Howto Post a file to a webserver ??? 10-Sep-01 4:56 10-Sep-01 4:56  Hi... I have a webserver on which I use a Perl Script to do WebBased file upload. The script is called upload.pl. If I call the script http://server/cgi-bin/upload.pl is shows 3 EditBoxes... 1. UID 2. Password 3. Path of the file to upload !!! I want to call the script with a Dialog-Based Application (Visual C++)... first I tried to simply call the upload-script by http://server/cgi-bin/upload.pl?uid=xxx&pwd=yyy&file=C:\autoexec.bat&submit=Upload But this won't work... I sniffed on my Ethernet Card to look what my PC sends to the WebServer !!! Then I see that the client sends not the FileName c:\autoexec.bat but the DATA of c:\autoexec.bat to the webserver !!! The upload Script calls a How could I send the File to the WebServer with Visual C++ (binaries,text) ??? Have anyone an idea ??? or knows sources on the www where I will find a solution ???

See the HTML standard to see how the response should be formatted. Re: Howto Post a file to a webserver ??? Agent_White10-Sep-01 23:09 Agent_White 10-Sep-01 23:09  Thanx for your answer... the URL was is a good place to look at !!! But there are still problems left... because I have no experience with wininet at all !!! In my opinion... to solve the problem... I must read the Data of the file in a buffer (no problem) and then send it with the HTTP request (big problem) !!! Maybe someone knows a source which posts a file to a server ??? cu Agent_White combining two tiff images sukesh10-Sep-01 4:12 sukesh 10-Sep-01 4:12  May I know the algorithm or the procedure to combine two different TIFF Images into one single TIFF Image?? ALso I'm specific in combining the two pages of single TIFF image into one single Page...so, i would appreciate if someone could reply me thanks sukesh sabbani Re: combining two tiff images Christian Graus10-Sep-01 12:47 Christian Graus 10-Sep-01 12:47  From memory GDI+ will read and write TIFF. Then it's a case of using BitmapData to step through both bitmaps and combine the data as you see fit.

FreeImage has a MergeImages function (or something like that). how can sure other thread receive my data in a busy thread. zecodela10-Sep-01 3:17 zecodela 10-Sep-01 3:17  hi all, i am in a situation that there is a higher priority thread for wait event from a transmission bus. the bus will receive large amount of data in short period and go back to silent. it will miss data if i put too much processing code in that thread. so, i put the processing code in a new thread. so, could anyone tell me any method to pass data to other thread savely ( make sure all data is received by the processing thread. if i use filemapping or global variable, i can't sure the processing thread can received b4 new data is received from receiving thread but i can't wait for processing thread to finish its work ) anyone can help? thanks, jim Re: how can sure other thread receive my data in a busy thread.

Manikandan10-Sep-01 1:59 Manikandan 10-Sep-01 1:59  How to find the end points of all lines (hatch) filling a polygon?. The lines are inclined with an angle and have a constant spacing between them. Re: Hatching... Joaquín M López Muñoz10-Sep-01 8:46 Joaquín M López Muñoz 10-Sep-01 8:46  Rotate and scale your polygon so that the hatching is transformed to a horizontal hatching with spacing 1. Then, for each segment of your polygon, points within it with integer y are hatching end points. Transform them back and you're done. For a hatching angle θ and a spacing s, the resulting transformation is: x' = ( x cos θ + y sin θ) / s, y' = (-x sin θ + y cos θ) / s. And the reverse transformation is: x = ( x' cos θ - y' sin θ) · s, y = ( x' sin θ + y' cos θ) · s. Good luck.

Re: combobox::getitemtext Ivan A Eryshov10-Sep-01 3:05 Ivan A Eryshov 10-Sep-01 3:05  You must use GetLBText method: CComboBox combo; CString str; combo.GetLBText( combo.GetCurSel(), str ); in "str" you have items data. Re: combobox::getitemtext 10-Sep-01 3:11 10-Sep-01 3:11  to get proper item's text depends on initial ownerdrawfixed flag is it normal?

CRichEditCtrl: message handling 10-Sep-01 1:19 10-Sep-01 1:19  I have a CRichEditCtrl in a CView class. I need to know when the control gets the focus and I don't know how to do it. This is what I've done so far: //On MyView.h afx_msg void OnStupidCtrlGetFocus(NMHDR* pNMHDR, LRESULT* pResult); //On MyView.cpp ON_NOTIFY(NM_SETFOCUS, ID_STUPIDRICHEDITCTRL, OnStupidCtrlGetFocus) void CMyView::OnStupidCtrlGetFocus(NMHDR* pNMHDR, LRESULT* pResult) { //Do some work } But it doesn't work !!! what am I doing wrong ???? Thanks in advance.. How do I ensure a unique ID for my dynamically created button? Tommy H D Svensson10-Sep-01 1:07 Tommy H D Svensson 10-Sep-01 1:07  Hi all, I create a button dynamically but as it is now, I create the button ID myself like this cause in this case I can't use the editor to create it: #define ID_MY_BUTTON 33333 But how do I ensure a unique ID for this dynamically created button? /Tommy Re: How do I ensure a unique ID for my dynamically created button? XKent10-Sep-01 1:28 XKent 10-Sep-01 1:28  You can use _APS_NEXT_CONTROL_VALUE. Resource editor store here value which will be given to the next created control - so values above this not used. Acid will burn! Re: How do I ensure a unique ID for my dynamically created button? 10-Sep-01 1:53 10-Sep-01 1:53  i afraid it is good for first control but not for system dialog or any ole ctrls there he must search all parent's sub-windows or similar (?) t! Re: How do I ensure a unique ID for my dynamically created button? Tommy H D Svensson10-Sep-01 2:33 Tommy H D Svensson 10-Sep-01 2:33  Ok, so you mean that I can do like this: m_pBtn->Create(_T("Button"), WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON, CRect(0,0,19,14), this, _APS_NEXT_CONTROL_VALUE); Because m_pBtn is not associated with a resource editor created control, it's createed from scratch and subclassed dynamically. /T Re: How do I ensure a unique ID for my dynamically created button? XKent10-Sep-01 8:24 XKent 10-Sep-01 8:24  This true only for first item, then you must increase value youreself: m_pBtn->Create(_T("Button1"), WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON, CRect(0,0,19,14), this, _APS_NEXT_CONTROL_VALUE+1); m_pBtn->Create(_T("Button2"), WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON, CRect(0,0,19,14), this, _APS_NEXT_CONTROL_VALUE+2); You keeping unique values. You need do this only in one scope, so when you create item with different's parent you can use same ID's: m_pBtn->Create(_T("Button1"), WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON, CRect(0,0,19,14), pWnd1, _APS_NEXT_CONTROL_VALUE); m_pBtn->Create(_T("Button2"), WS_CHILD | WS_VISIBLE | BS_PUSHBUTTON, CRect(0,0,19,14), pWnd2, _APS_NEXT_CONTROL_VALUE); There is no problem, couse different parent's: pWnd1, pWnd2.
