inno setup - How to allow entering only alphanumeric chars in a TInputQueryWizardPage edit box? -

-

मुझे इनो सेटअप के TInputQueryWizardPage संपादित करें बॉक्स में केवल अल्फ़ान्यूमेरिक वर्णों को दर्ज करने की अनुमति है। मैं यह कैसे कर सकता हूँ?

एक अल्फ़ान्यूमेरिक वर्ण को पहचानने के लिए मैं विंडोज़ एपीआई फ़ंक्शन का उपयोग करेगा और असाइन किया गया इनपुट संपादन का OnKeyPress ईवेंट अगर मैं अल्फ़ान्यूमेरिक न हो तो मैं चाबी खाऊंगा: 

  [सेटअप] AppName = मेरा प्रोग्राम ऐप = संस्करण = 1.5 DefaultDirName = {pf} \ मेरा प्रोग्राम [कोड] #ifdef UNICODE #define AW "W" # # एफ़आई "ए" # एडीआईफ़ फ़ंक्शन IsCharAlphaNumeric (ch: चार): BOOL; बाहरी 'आईएसआईएचएचआरएएलएफ़ए न्यूमेरिकः {#AW}@user32.dll stdcall'; प्रक्रिया InputQueryEditKeyPress (प्रेषक: TObject; var कुंजी: चार); // प्रारंभ करें यदि वर्तमान में दबाए गए कुंजी अल्फ़ान्यूमेरिक नहीं है, तो उसे # 0 असाइन करें, यदि नहीं है तो IsCharAlphaNumeric (key) तो कुंजी: = # 0; समाप्त; प्रक्रिया प्रारंभिक विज़ार्ड; Var संपादन इंडेक्स: पूर्णांक; इनपुट पृष्ठ: TInputQueryWizardPage; आरंभ // इनपुट क्वेरी पृष्ठ बनाएं और एक संपादन आइटम इनपुट पेज जोड़ें: = CreateInputQuery पेज (wpWelcome, 'कैप्शन', 'विवरण', 'सबकैप्शन'); EditIndex: = इनपुटपृष्ठ। जोड़ें ('नाम:', गलत); // अपने कस्टम एक इनपुट पृष्ठ पर OnKeyPress ईवेंट विधि असाइन करें। संपादन [संपादित करें]। ओकेकुईप्रेस: ​​= @InputQueryEditKeyPress; समाप्त;

I'm trying to write some text for labels, shape titles etc. with my plots, but no benefit till now Has not happened . I do not want to print specific characters (I know how to use special characters), I want to write the entire text in Greek (maybe Unicode and text ' ?). , suggesting that I would like to mention that for some reason I can not get matplotlib to cooperate with Tex (using IPython notebook from Anaconda in Ubuntu 14.10) so that there really is an option Will not be the first. I tried loading the Arial font and it loads successfully but again I get square blocks instead of characters. I import matplotlib.font_manager FM PROP = FM Font Properties (fname = '/ usr / share / fonts / truetype / msttcorefonts / Arial.ttf') And then to display the string I u'Î? ? I ?? Î¿Ï ??

I have performed a linq query using Entityframework as below GroupMaster getGroup = Null; GetGroup = DataContext.Groups.FirstOrDefault (item = & gt; keyword.IndexOf (item.Keywords, StringComparison.OrdinalIgnoreCase)> = 0 & amp; amp; item.ISNAmd) I found an exception like the method when executing it LINQ units do not recognize the 'Inter 32 index of (system string, system. String compromise)' method, and This method can not be translated to Store expression. Includes () method is sensitive by default, then I need to convert to minimize.

You actually have four options Databases globally Change the colon of it can be done in many ways, a simple Google search should reveal to them. Change the mix of individual tables or columns. Use a stored procedure and specify the call statement on your query Perform...
