Hello everyone,
I am stuck with the following problem.
I have given text "We are living in a <upcase>yellow submarine</upcase>.", I have to change the text inside <upcase>....</upcase> to a uppercase letters so the result will be
"We are living in a YELLOW SUBMARINE."
Ill appreciate any help and suggestions how this can be done.
Thanks in advance!!
Regards

How do you know which part should be in upper case? If it's always the same text you might as well just output the right output..
|
|
|
|
|
My fault the text should be "We are living in a <upcase>yellow submarine</upcase>.
So I have to replace upcase ...... /upcase with the uppercase text.
Apologies.

Try this.
string openTag = "<upcase>", closeTag = "</upcase>";
string str = "We are living in a <upcase>yellow submarine</upcase>.";
int startIndex = str.IndexOf(openTag);
int endIndex = str.IndexOf(closeTag) + closeTag.Length;
string subStr = str.Substring(startIndex, (endIndex - startIndex));
subStr = subStr.Replace(openTag, "");
subStr = subStr.Replace(closeTag, "");
subStr = subStr.ToUpper();
str = str.Remove(startIndex, (endIndex - startIndex));
str = str.Insert(startIndex, subStr);
hmmm pie

Thank you very much sir. It work like a charm  Now I have to see how to put this in a loop so I can check bigger strings with more tags.
One more time Thanks.
Greetings!

Funny you should mention that as I was going to edit thte above code for multiple tags.
private string upperCaseTags(string str, string openTag, string closeTag)
{
int startIndex;
while ((startIndex = str.IndexOf(openTag)) != -1)
{
int endIndex;
if ((endIndex = str.IndexOf(closeTag) + closeTag.Length) != -1)
{
string subStr = str.Substring(startIndex, (endIndex - startIndex));
subStr = subStr.Replace(openTag, "").Replace(closeTag, "").ToUpper();
str = str.Remove(startIndex, (endIndex - startIndex));
str = str.Insert(startIndex, subStr);
}
}
return str;
}
hmmm pie

One more time great job. You did it instead of me.
Thank you!

This can be improved by Regular Expression's Replace[^] method.

Oh didn't you notice, analogous to square roots, they recently introduced rectangular, circular, and diamond roots to determine the size of the corresponding shapes when given the area. Luc Pattyn[^]
|
|
|
|
|
Can they be nested?
If they can't, search the string for "<uppercase>" and "</uppercase>" and turn all substrings starting at index[2*i] ending at index[2*1+1] to uppercase (won't work correctly for invalid inputs but the idea is easily extended to using 2 index arrays)

sounds to me perfect case for Regular Expression. See Replace method of RegEx[^]

Regard with the strings may I ask one more question. I have to write a simple program to encode and decode string using encryption key.The encoding and decoding is performed by using XOR.
So Ive done encoding part
static void Main(string[] args)
{
string str= "19 5456 65";
string key = "546";
String encode = Encode(str, key);
String decode = Encode(encode, key);
Console.Write(str + "\n" + encode+"\n"+decode);
}
static string Encode(string str,string key)
{
char []keyChar = key.ToCharArray();
char[] strChar = str.ToCharArray(); int a = 0;
for (int i = 0; i < strChar.Length;i++ )
{
strChar[i] = (char)(strChar[i] | keyChar[a]);
a++;
if (a>keyChar.Length-1)
{
a = 0;
}
}
str = new string(strChar);
return str;
}
But when I try to decode those string its giving me the same encoded string.
Please if any one knows where I am wrong to help me.
Thanks!!!

How can I use DLL file in C#.NET ? I create dll in Borland C++ Compiler 5.5.1 and using C language.
Following code is not work.
My C Code;
-----------------------------------------------------
//hello.dll
#include <windows.h>
extern "C"
{
void __declspec (dllexport) function1()
{
MessageBox (NULL, "test message","test title",0);
}
}
BOOL WINAPI DllMain (HINSTANCE, DWORD, LPVOID)
{
return TRUE;
}
My C# Code;
-----------------------------------------------------
[DllImport("C:\hello.dll")]
public static extern void function1();
private void button1_Click(object sender, EventArgs e)
{
function1();
}
|
|
|
|
|
Does it give an exception (if so, what kind?) or does it just silently fail?
|
|
|
|
|
Ok, I try this; But I get this error: Entry Point Not Found
C DLL CODE
-----------------------------------------------
#include <windows.h>
BOOL __stdcall DllMain(HINSTANCE hInst, DWORD dwReason, LPVOID lpReserved) {
return TRUE;
}
__declspec(dllexport) void __stdcall Message(char* p_szMessage) {
MessageBox(NULL, p_szMessage, "Message from DLL", MB_OK);
}
C# DLL CODE
-----------------------------------------------
[DllImport("filename.dll")]
static extern void Message(string msg);
private void button1_Click(object sender, EventArgs e)
{
Message("Hello world");
}
|
|
|
|
|
Just put hello.dll in C:\WINDOWS\system32
and replace [DllImport("C:\hello.dll")] with [DllImport("hello.dll")]
IS that give any error or exception??

No, this article not related about my question.
I use Borland Compiler. Is it occour problem?

Article XMen has linked will tell you how to check if library that you have compiled exports symbol (function) you are referring to. So try that one, this can give you some hint.

fs.Close();
string query = "insert into uploadfile_t(Name,ContentType,Data) values (@Name,@ContentType,@Data)";
SqlCommand cmd = new SqlCommand(query);
cmd.Parameters.Add("@Name", SqlDbType.VarChar).Value = filename;

the following error will come

plz any one help me
any file will save and retrieve from db

wrong
string filepath = Server.MapPath(Request.ApplicationPath + "//");
string filename = Path.GetFileName(filepath);
FileStream fs = new FileStream(filepath, FileMode.Open, FileAccess.Read);
correct
string filepath = Server.MapPath(Request.ApplicationPath + "//");
string filename = Path.GetFileName(filepath);
FileStream fs = new FileStream(filepath <code>+ filename</code>, FileMode.Open, FileAccess.Read);
