That has nothing to do with the question, which clearly states that OP wants each process to complete before the next one starts.

Unless you are using numbers for complex mathematics, statisitics etc., you should not use floating point. Because of their inherent lack of precision they are best avoiided.

What exactly is the problem? As far as I can see you read the file into pBuffer but then do nothing with that data.

Richard MacCutchan 15-Apr-24 9:25am View

"Do you have any other suggestion?"
About what? It is far from clear what you are trying to do.

Richard MacCutchan 14-Apr-24 10:37am View

Maybe you need to rethink exactly what you are trying to achieve.

Richard MacCutchan 12-Apr-24 12:15pm View

Why are you doing the same reference twice, when you have already added it to the ComboBox? And what exactly is in the structure theApp.m_arrL?

Richard MacCutchan 12-Apr-24 11:45am View

The code you have shown suggests that you are adding the same string each time, which makes no sense. Please show the actual data and the code you are using.

Richard MacCutchan 12-Apr-24 10:23am View

Your question is impossible to answer as we have no idea what you are doing, or trying to do. Please add some proper details of the code you are using and what problems you have with it.

"I tried to use GetDlgIten but it isn't right"
And you think that somehow we can guess what your code is doing and fix it for you?

Richard MacCutchan 9-Apr-24 11:46am View

Why would you send a value as a string to an entity that expects an int?

Richard MacCutchan 9-Apr-24 3:37am View

It's Java not Javascript.

Richard MacCutchan 7-Apr-24 3:15am View

Without seeing your code it is impossible to guess.

Richard MacCutchan 5-Apr-24 12:32pm View

Then I am afraid you will have to use the debugger to find out what is happening.

Your list is all editors or IDEs. The question asks about alternative compilers.

Richard MacCutchan 5-Apr-24 7:21am View

Have you checked that your utf8_decode function returns a valid Unicode string?

Richard MacCutchan 5-Apr-24 4:34am View

Well that does not really tell us anything useful. Did you try calling GetLastError to see if that gives any reason for the failure? Have you checked that all parameters in your DOCINFO structure are valid?

Richard MacCutchan 5-Apr-24 3:56am View

What do you mean by "StartDoc is not succeeding"?

Richard MacCutchan 30-Mar-24 11:49am View

Do you have an actual question?

Richard MacCutchan 30-Mar-24 7:14am View

Using a cursor based display for such a game creates its own problems. You need to redraw every itme that the car moves through each time it passes along a road. This makes it quite difficult if the car is moving in any direction other thn left to right on the screen.

Richard MacCutchan 29-Mar-24 12:31pm View

Thank you again, happy to help you.

Part 2:
Displaying graphics is basically just the same as displaying text. But instead of using nLine and nChar, you need to calculate the offset from the top and left of the image. So passing the height and the width of the image to SetScrollRange will give you the values to use in deciding where to paint from.

As to your last request, I don't think my code will help as it is text based. Maybe if you add your WM_PAINT handler code to the question I can make some comments that would be more appropriate.

Richard MacCutchan 28-Mar-24 12:19pm View

Sorry, I guess my description was not clear. I mean that each time the paint event is called, it uses the scroll information to calculate whivch line of data, and which character in that line, to start with. So the first such characgter displays at point 0, 0. I always visualise this by taking a piece of paper with a square hole in it, and holding it over some printed text. So wherever you move the hole, you always see text starting in the top left corner.

Richard MacCutchan 28-Mar-24 12:14pm View

The type of variable pVpstr does not matter. The point is that it points to the lines of text that need to be displayed. I should have mentioned that this code is used to display text files with up, down, left and right scrolling enabled.

Richard MacCutchan 28-Mar-24 11:35am View

I will answer the first two questions as they are fairly easy:
1. I don't use ScrollWindow as in this sample i am displaying simple text. So each time WM_PAINT is called I repaint the entire Window starting at the point in the data that needs displaying. So if the page size is calculate as 20 lines and the scroll was caused by PAGE_DOWN I need to skip lines 1 to 20 and start by displaying line 21 of the text and beyond, always stopping when I hit the bottom of the display area.

2. The pointer pVpstr is a pointer to a vector that contains the lines of text to be displayed. Its size method returns the number of lines. So passing that value and the height of the display area to SetScrollRange returns the position in the data at which to start.

I need to think a bit more about the other queries.

Richard MacCutchan 28-Mar-24 11:00am View

Thanks Pete, your comments are always a boost to the ego.

Richard MacCutchan 28-Mar-24 10:22am View

See my solution below.

Richard MacCutchan 28-Mar-24 4:49am View

"So what am I doing wrong??"
Without seeing your code we cannot guess.

Richard MacCutchan 28-Mar-24 4:46am View

Your scrolling code should be happening in response to WM_PAINT, not in response to scroll messages.

Richard MacCutchan 27-Mar-24 7:28am View

All you need to do is just edit your question and show us the code that is not working.

Richard MacCutchan 27-Mar-24 7:12am View

No one can guess what your code is doing. Please provide proper details of the code and the data you are trying to process. And trying simple to 'convert' a string into a RichTextBox makes no sense. You need to populate the text box with data.

Richard MacCutchan 27-Mar-24 4:35am View

Sorry, no. As I said, you need to use the debugger to find out what the code is doing when it processes the file. Or maybe you need to study the documentation to check that you code is correct in the way it is processing the data.

Richard MacCutchan 26-Mar-24 4:30am View

Sorry, I cannot answer that. If the code works with a file that I created, then the issue must be with the content of your files. So you need to investigate further. One thing you could try to start with is to run the code in the Python debugger, so you can see the actiual values that are being found in the word file.

Richard MacCutchan 22-Mar-24 10:21am View

I just tried that code with a self created document and it correctly found the bold font.

Richard MacCutchan 22-Mar-24 10:09am View

Have you checked the actual content of the file that you are reading?

Richard MacCutchan 22-Mar-24 6:38am View

Please be patient, we are all volinteers here, and answer in our own time.

Richard MacCutchan 22-Mar-24 6:37am View

I just tried your code and the ids start at 1 and go up in sequence. You need to show what actually happens when you run it.

Richard MacCutchan 20-Mar-24 7:30am View

Thanks, I can't actually remember using CArray, but it is 20 years or so since I last used MFC.

Richard MacCutchan 20-Mar-24 7:10am View

Forwards or backwards should not matter, as he is not removing the array items. Or do I misunderstand something about CArray?

Richard MacCutchan 20-Mar-24 5:30am View

Your explanation does not make sense. If the item is NULL then the test will skip the delete. You need to do some more debugging to see exactly what is happening.

Richard MacCutchan 20-Mar-24 5:01am View

Well your question is not clear, so please explain exactly where it crashes, and what variable values are the cause.

You cannot load a text file into an image object, you need to read it into a character or string array.

Richard MacCutchan 10-Mar-24 8:55am View

What is the question?

Richard MacCutchan 8-Mar-24 12:47pm View

You do not need to call SetFocus before SetWindowText. But there is not enough information in your question to guess what is wrong.

Richard MacCutchan 8-Mar-24 3:53am View

See my updated Solution below.

Richard MacCutchan 7-Mar-24 11:14am View

Yes, I completely understand that. My point in posting this was to bring the issue to the OP's attention. If that is the sort of code that they later push into some large operational application, then all hell could break loose.

Richard MacCutchan 7-Mar-24 8:25am View

Thanks, it's not often that I see things before you.

Richard MacCutchan 7-Mar-24 4:16am View

Since you are calling perror even when no error occurred you are printing incorrect error messages. And most of those messages will be based on some random value in the error code variable.

Richard MacCutchan 6-Mar-24 13:33pm View

OK, then you need to put some logging messages into your code to get the information.

Richard MacCutchan 6-Mar-24 12:55pm View

Just because it compiles does not mean that the code does what you expect. Use the debugger to step through it so you can actually see where it is not updating values correctly.

Richard MacCutchan 6-Mar-24 11:49am View

stderr is an output stream managed by the shell. In normal circumstances it is printed on the terminal window. It is not clear what it has to do with the code you have shown above, or what you mean by, "retrieve".

But what you are referring to are not arrays, they are strings. You have a single array of QStringList items. And each list contains a number of strings.

You should not store dates as strings; use proper DateTime types.

Richard MacCutchan 22-Jan-24 4:24am View

You should not do that in WM_CREATE. As I have mentioned in a number of your other questions, you should do all screen displaying code in your WM_PAINT handler. And the size of the client window is returned in the PAINTSTRUCT structure after the call to BeginPaint, so you have all the relevant information to paint your client area. I am not sure why you need the dimensions of the scren or a bitmap of that size.

Richard MacCutchan 19-Jan-24 12:36pm View

I suspect that part of your problem is that you are manipulating device contexts in different parts of the code. Move all the code that deals with display issue into the WM_PAINT handler. That is how I have always done it, and never had any similar issues to this problem.

Richard MacCutchan 19-Jan-24 12:30pm View

Lots of simple errors which you can easily correct by reading the code. You are also missing a main method, so I doubt this will even compile.

Richard MacCutchan 5-Jan-24 11:30am View

Thanks, just what I thought. :)

Richard MacCutchan 5-Jan-24 10:34am View

It's quite possible that some Windows do not respond to such requests as thay are effectively system processes.

Richard MacCutchan 5-Jan-24 8:21am View

It was a serious point. But perhaps you did not bother reading it.

Richard MacCutchan 5-Jan-24 4:08am View

I am not an asp expert, but I think you may have mis-matched quotes in the OnClientClick attributes.

Richard MacCutchan 4-Jan-24 10:23am View

Which I already provided in my last reply.

Richard MacCutchan 4-Jan-24 10:12am View

Why have you changed the code to send CDRF_NEWFONT for every notification? Look at the example code that I have given the links for, and make sure you are sending the correct reponse at each paint stage.

Richard MacCutchan 4-Jan-24 9:16am View

See this article: Neat Stuff to Do in List Controls Using Custom Draw[^].

Richard MacCutchan 4-Jan-24 9:07am View

No, you return the status values in pResult, as you are already doing. But you need to ensure you return the correct notifications for the framework to process the control according to your settings, as I specified in my original post above.

Richard MacCutchan 4-Jan-24 6:31am View

Sorry, I don't understand what you mean.

Richard MacCutchan 4-Jan-24 5:17am View

If you get an exception, or any error, then it is important to provide the complete text, and also the line of code where it occurs. As it stands it is difficult to figure out what the above code is supposed to be doing. For example, what is the data that appears in the rtbIncoming box and where does it come from?

Richard MacCutchan 3-Jan-24 12:40pm View

Sorry, we cannot guess what the JSON data contains.

Richard MacCutchan 3-Jan-24 12:24pm View

Please show the JSON data that causes the problem.

Richard MacCutchan 3-Jan-24 6:40am View

This is not an answer (to a 13 year old question). If you have a problem then open a proper question yourself.

Richard MacCutchan 2-Jan-24 12:52pm View

Check which flags are set when the dialog returns TRUE. If PD_PAGENUMS or PD_SELECTION is set then the nFromPage and nToPage fields give you the values. If neither of those flags is set then you should print all pages. The documentation for PRINTDLGA (commdlg.h) - Win32 apps | Microsoft Learn[^] shows this.

Richard MacCutchan 31-Dec-23 3:31am View

Please stop writing as little as possible. Show us the actual code in its proper context, and the complete text of all error messages.

Richard MacCutchan 30-Dec-23 7:46am View

What is the error message, and where is line 35?

Richard MacCutchan 29-Dec-23 10:50am View

I assume you need to use GTK's own thread library: GLib – 2.0: Threads[^].

Richard MacCutchan 29-Dec-23 4:20am View

Unfortunately there is nothing in your question that gives us any clue as to what your problem is. Please use the Improve question link above, and add complete details of what is not working.

Richard MacCutchan 28-Dec-23 10:20am View

Well I still don't understand what the rules are for moving the numbers, or how many numbers are required (or limited to) in each column. For example, why is one column not just [ 50 ]?

Richard MacCutchan 28-Dec-23 9:16am View

The first thing I would do is to sort the numbers into ascending order. It is then a few simle calculations to find the lowest or highest set. But it is not exactly clear what actual result you are trying to find.

Richard MacCutchan 28-Dec-23 4:28am View

Please show the exact error messages in your question, and indicate where they occur.

Richard MacCutchan 28-Dec-23 4:26am View

Add an echo $sql; statement before the call to mysqli_query. That way you should be able to see what may be wrong.

Richard MacCutchan 27-Dec-23 6:45am View

Why are you storing Date values in text form, instead of proper Date types? And why do you not check the reurn value from the call t ExecuteNonQuery? TRy fixing those, and then run the code through the debugger to see exactly what is happening.

Richard MacCutchan 27-Dec-23 6:35am View

I am going by your statement, "but the background can not be exited". But since we have no idea what your code is doing it is impossible to offer any further suggestions. Please use the Improve question link above, and add complete details of what is not working.

Richard MacCutchan 27-Dec-23 3:50am View

You need to send the same message(s) to the background process.

Richard MacCutchan 24-Dec-23 15:18pm View

"As You can see ..."
Well maybe, but it would be so much more sensible, and useful, if you explained which part of the above code is the problem.

Richard MacCutchan 24-Dec-23 9:06am View

Have you checked the suggestion in Solution 2 below?

Richard MacCutchan 24-Dec-23 6:49am View

You should let the database library manage unique ids.

Richard MacCutchan 24-Dec-23 3:24am View

Maybe the filepath is wrong.

Richard MacCutchan 23-Dec-23 10:54am View

Which line in the above code causes the error?

Richard MacCutchan 23-Dec-23 7:52am View

"Can u plz correct this error"
No, because we do not have access to your system and have no idea where this library is stored.

Richard MacCutchan 23-Dec-23 7:50am View

That suggest thatg you are trying to convert a DBNull element to an integer or something similar. So examine your code to see where it is failing.

Richard MacCutchan 23-Dec-23 3:47am View

That is the C language ternary operator, which works this way:

expression ? value if true : value if false

// so the above statement can be broken down to:
if (nCmdId == GO_PAGE_1)
{
    // first ?
    hWndFrom = hMainPage;
}
else
{
    // first :
    if (nCmdId == GO_PAGE_2)
    {
        // second ?
        hWndFrom = hPage_1;
    }
    else
    {
        // second colon
        hWndFrom = hPage_2;
    }
}

I hope that makes sense.

Which version of assembler language is this, and which compiler are you using to build it?

Richard MacCutchan 21-Dec-23 8:11am View

I have deleted your duplicate of this question.

Richard MacCutchan 21-Dec-23 7:28am View

without seeing the code you use it is impossible for anyone here to guess what is happening. Please use the Improve question link above, and add complete details of what is not working.

Richard MacCutchan 20-Dec-23 10:21am View

So I assume that somewhere in all that code you get an error message. Please use the Improve question link above, and add proper details of where the error occurs.

Richard MacCutchan 20-Dec-23 8:48am View

I have no idea what that means. Please use the Improve question link above, and add the details to your question, so we can see what you are doing.

Richard MacCutchan 20-Dec-23 8:33am View

Well where are those results appearing? I see nothing in your code that would display the information you read from the scanner.
