Here is an other UDF for string handling :
Date handling
_StringDateConvert: convert a date from one format ("YMD", "MDY" or "DMY") to another.
_StringIsDate: checks if a date with a given format is valid
String management
_StringCount: count of occurrences that appear in a string
_StringFormatBytesSize: formatting a dimension expressed in bytes (bytes) in MB, TB, ...)
_StringIsEndingWith: check if a string end with some characters
_StringIsStartingWith: check if a string start with some characters
_StringJoinArray: concatenate elements of an array to rebuild a string
_StringPadLeft: filling a string with characters on the left
_StringPadRight: fill a string with characters on the right
_StringRemoveFrenchAccent: remove french accent
_StringRemoveChars: deleting characters from a string
_StringStrip: eliminate characters at the begin and/or at the end of a string
_StringTitleCaseFrench: capitalize the first letter of each word with elimination of french accents
_StringWSClean: simple replacement of "White Spaces", remove beginning and trailing spaces and multiple spaces removal
Any comments, suggestions for improvement or constructive criticism are welcome.
Below you will find the UDF and a demo program.

Hey All,
I'm trying to set the date using a variable.
Basically, I set the date into the input box, then I change the input box, say, I change the year.
Then I set what I typed into the input box into the Date Picker.
This is a demo code.
#include <ButtonConstants.au3> ;Start GUI includes #include <EditConstants.au3> #include <StaticConstants.au3> #include <WindowsConstants.au3> #include <DateTimeConstants.au3> #include <GUIConstantsEx.au3> #include <GuiDateTimePicker.au3> #Region ### START Koda GUI section ### Form= $Form1 = GUICreate("Form1", 615, 438, 192, 124) $Date1 = GUICtrlCreateDate("2019/02/02 23:16:26", 80, 64, 186, 21, $DTS_SHORTDATEFORMAT) $Input1 = GUICtrlCreateInput("Input1", 80, 152, 185, 21) $Button1 = GUICtrlCreateButton("Set data", 176, 96, 75, 25) $Button2 = GUICtrlCreateButton("Read from input", 176, 200, 75, 25) GUISetState(@SW_SHOW) #EndRegion ### END Koda GUI section ### While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit Case $Button1 $Read = GUICtrlRead($Date1) GUICtrlSetData($Input1, $Read) MsgBox(-1, "", $Read) Case $Button2 $Read = GUICtrlRead($Input1) $New_date = StringReplace($Read, "/", "") $DAY = StringLeft($New_date, 2) $MON = StringMid($New_date, 4, 3) $YEAR = StringRight($New_date, 4) MsgBox(-1, "", $DAY & $MON & $YEAR) ;_GUICtrlDTP_SetFormat($hWndDate, "yyyy/MM/dd") $DateFormate = ($DAY & " " & $MON & " " & $YEAR) $DTM_SETFORMAT_ = 0x1032 ; $DTM_SETFORMATW GUICtrlSendMsg($Date1, $DateFormate, 0, "MM/dd/yyyy") EndSwitch WEnd

Hi, I thought I would never post a C/WinAPI related question in this forum ever, but here we are after a few years and me having learnt enough of C to write a basic console program
My issue is that I am trying to read my child process's stdout output but ReadFile never returns if the child exits or if it is killed... very strange , I have been trying to work my way around this. The options I can think of are:
Create a new thread and check for existance of the process constantly while reading Somehow make the pipe asynchronous (overlapped) so that I can read it in a non-blocking manner Fix ReadFile to return when the process ends Obviously I would prefer No. 3, I just want to make my program work. Here is my code if you guys want to take a look:
// No text highlighting for C/C++ but we have it for C#? Blasphemy! bool allium_start(struct TorInstance *instance, char *config, allium_pipe *output_pipes) { char *cmd; // Figure out the command string for execution if (config) { char *parameters = " -f -"; cmd = malloc(strlen(instance->tor_path) + strlen(parameters) + 1); if (!cmd) return false; strcpy(cmd, instance->tor_path); strcat(cmd, parameters); } else cmd = instance->tor_path; // Prepare startup info with appropriate information SecureZeroMemory(&instance->startup_info, sizeof instance->startup_info); instance->startup_info.dwFlags = STARTF_USESTDHANDLES; SECURITY_ATTRIBUTES pipe_secu_attribs = {sizeof(SECURITY_ATTRIBUTES), NULL, true}; HANDLE pipes[2]; if (output_pipes == NULL) { CreatePipe(&pipes[0], &pipes[1], &pipe_secu_attribs, 0); output_pipes = pipes; } instance->startup_info.hStdOutput = output_pipes[1]; instance->startup_info.hStdError = output_pipes[1]; instance->stdout_pipe = output_pipes[0]; // Stored for internal reference if (config) { // Reuse the pipes array to store standard input pipes CreatePipe(&pipes[0], &pipes[1], &pipe_secu_attribs, 0); instance->startup_info.hStdInput = pipes[0]; } // Create the process bool success = CreateProcessA( NULL, cmd, NULL, NULL, config ? true : false, 0, NULL, NULL, &instance->startup_info, SecureZeroMemory(&instance->process, sizeof instance->process) ); // Free command string if needed if (config) free(cmd); // Write config to Tor's standard input unsigned long bytes_written; if (success) { WriteFile(pipes[1], config, strlen(config), &bytes_written, NULL); // Work around for simulating Ctrl + Z which sends the substitution character (ASCII 26), // this is needed in order for Tor to detect EOT/EOF while reading the config WriteFile(pipes[1], &(char){26}, 1, &bytes_written, NULL); } CloseHandle(pipes[1]); // Return on failure if (!success) return false; } char *allium_read_stdout_line(struct TorInstance *instance) { char *buffer = instance->buffer.data; // Check for valid buffer and allocate if needed if (instance->buffer.size == 0 || !buffer) { buffer = instance->buffer.data = malloc(instance->buffer.size = 80 + 1); if (!buffer) return NULL; } // Process the input unsigned int read_len = 0; while (true) { // Read data unsigned long bytes_read; if (ReadFile(instance->stdout_pipe, buffer, 1, &bytes_read, NULL) == false || bytes_read == 0) return NULL; // Check if we have reached end of line if (buffer[0] == '\n') break; // Proceed to the next character ++buffer; ++read_len; // Resize buffer if it is full if (read_len == instance->buffer.size) { char *new_buffer = malloc(instance->buffer.size += 50); if (new_buffer) memcpy(new_buffer, instance->buffer.data, read_len); free(instance->buffer.data); if (!new_buffer) return NULL; instance->buffer.data = new_buffer; buffer = instance->buffer.data + read_len; } } // Terminate the new line with null character and return // Special handling for Windows, terminate at CR if present buffer[read_len >= 2 && buffer[-1] == '\r' ? -1 : 0] = '\0'; } The allium_start function creates the redirection pipes and the child process, the other allium_read_stdout_line function reads from the stdout pipe created by the first function, ReadFile in this function does not return when the child ends or gets killed.
I appriciate the help of the WinAPI gurus here, thanks in advance!

Hi,
Ones(some times twice) a month I get an e-mail with zip file, which has price updates from a supplier.
I have to upload the file to an FTP to get it processed.
When uploading the file, it will get "timestamped" with the time and date at which time the file was uploaded.
Normally this is fine, because I mostly upload the file the same day.
Sometimes it may take 1 or 2 days before I can upload the file.
For historical purpose, I would like to have the file timestamped with the original date.
I have tried using: _FTP_Command ( $hFTPSession, "MFCT YYYYMMDDHHMMSS path")
however this command does not work or change the timestamp as I expected.
Does anyone now a way how I can change the timestamp of a FTP-file?

Hi Guys,
I`m trying to record with my webcam in 5s intervalls and do some stuff between starting to record and stoping.
I took code from here: https://www.autoitscript.com/forum/topic/27925-webcam-example/
and took what looked relevant to me.
I use 3 different files:
Is called WMS.au3 and contains all the constants for the dll calls is called rec.au3 and does all necessary dll calls to start a webcam recording to a file Is called stopcam.exe and does the dll calls to stop recording into a file WMS.au3 :

Unfortunately this is not working as I thought it would be working.
Does someone see what I´m doing wrong?
It should record the webcam for about 10 seconds ( a little less) and save that to an .avi file.
It does not stop the recording , I have to stop the process manually...
Secondly, which confuses me more is that it creates the test.avi not in the location is specified in the script... its stored in the ScriptDir for whatever reason haha
I hope you can help me
