postgresql - libpq: How to get the error code after a failed PGconn connection -

-

निम्न कोड को देखते हुए। 

  Pgconn * const conn = PQconnectdbParams (कीवर्ड, मान, असत्य); अगर (! Conn || PQstatus (conn)! = CONNECTION_OK) {/ * त्रुटि कोड? * /}

एक असफल कनेक्शन के मामले में त्रुटि कोड को गलत पासवर्ड और सर्वर के बीच अंतर करने में सक्षम होने का एक तरीका है।

(मुझे पता है कि मुझे त्रुटि संदेश मिल सकता है, लेकिन मैं इसके कारण के अनुसार त्रुटि के कारण प्रतिक्रिया करना चाहता हूं)।

धन्यवाद।

कुछ और शोध करने और पोस्टग्रेस डेवलपर्स पूछने के बाद ऐसा लगता है कि वर्तमान में PQconnectdbParam () से त्रुटि कोड प्राप्त करना संभव नहीं है।

यह स्वयं लिपिपीक की कमी है, जो आंतरिक रूप से (जैसे अज्ञात होस्टनाम) का पता लगाता है, त्रुटियों के लिए एसकेलस्टेट त्रुटि कोड को सौंपने का प्रयास नहीं करता है।

यह पोस्टग्रेर्स देव TODO सूची लेकिन यह प्राथमिकता नहीं है।

TL; DR: यदि आप लिपपीक का उपयोग करने जा रहे हैं, तो पाठ त्रुटि संदेश के साथ जीना सीखें (जो भी भाषा में स्थानीयकृत है)।

I am working on the terminal on a shell script after this tutorial SQLAlchemy tutorial.

uislider - In a MATLAB GUI, how does one implement a continuously varying slider from a GUIDE created .m file? -

-
I am trying to create a GUI with a plot and a slider. The slider should be described as continuously and output. I have a problem with this explanation that the uicontrol object is programmatically created, on the contrary, I want to know that in the last three instances, to complete the same thing done according to the program What can be added to a GUI file that is created. The code is down, and I have marked the (wrong) code that is provided by some of the above examples. Thanks a lot for any help! This slider function sets P1_slider_Callback (hObject, eventdata, handle) (handle, dragon, 'string', num2str (get (hObject, 'value'), 3)) PlottheData_Callback ( HOBject, EventData, Handle)% "PlotHeadata" is a button that creates the data slider based on the value of P1_slider%, and I think that here "p1_slider_CreateFcn" (hObject, eventdata, handle) needs to be assembled (HOBJECT, 'BackgroundRoller'), (0, 'Default UITTACKBACK MANDROLLE...

python - Openpyxl 1.8.5: Reading the result of a formula typed in a cell using openpyxl -

-
I'm printing some formula in one of the Excel sheets: wsOld.cell (Line = 1, column = 1) .value = "= B3 = B4" But I can not do this to introduce some other logic, as such: if ((wsOld.cell (line = 1, column = 1) .value) = 'true'): # Copy the second line of the second line Even when I'm trying to print results in the command line, I touch the formula Mapt hereby: > gt; & Gt; Print (wsOld.cell (line = 1, column = 1)) & gt; & Gt; & Gt; = B3 = B4 How can I get the result of the form in the cell and not the formula? OpenPaxL either supports the formula or value of the formula. You can choose whether to open a workbook by using the data_only flag. However, the OpenPixel will not calculate the result of a formula and will not. There is a pycel out of libraries like that which is to do.
