Ok. Sorry it's under the new tab. My mistake.

Hi Experts,

I have a requirement to access a connected printer device through their embedded web server.
The device had an option to secure its details using username and password.
Once it is set, we can only communicate through "https" to that device.
Also there is windows credentials popup will come from UWP app once we initiate communication through https and wait for the user to enter the correct username and password as in web server.

My requirement is we need to pass those credentials as authorization header for a POST request to that device.

eg:-
Authorization: Basic YWRtaW46MTIzNDU2Nzg5

How to access those Windows credentials in UWP app. Without this authorization token, i am getting HTTP:401 unauthorized error for the POST request.

Please guide me to resolve this issue.

What I have tried:

I tried hard coding the username and password entered in the web server.

var username = usrName;
var password = pwd;
var base64String = Convert.ToBase64String(Encoding.ASCII.GetBytes($"{username}:{password}"));
_httpClient.AuthorizationHeader = new KeyValuePair("Basic", base64String);

then in this case the POST request is successful.

Also tried the same in a separate test application. In that case after entering the credentials in the windows credentials popup the same POST request is again sending automatically with those credentials as Basic auth token.

Hi Experts, I have a problem. I need to do several cleanup jobs , when the system log off. I tried it by using WM_QUERYENDSESSION on Activex Control class. But it is not working. Please help me. Thanks, Spk.

Hi John, You can use DrawImage() to rescale images... Regards, Spk521

Hi John, You can solve your problem by implementing double buffering concept...ie you can do all the drawings in a bitmap and once your drawings are over just bitblt it in to your client DC.. Regards, spk521

thank you very much experts...

Thanks laj its working....

ys.. i need to convert hex to its corresponding ascii value...

Hi All, Please let me know some hints to convert a hex value to a string.. Regards, Spk521

Please include code containing the drawing part...

call UpdateData(FALSE);

Thats based upon your requirement... if you need to convert 80% of the bitmap alpha values use this sample one... ColorMatrix colorMatrix = {1.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f, 1.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f, 1.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f, 0.8f, 0.0f, 0.0f, 0.0f, 0.0f, 0.0f, 1.0f}; ImageAttributes imageAtt; imageAtt.SetColorMatrix(&colorMatrix, ColorMatrixFlagsDefault, ColorAdjustTypeBitmap); Regards, Spk

You have to specify Colormatrix and load it via ImageAttributes' SetColorMatrix() before using DrawImage() Regards, Spk

Did you set the style of ComboBox as CBS_OWNERDRAWVARIABLE?

Hi Experts, Please let me know if any method is there to convert .json file to .po/.pot file in python script.. I have used Gettext library to parse po files and convert it to .json. But can't found any one to parse po files... Regards, Spk

You restrict your window's size by handling the WM_GETMINMAXINFO message. LRESULT OnGetMinMaxInfo ( WPARAM wParam, LPARAM lParam ) { MINMAXINFO* pmmi = (MINMAXINFO*) lParam; pmmi->ptMinTrackSize.x = 100; pmmi->ptMinTrackSize.y = 150; pmmi->ptMaxTrackSize.x = 600; pmmi->ptMaxTrackSize.y = 400; return 0; }
