I would like to change "1964" to '1964'
I have tried all combination but no success
string rowString = "1964";
var myString = "1964";
var myStrin = Regex.Replace(myString, #"[\""]", "'", RegexOptions.IgnoreCase);
string y = rowString.Trim('"');
string yy = rowString.Replace("\"", String.Empty);
var yvc = rowString.Replace("\"", String.Empty);
rowString = rowString.Replace("\"", "'");
rowString.Trim('"', '\'', ' ');
rowString = rowString.Replace('"', ' ').Trim();
var somestring = rowString.Replace('"', ' ').Trim();
rowString = rowString.Replace("'", "''");
string strgs = rowString.Replace("'", "''");
string strgg = rowString.Replace("\"", "'");
string strgod = rowString.Replace("\"", "'");
string strgodd = rowString.Replace("\"", "").Replace("'", "");
just do var newString= "'" +myString + "'"

Say I have a string:
typed = "need replace this ap"
str = "hello I need to replace this asap"
so the end result I want would be this:
newStr = "hello I <bold>need</bold> to <bold>replace</bold> <bold>this</bold> as<bold>ap</bold>"
please don't mind the weird syntax.
I wonder if the order would matter, for example:
typed = "applicable app"
str = "the app is very applicable in many applications"
The end result I wish should be:
newStr = "the <bold>app</bold> is very <bold>applicable</bold> in many <bold>app</bold>lications"
right? is this possible?
Hey,If You can ignore the weird HTML syntax here,
Then I have wrote a solution for you,
Paste this code in dart pad here
removeDuplicates(var typed, var str) {
Map<String, String> m = new Map<String, String>();
var n = typed.length;
String ans = "";
//for storing the "typed" string (word by word) into a map "m" variable for later searching purpose
String temp = "";
int i = 0;
for (i = 0; i < n; i++) {
if (typed[i] == " ") {
m[temp] = temp;
temp = "";
} else {
temp = temp + typed[i];
}
}
//for storing the last word of the string "typed", coz loop will never find a space in last of the string
m[temp] = temp;
// map variable loop for search from map "m" in the "str" string, and matching if the word is present or not
var n2 = str.length;
String temp2 = "";
for (int j = 0; j < n2; j++) {
if (str[j] == " ") {
if (m.containsKey(temp2)) {
} else {
ans = ans + " " + temp2; //storing the "temp2" string into "ans" string, everytime it finds a space and if the string is not already present in the map "m"
}
temp2 = "";
} else {
temp2 = temp2 + str[j];
}
}
//for searching for the last word of the string "str" in map "m", coz loop will never find a space in last of the string,
if (m.containsKey(temp2)) {
} else {
ans = ans + " " + temp2;
}
return ans;
}
void main() {
String typed = "need replace this ap";
var str = "hello I need to replace this asap";
String answer = removeDuplicates(typed, str);
print(answer);
}
Here, I have made a method removeDuplicates() to simplify your work, You just have to pass those string in your method, and then it will return you the desired answer string by removing the duplicates, with a new string.
UPDATED CODE (TO SHOW HTML CODE):
removeDuplicates(var typed, var str) {
Map<String, String> m = new Map<String, String>();
var n = typed.length;
String ans = "";
//for storing the "typed" string (word by word) into a map "m" variable for later searching purpose
String temp = "";
int i = 0;
for (i = 0; i < n; i++) {
if (typed[i] == " ") {
m[temp] = temp;
temp = "";
} else {
temp = temp + typed[i];
}
}
//for storing the last word of the string "typed", coz loop will never find a space in last of the string
m[temp] = temp;
print(m);
// map variable loop for search from map "m" in the "str" string, and matching if the word is present or not
var n2 = str.length;
String temp2 = "";
for (int j = 0; j < n2; j++) {
if (str[j] == " ") {
if (m.containsKey(temp2)) {
temp2 = "<bold>" + temp2 + "</bold> ";
ans = ans + " " + temp2;
} else {
ans = ans +
" " +
temp2; //storing the "temp2" string into "ans" string, everytime it finds a space and if the string is not already present in the map "m"
}
temp2 = "";
} else {
temp2 = temp2 + str[j];
}
}
//for searching for the last word of the string "str" in map "m", coz loop will never find a space in last of the string,
if (m.containsKey(temp2)) {
temp2 = "<bold>" + temp2 + "</bold> ";
temp2 = "";
} else {
ans = ans + " " + temp2;
temp2 = "";
}
return ans;
}
void main() {
var typed = "applicable app";
var str = "the app is very applicable in many applications";
String answer = removeDuplicates(typed, str);
print(answer);
}
UPDATE 2 (ALL THANKS TO PSKINK FOR THE str.replaceAllMapped APPROACH)
replaceWithBoldIfExists(String typed, String str) {
var n = typed.length;
List<String> searchList = new List<String>();
String temp = "";
int i = 0;
for (i = 0; i < n; i++) {
if (typed[i] == " ") {
searchList.add(temp);
temp = "";
} else {
temp = temp + typed[i];
}
}
searchList.add(temp);
String pat = searchList.join('|');
final pattern = RegExp(pat);
final replaced =
str.replaceAllMapped(pattern, (m) => '<bold>${m.group(0)}</bold>');
return replaced;
}
void main() {
var typed = "need replace this ap";
var str = "hello I need to replace this asap";
print(replaceWithBoldIfExists(typed, str));
}
I'm currently trying retrieve list share available in my Azure account from salesforce. I'm trying to implement the example from below sample code:
https://learn.microsoft.com/en-us/rest/api/storageservices/list-shares#samplerequestandresponse
//private key: access key of my account
string storageKey =private key;
string storageName = 'accountName';
Datetime dt = Datetime.now();
string formattedDate = dt.formatGMT('EEE, dd MMM yyyy HH:mm:ss')+ ' GMT';
system.debug('formattedDate--'+formattedDate);
string CanonicalizedHeaders = 'x-ms-date:'+formattedDate+'\nx-ms-version:2016-05-31';
string CanonicalizedResource = '/' + storageName + '/\ncomp:list';
string StringToSign = 'GET\n\n\n\n\n\n\n\n\n\n\n\n' + CanonicalizedHeaders+'\n'+CanonicalizedResource;
system.debug('StringToSign--'+StringToSign);
Blob temp = EncodingUtil.base64Decode(storageKey);
Blob hmac = Crypto.generateMac('HmacSHA256',Blob.valueOf(StringToSign),temp ); //StringToSign
system.debug('oo-'+EncodingUtil.base64Encode(hmac));
HttpRequest req = new HttpRequest();
req.setMethod('GET');
//req.setHeader('content-type', 'application/xml');
req.setHeader('x-ms-version','2016-05-31' );
req.setHeader('x-ms-date', formattedDate);
string signature = EncodingUtil.base64Encode(hmac);
string authHeader = 'SharedKey salesforcestrongaccount'+':'+signature;
req.setHeader('Authorization',authHeader);
req.setEndpoint('https://<accountName>.file.core.windows.net/?comp=list');
Http http = new Http();
HTTPResponse res;
res = http.send(req);
System.debug(LoggingLevel.INFO, 'http.send result status: ' + res.getStatus());
Any help?
As Gaurav Mantri says, there are something wrong with your stringToSign. So you will get this error.
The right Shared Key Authentication is like this:
StringToSign = VERB + "\n" +
Content-Encoding + "\n" +
Content-Language + "\n" +
Content-Length + "\n" +
Content-MD5 + "\n" +
Content-Type + "\n" +
Date + "\n" +
If-Modified-Since + "\n" +
If-Match + "\n" +
If-None-Match + "\n" +
If-Unmodified-Since + "\n" +
Range + "\n" +
CanonicalizedHeaders +
CanonicalizedResource;
Here I create a test demo, you could refer to it.
List share:
string storageAccount = "storage account";
string accessKey = "accountkey";
string resourcePath = "?comp=list";
string uri = #"https://" + storageAccount + ".file.core.windows.net/" + resourcePath;
// Web request
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(uri);
request.Method = "GET";
request.Headers["x-ms-date"] = DateTime.UtcNow.ToString("R", System.Globalization.CultureInfo.InvariantCulture);
request.Headers["x-ms-version"] = "2015-02-21";
String stringToSign = "GET\n"

System.Security.Cryptography.HMACSHA256 hasher = new System.Security.Cryptography.HMACSHA256(Convert.FromBase64String(accessKey));
string strAuthorization = "SharedKey " + storageAccount + ":" + System.Convert.ToBase64String(hasher.ComputeHash(System.Text.Encoding.UTF8.GetBytes(stringToSign)));
request.Headers["Authorization"] = strAuthorization;
Task<WebResponse> response = request.GetResponseAsync();
HttpWebResponse responseresult = (HttpWebResponse)response.Result;
using (System.IO.StreamReader r = new System.IO.StreamReader(responseresult.GetResponseStream()))
{
string jsonData = r.ReadToEnd();

I've set up an SQL database and used 'Date' as my column header which obviously has its own format as opposed to integer or char etc. However when I put in a date such as 2/11/2016 it gives me the error message - 'DATE' cannot hold values of type 'INTEGER'. Does anyone know what code I should be using? Here's my jsp below. All goes into DB when I remove all reference to date.

You need to remove the
if (dr.Read() == true)
because it is immediately followed by a
while (dr.Read())
Each of these will read a record and the first one will skip the first row of the file
