I know about Pete's article, but a vague memory suggests that @Marc-Clifton wrote something similar.

One of the articles that Griff mentioned in his reply is this[^] one. In general, if you show that you've made at least some effort, you will find that people are more willing to help you. If, however, we feel that someone keeps posting questions that shows that they have put no effort into finding something out for themselves, they will quickly be labelled a Help Vampire, and will be ignored or, in some cases, removed from the site altogether. Really, that's all we ask; that you have at least tried to find something out for yourself.

I agree. We're splitting hairs now. I'm looking at Experts Exchange, as a possible resource. It never hurts to have several.

Not sure I agree. I find that the forum that works best is the one you feel most comfortable in. Many people swear by SO, and many by CodeProject, and many by others that I have not used. But as others have already said, think about what you are asking, and whether you could actually find the answer by using Google, reading a good study guide etc. I was late coming to C# (about 5 years ago) and there is still lots I don't know, but the articles here that cover the subject can answer most of my queries.

I'm on SO every day, however, I would not recommend that for absolute beginners. You'll be calling it quits after that experience if you don't really have a desire to continue, because answers were given in the context of the time when the question was posted. So I've been really discouraged after spending a great deal of time going down rabbit holes and spending money buying books on topics that have since become outdated.

IMO a forum is the wrong, erm, forum, as what you probably want is a more of a discussion of the pros and cons to different approaches, often including not just the technical discussion but help with evaluating third party solutions vs. roll your own.
As I've mentioned to others, I enjoy mentoring and would be happy to help. If this whole mentoring thing takes off with more than a few people, I might set up a Slack (or similar) site!

Yeah, something like that! If I worked with developers, I could just hit one of them up on Skype, but I'm a firefighter and don't have access to that now. It will be less important to me when I get a job in the tech industry again, but until then, I'm pretty isolated.

@RickBishop It seems to me that you have been getting good responses on the QA forums here. Have you accepted any of the solutions ? Do you respond promptly to queries that ask you to clarify your posts ?
Compared to StackOverFlow, CP is 1000% gentler, kinder

@BillWoodruff I'm very pleased with Code Project and I agree with you completely. I wasn't wanting to replace it. I was hoping for a resource to ask quick questions, nothing that requires digging through code and whatnot. Just ask for some quick advice, like "do you see this in the real world?" and "Is there an easier way to handle NULL values than == null?" stuff like that.

Hi Rick,
I think the kind of questions you mention are fair game for QA.
I hypothesize that some questions that appear simple are hard to distinguish from questions dashed off by folks who are looking for a quick fix for homework ... so many of those on QA.
Other questions that QA responders may see as being an indication that the OP is not engaging in basic research, is not taking the time to read the docs ... those questions, imho, may also get ignored, or dismissed with a quick reply.
For me, I know that anyone who shows responsiveness to my attempts to clarify questions in comments, or responds quickly, and in depth, if I respond with code or links to resources ... well, I am motivated to engage further.
cheers, Bill

I'm uploading files to a server. The FTP class reports progress:
foreach (var file in publishInfo.Files)
{
Progress<double> progress = new Progress<double>(x =>
{
ShowProgress("", x);
});
client.UploadFile(file.FileName, targetFile, FtpExists.Overwrite, true, FtpVerify.Throw, progress);
}
then...
private void ShowProgress(FileEntity file, double progress)
{
}
I need to pass the loop object 'file' to the ShowProgress method. How do I get access it inside the progress callback?
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.
Ya can't fix stupid.

I have a stored procedure like this
PROCEDURE PRC_ABCD_GETALL (resultset_out OUT TYPES.cursorType)
AS
BEGIN
OPEN
resultset_out FOR SELECT * FROM ABCD;
END PRC_ABCD_GETALL;
using (OracleConnection conn = new OracleConnection(cnn))
{
conn.Open();
OracleCommand cmd = new OracleCommand();
cmd.Connection = conn;
cmd.CommandText = "PRC_ABCD_GETALL";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("resultset_out", OracleType.Cursor, ParameterDirection.Output);
OracleDataReader rdr = cmd.ExecuteReader();
while (rdr.Read())
{
result.Add(Construct(rdr));
}
}
but I'm getting error 'OracleDbType' does not contain a definition for 'Cursor' in
OracleType.Cursor. Any solution for this??

Hi,
I'm not familiar with OracleDB, however reading one page of documentation[^] suggests you might want RefCursor.

hi luc,thanks for reply . let me try it using refCursor

I'm using the code below to temporarily set a window to top most foreground. How can I return it to the standard function of being in the foreground depending on the last time it was touched by the mouse? I can't seem to figure out which uint32 to use to achieve what I'd like?
private static readonly IntPtr HWND_TOPMOST = new IntPtr(-1);
private static readonly IntPtr HWND_NOTOPMOST = new IntPtr(-2);
private const UInt32 SWP_NOSIZE = 0x0001;
private const UInt32 SWP_NOMOVE = 0x0002;
private const UInt32 SWP_NOZORDER = 0x0004;
private const UInt32 SWP_NOREDRAW = 0x0008;
private const UInt32 SWP_NOACTIVATE = 0x0010;
private const UInt32 SWP_DRAWFRAME = 0x0020;
private const UInt32 SWP_FRAMECHANGED = 0x0020;
private const UInt32 SWP_SHOWWINDOW = 0x0040;
private const UInt32 SWP_HIDEWINDOW = 0x0080;
private const UInt32 SWP_NOCOPYBITS = 0x0100;
private const UInt32 SWP_NOOWNERZORDER = 0x0200;
private const UInt32 SWP_NOREPOSITION = 0x0200;
private const UInt32 SWP_NOSENDCHANGING = 0x0400;
private const UInt32 SWP_DEFERERASE = 0x2000;
private const UInt32 SWP_ASYNCWINDOWPOS = 0x4000;
private const UInt32 TOPMOST_FLAGS = SWP_NOMOVE | SWP_NOSIZE;
private const UInt32 NOTOPMOST_FLAGS = SWP_SHOWWINDOW;
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, uint uFlags);
SetWindowPos(this.Handle, HWND_TOPMOST, 0, 0, 0, 0, TOPMOST_FLAGS);
Thanks!

Hi,
I've tried multiple variations of what I think is correct and it is not working. Here is an example of what I thought was correct
SetWindowPos(this.Handle, HWND_TOP, 120, 240, 200, 400, 0);
Can you tell me what I'm doing wrong? When using the above code, the window is still at the top most, even when I click on another window to bring it to the foreground.
|
|
|
|
|
It all seems to work for me. Can you provide some more details of exactly what you are doing, and exactly what results you get?
|
|
|
|
|
Sure, I am having the program go to top most after a button click and then selecting coordinates on the screen with the mouse and clicking another button to send keys to those coordinates and then after it is done I'd like for it to go back to standard Z order, but it is staying at top most.
|
|
|
|
|
Fine, but we cannot guess what your code is actually doing.
|
|
|
|
|
Here is the button click function, would you like me to copy/paste the entire code?
private void btnSelectTypingBox_Click(object sender, EventArgs e)
{
try
{
if (tempBlocker == false)
{
if (btnSelectTypingBox.Text == "Select Box")
{
btnSelectTypingBox.Text = "Waiting";
tempBlocker = false;
SetWindowPos(this.Handle, HWND_TOPMOST, 0, 0, 0, 0, TOPMOST_FLAGS);
}
else if (btnSelectTypingBox.Text == "Waiting")
{
btnSelectTypingBox.Text = "Select Box";
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message + " | " + ex.Source + " | " + ex.InnerException + " | " + ex.StackTrace);
}
}
|
|
|
|
|
How about
SetWindowPos(this.Handle, HWND_NOTOPMOST, 0, 0, 0, 0, SWP_NOSIZE | SWP_NOMOVE| SWP_NOZORDER); ?
some extra SWP values might be required...
|

Hi Luc,
Here is what I tried, but it did not work for me
private void btnTest_Click(object sender, EventArgs e)
{
SetWindowPos(this.Handle, HWND_NOTOPMOST, 0, 0, 0, 0, SWP_NOSIZE | SWP_NOMOVE | SWP_NOZORDER);
}
And here is my pininvoke code
private static readonly IntPtr HWND_TOPMOST = new IntPtr(-1);
private static readonly IntPtr HWND_NOTOPMOST = new IntPtr(-2);
private static readonly IntPtr HWND_TOP = new IntPtr(0);
private const UInt32 SWP_NOSIZE = 0x0001;
private const UInt32 SWP_NOMOVE = 0x0002;
private const UInt32 SWP_NOZORDER = 0x0004;
private const UInt32 SWP_NOREDRAW = 0x0008;
private const UInt32 SWP_NOACTIVATE = 0x0010;
private const UInt32 SWP_DRAWFRAME = 0x0020;
private const UInt32 SWP_FRAMECHANGED = 0x0020;
private const UInt32 SWP_SHOWWINDOW = 0x0040;
private const UInt32 SWP_HIDEWINDOW = 0x0080;
private const UInt32 SWP_NOCOPYBITS = 0x0100;
private const UInt32 SWP_NOOWNERZORDER = 0x0200;
private const UInt32 SWP_NOREPOSITION = 0x0200;
private const UInt32 SWP_NOSENDCHANGING = 0x0400;
private const UInt32 SWP_DEFERERASE = 0x2000;
private const UInt32 SWP_ASYNCWINDOWPOS = 0x4000;
private const UInt32 TOPMOST_FLAGS = SWP_NOMOVE | SWP_NOSIZE;
private const UInt32 NOTOPMOST_FLAGS = SWP_SHOWWINDOW;
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, uint uFlags);

Hi,
two things:
1. "did not work for me" isn't helpful; what did it do? and what did it not do that you were hoping to get? please be precise.
2. why is this in a new Click handler, I was expecting this to go in the else block, as counterpart to your SetWindowPos(this.Handle, HWND_TOPMOST...).
