Guys i need help with coding...
The goal is to... "take screen shot" (done) and "send it to ftp server" (done) then "copy file link to windows clipboard" (problem) This is the code i use, for the script: //create a filename based on "year-month-day_hour minute symbol" string filename = TimeYear(TimeCurrent())+"-"+TimeMonth(TimeCurrent())+"-"+TimeDay(TimeCurrent())+"_"+TimeHour(TimeCurrent())+""+TimeMinute(TimeCurrent())+"-"+Symbol(); //take screenshot of current chart if(!WindowScreenShot(filename+".gif",1280,600,-1,-1,-1)) GetLastError(); //send "year-month-day_hour minute symbol.gif" to specified ftp server else if(!SendFTP(filename+".gif","/Journal/Current Month/")) GetLastError(); /*when send is complete and no error, copy the entire link to clipboard. example: "http://www.someftpsite.com/someftpfolder/year-month-day_hour minute symbol.gif" is copied into the clipboard so we can paste that link text anywhere we need. Please help me how to do this?? */:'( |

The easiest way is to call Alert() with the link. You can the select the text (in the upper gray area, not in the list) and copy it into the clipboard.
Directly copying into the clipboard is possible only with some direct calls into the windows API: http://www.codeproject.com/KB/clipboard/archerclipboard1.aspx. These naked windows API calls always look like it is really great "fun" using them, especially from mql4 which has not the ability to define data structures :-/ |

ricx: I find it a little hard to believe that there isn't a better way to achieve whatever overall aim you have in mind, but the following MQL4 code will set the clipboard with a specified piece of text:The goal is to... "take screen shot" (done) and "send it to ftp server" (done) then "copy file link to windows clipboard" (problem) #import "kernel32.dll" int GlobalAlloc(int Flags, int Size); int GlobalLock(int hMem); int GlobalUnlock(int hMem); int GlobalFree(int hMem); int lstrcpyA(int ptrhMem, string Text); #import #import "user32.dll" int OpenClipboard(int hOwnerWindow); int EmptyClipboard(); int CloseClipboard(); int SetClipboardData(int Format, int hMem); #import #define GMEM_MOVEABLE 2 #define CF_TEXT 1 // Copies the specified text to the clipboard, returning true if successful bool CopyTextToClipboard(string Text) { bool bReturnvalue = false; // Try grabbing ownership of the clipboard if (OpenClipboard(0) != 0) { // Try emptying the clipboard if (EmptyClipboard() != 0) { // Try allocating a block of global memory to hold the text int lnString = StringLen(Text); int hMem = GlobalAlloc(GMEM_MOVEABLE, lnString + 1); if (hMem != 0) { // Try locking the memory, so that we can copy into it int ptrMem = GlobalLock(hMem); if (ptrMem != 0) { // Copy the string into the global memory lstrcpyA(ptrMem, Text); // Release ownership of the global memory (but don't discard it) GlobalUnlock(hMem); // Try setting the clipboard contents using the global memory if (SetClipboardData(CF_TEXT, hMem) != 0) { // Okay bReturnvalue = true; } else { // Failed to set the clipboard using the global memory GlobalFree(hMem); } } else { // Meemory allocated but not locked GlobalFree(hMem); } } else { // Failed to allocate memory to hold string } } else { // Failed to empty clipboard } // Always release the clipboard, even if the copy failed CloseClipboard(); } else { // Failed to open clipboard } return (bReturnvalue); } |

The following code copy text to clipboard. I need an opposite function. Could you help me copy text from clipboard? string CopyTextFromClipboard() { } The following code is by jjc. jjc 2010.03.25 16:06#import "kernel32.dll" int GlobalAlloc(int Flags, int Size); int GlobalLock(int hMem); int GlobalUnlock(int hMem); int GlobalFree(int hMem); int lstrcpyA(int ptrhMem, string Text); #import #import "user32.dll" int OpenClipboard(int hOwnerWindow); int EmptyClipboard(); int CloseClipboard(); int SetClipboardData(int Format, int hMem); #import #define GMEM_MOVEABLE 2 #define CF_TEXT 1 // Copies the specified text to the clipboard, returning true if successful bool CopyTextToClipboard(string Text) { bool bReturnvalue = false; // Try grabbing ownership of the clipboard if (OpenClipboard(0) != 0) { // Try emptying the clipboard if (EmptyClipboard() != 0) { // Try allocating a block of global memory to hold the text int lnString = StringLen(Text); int hMem = GlobalAlloc(GMEM_MOVEABLE, lnString + 1); if (hMem != 0) { // Try locking the memory, so that we can copy into it int ptrMem = GlobalLock(hMem); if (ptrMem != 0) { // Copy the string into the global memory lstrcpyA(ptrMem, Text); // Release ownership of the global memory (but don't discard it) GlobalUnlock(hMem); // Try setting the clipboard contents using the global memory if (SetClipboardData(CF_TEXT, hMem) != 0) { // Okay bReturnvalue = true; } else { // Failed to set the clipboard using the global memory GlobalFree(hMem); } } else { // Meemory allocated but not locked GlobalFree(hMem); } } else { // Failed to allocate memory to hold string } } else { // Failed to empty clipboard } // Always release the clipboard, even if the copy failed CloseClipboard(); } else { // Failed to open clipboard } return (bReturnvalue); } |
