but what I would like to do, is to create an application that executes a certain list of commands on the database whenever someone tries to log on within the third-party application. Since I don't have the sourcecode to the third-party application I have to write another one that executes parallell to this one.
My question is if it's possible for my application to know that the third-party application is executing a certain Stored-Procedure or a command. Are there any events/messages that I could catch?
Any ideas would be appreciated ...
Thanks

Hi i'm working on this control which exists of a
ParentControl -> containercontrol
ChildControls -> containercontrol
when i add the childcontrols to the parentcontrol the parentcontrol calculates the size of
the childcontrol all that works fine aswel in designer as in runtime
but when i add controls(eg button,...) with the designer in the child control they show good but when i click
the "build application" button the size of the controls in that childcontrol change they become much larger
(note i do set the anchor value but still the behaviour is abnormal)
i've been trying to find this problem for days now with no succes please if you have encountered the same problem or now a sollution pls let me know.
i attaches a sample of this behaviour you should.
build to see the behaviour
Sample
thx in advance.

|
|
|
|
|
did you look at the sample.
anchoring is not the problem here the problem is that the size changes when anchoring is set during build the size is back normal when you run the application.
if it where the anchoring i whould be glad but i also whould of found it by now then.
pls look at the sample if you want to help.

This functionality is not exposed through the current .NET framework class library. Use P/Invoke to call the Win32 SystemParametersInfo API.

If you're running VS.NET, simply right click on the Project file in Solution explorer and click "Add Web Reference". Give the URL (*.asmx file) and VS.NET automatically generates a proxy class that you can use in your application.

Ok, Ive have read many books and seen a lot of examples of how to bind a drop down list. So I am using VS .net and I use the IDE to create as much code as I can via the GUI. My problem is that the code generated does not match the code people use in examples of binding a dropdownlist. To be honest the examples I understand, the code generated by VS I don't understand but I want to. Any help appreciated.

Hey, I need some help to finish a project I am working on
I have a function that filters a database I loaded into a data grid it works like this:
private void selectRecordsDV()
{
string sFilter;
sFilter = String.Format("SalesDate >= #{0}# AND SalesDate <= #{1}#",xtBxStartDate.Text,txtBxEndDate.Text);
try
{
dvABC.RowFilter = sFilter;
dtGrdSales.DataSource = dvABC;
updateSalesInfoDV();
}
catch(Exception err)
{
MessageBox.Show(err.Message);
}
}
in a data view. I need it to filter one more column in the database named CustNo but can't seem to make it happen. any suggestions?

First of all, why the # ? Is this something I don't know about SQL ?
Secondly, what's the error ? That would help a lot in working out the problem. Is the text that's coming out in the proper format ? It should be in YYYYMMDD:HHMMSSSS, from memory.

As far as I am aware there is no simple way of changing the position of a tooltip in C#. By default it appears that the tooltip is painted below the control in question. I would like to be able to display it to the right of mouse pointer.
Tooltip appears to be sealed. Does anyone have any examples on how to hook the dll and inject this functionality? It's probably gonna be ugly -- but I don't think I have a choice 
Cheers

Hey folks,
Do you guys know how to read the names of application pools in IIS? Which API should I call?
Thanks a bunch.
|
|
|
|
|
IIS exposes much of its functionality through the iis:// directory service, which you can access using classes defined under the System.DirectoryServices namespace. Start by reading the ADSI/WMI property documentation[^] for the AppPoolId property. See Creating Applications Pools using System.DirectoryServices[^] for a sample that is close to what you require.

I have built a custom component that I use rather extensively but it has a "feature" that is not correct but I haven't been able to determine why. I converted one my Delphi components and merged it with features from several contributors here. I would like to thank all of you.
The basis of the component is as follows:
using System;<br />
using System.Collections;<br />
using System.Windows.Forms;<br />
using System.ComponentModel;<br />
using System.Text.RegularExpressions;<br />
<br />
namespace MyComponents<br />
{<br />
public class myMaskedEdit : TextBox<br />
{<br />
public enum InputMaskType<br />
{ None, Dollars, Number, Integer, Percent, Phone, SSN, Zip, Custom }<br />
<br />
public myMaskedEdit()<br />
{ ... }<br />
<br />
... Other Methods ...<br />
<br />
}<br />
}
I drag the component onto my UserControl and it looks something like:
using System;<br />
using System.Collections;<br />
using System.ComponentModel;<br />
using System.Drawing;<br />
using System.Data;<br />
using System.Windows.Forms;<br />
<br />
namespace PARTS<br />
{<br />
public class ucRMAHeader : System.Windows.Forms.UserControl<br />
{<br />
public ucRMAHeader()<br />
{<br />
InitializeComponent();<br />
SetupForm();<br />
}<br />
<br />
... Other Methods ...<br />
<br />
#region Component Designer generated code<br />
private void InitializeComponent()<br />
{<br />
...<br />
this.myMaskedEdit1.ErrorInvalid = false;<br />
this.myMaskedEdit1.FormatText = true;<br />
this.myMaskedEdit1.Location = new System.Drawing.Point(8, 48);<br />
this.myMaskedEdit1.MaxLength = 0;<br />
this.myMaskedEdit1.Name = "myMaskedEdit1";<br />
this.myMaskedEdit1.Size = new System.Drawing.Size(108, 20);<br />
this.myMaskedEdit1.StdInputMask = MyComponents.myMaskedEdit.InputMaskType.Integer;<br />
this.myMaskedEdit1.TabIndex = 214;<br />
...<br />
}<br />
#endregion<br />
}<br />
}
I can set all the properties correctly and the program will compile and run as intended. The above code is how it is seen in the program.
I then close the window for maintaining the form. I reopen it and the StdInputMask property is now blank in the property editor. If I look at the code itself, the property is shown as it is above. But when I recompile, the property is saved as a blank and the line is removed.
While viewing the code the error message The variable 'InputMaskType' is either undeclared or was never assigned. is shown in the task list.
What I don't understand is that the enumerated type has the public attribute and it does execute as expected up until the time you reopen the form.
Can anyone identify what I missed?
Thanks.
