Hi,
I am looking to (hopefully quite simply) populate a drop down list with a
list of the currently open windows (applications) and their respective
HWND's
I have found various snippets using GetWindow and FindWindow from user32.dll
but have been unable to get it all working.
Any help / code examples would be much appreciated. Preferably in C# but any
examples would be useful.
Thanks in advance,
Robin

Hi, I've done this (for getting a mirc window and sending it a message), but the code is pretty lengthy. Email me web@sloppycode.net if you need it.

I'd like to create a simple XML browser that displays a XML file an similar way as IE does. I'm not doing anything with the file, just want to display it in a readable way.
I have tried with xmlreader and richtextbox classes but not really been successful in formatting the XML in a nice way.
reader = new XmlTextReader(xmlfile);
reader.WhitespaceHandling = WhitespaceHandling.None;
// Parse the file and display each of the nodes.
int curr = 0;
int next = 0;
while (reader.Read()) {
curr = reader.LineNumber;
richTextBox2.AppendText(reader.Name);
richTextBox2.SelectionColor = Color.Blue;
richTextBox2.AppendText(reader.Value);
richTextBox2.SelectionColor = Color.Black;
if ( curr > next ) next = curr;
else richTextBox2.AppendText("\n");
}
Is this the right way to go, or should I start looking at other solutions?

If you want something really simple and quick, just embed the web browser into your application and then navigate to the xml file.

Well, I was advised to use the webbrowser COM component and that was it.

You need to hide the date last run somewhere, and see if it ever goes backwards

Don't uninstall the information that tells you the software has already been run here.

Generate a unique key that identifies the machine, get it from the customer, and use that in generating/validating the key you send back. That's what Microsoft does.

Hi Sanjay,
thanks for your reply, that really gives me some idea of what to look at, but still, cannot really get it work, below is the code I wrote trying to change the password. The first approach didn't throw any exception, but it doesn't work, the database keeps the original password. The second approach throws an exeception "Object or provider is not capable of performing requested operation." of type 'System.Runtime.InteropServices.COMException'. Any idea how to get it work? btw, I've also looked at the JRO one, which seems to work, but haven't tried yet cos some says JRO should be replaced by ADOX, etc.
private void ChangeUserPassword(String strOld, String strNew) {
ADOX.CatalogClass cat = new ADOX.CatalogClass();
ADOX.User user = new ADOX.UserClass();
ADODB.ConnectionClass dbConn = new ADODB.ConnectionClass();
dbConn.ConnectionString = @"Provider=Microsoft.Jet.OLEDB.4.0;Jet OLEDB:Database Password="+strOld+@";Data Source=C:\temp\db1.mdb;Persist Security Info=True";
dbConn.Open(dbConn.ConnectionString, "", "", -1);
cat.ActiveConnection = dbConn;
user.Name="Admin";
//First try
user.ChangePassword(strOld, strNew);
//second try
//cat.Users[user].ChangePassword(strOld, strNew);
Console.WriteLine("password changed");
dbConn.Close();
}
Many thanks.

Hi all,
I have written an app with a user level, business level and data level tier. I originally designed the app to be used across the network so that the business and data tier 'lived' on a server.
I am not sure on what is the best way to handle updates of the three parts of the app. I was thinking about having the user interface call the business level but if I update the business level will that break the connection with the business level.
The other way I have seen this handled is to run from the server in the same directory and then just create a new directory for each update.
Any thoughts would be appreciated.
Thanks

hi there ,
how can i put data from datareader to datagrid ?
|
|
|
|

You can't bind Windows Forms Controls to a DataReader object. However, you can bind it to a Web Form's Controls such as the DataGrid
Anyway,
To Bind to Web Control, check
http://www.easerve.com/developer/tutorials/asp-net-tutorials-datareader-datagrid-vbnet.aspx
To Bind to a window control, you would need to convert DataRedaet to dataset and bind dataset to dataGrid
Check getting reader from dataset at

The print preview showed two pages with text but after clicking Print on the print preview dialog window, only one blank page printed out from the printer. Any clue?
Two methods below:
private void btnPrintPreview_Click(object sender, System.EventArgs e)
{
try
{
streamToPrint = new StreamReader("C:\\Test1.txt");
try
{
printFont = new Font("Arial", 10);
PrintDocument pd = new PrintDocument();
pd.PrintPage += new PrintPageEventHandler(this.pd_PrintPage);
PrintPreviewDialog aPPDialog = new PrintPreviewDialog();
aPPDialog.Document = pd;
aPPDialog.ShowDialog(); //this shows up the print preview dialog window!
}
finally
{
//streamToPrint.Close();
}
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}
return;
}
private void pd_PrintPage(object sender, PrintPageEventArgs ev)
{
float linesPerPage = 0;
float yPos = 0;
int count = 0;
float leftMargin = ev.MarginBounds.Left;
float topMargin = ev.MarginBounds.Top;
string line = null;
linesPerPage = 75;
while(count < linesPerPage &&
((line=streamToPrint.ReadLine()) != null))
{
yPos = topMargin + (count * printFont.GetHeight(ev.Graphics));
ev.Graphics.DrawString(line, printFont, Brushes.Black,
leftMargin, yPos, new StringFormat());
count++;
}
if(line != null)
ev.HasMorePages = true;
else
ev.HasMorePages = false;
}
Any idea what went wrong or what was missing in my code? Thanks.

I have a solution with 11 C# projects in it, and after importing the solution into Visual Studio, I'm getting about 800 compiler warnings saying "Load of property XYZ failed."
The MSDN documentation for this warning is found here, with a suggestion that the project has been edited by hand (not the case though). Has anyone else seen this Visual Studio problem?

Not yet, but there is a reason why it is beta software.

hehe true true, but even VS 2005 Express beta didn't have these problems.
I've also noticed a bug that occurs occasionally where after clicking the main menu of VS, then moving the mouse to the Project bar, VS freezes up, which also didn't happen in the Express version. However, I'm wondering if all these warnings regarding invalid project properties is what's causing the latter freeze up.

The Project menu item freeze up, yes. The 800 warnings of bad project file settings, no. I have the feeling the two are related though.

It is unlikely you will get a great deal of responses in this forum. If you are in the official beta program then you should post your question on the private beta forum. If you are just running the public build of the product, then you should go to the public microsoft news group for VS2005 and post it there.
Those two forums will give you the highest possibility of feedback.
Also -- if you are in the private beta group, you just did something that would get you banned from the beta. The NDA states explicitly no public comments to be made of what occurs within the beta.

I'm running the public build so I'm free to make public comments.

Does anyone know how to do the Ghost window feature, that can be seen at:
The look can be accomplished simply by setting the Opacity property of your form to the desired amount.

"If the layered window has the WS_EX_TRANSPARENT extended window style, the shape of the layered window will be ignored and the mouse events will be passed to the other windows underneath the layered window." But it does not seem to work....
What are you doing? Have you tried to override the CreateParams and or'ing the WS_EX_TRANSPARENT (0x00000020L) window style?
