Hi All,
I want to migrate my app from VB.net to C#. How feasible it is?
|
|
|
|
|
Very feasible, if you know both languages. If not, you can use various online translators to translate your code for you, though they are not perfect and will not translate your entire application all at once.
Other than that, it's entirely up to your skill set.

Try this[^].
It worked pretty well for me.
Cheers,

Hello
Can anybody explain to me why the following four bold lines of code yield different results to their counterparts on the line below? By my reckoning the results should be the same with the only difference being one set are printed to the console window and the other to a text file. The purple lines are definitely creating correct results because they are a product of help code for Microsoft Visual Studio .NET and the results look good. The red lines of code (my code) are definitely producing incorrect results and all four of the outputs are often identical. Am I doing some memory management incorrectly???
<br />
#include "stdafx.h"<br />
<br />
#using <mscorlib.dll><br />
#include <tchar.h><br />
#include <windows.h><br />
#include <stdio.h><br />
<br />
using namespace System;<br />
<br />
int _tmain(void)<br />
{<br />
_int64 ctr1 = 0, ctr2 = 0, freq = 0;<br />
int acc = 0, i = 0;<br />
FILE *storage;<br />
<br />
if(QueryPerformanceCounter((LARGE_INTEGER *)&ctr1) != 0)<br />
{<br />
storage = fopen("C:\\TestTimer.txt", "a");
for(i=0; i<100; i++) acc++;<br />
QueryPerformanceCounter((LARGE_INTEGER *)&ctr2);<br />
<br />
fprintf(storage, "Start Value %i\n", ctr1.ToString());<br />
Console::WriteLine("Start Value: {0}",ctr1.ToString());<br />
<br />
fprintf(storage, "End Value %i\n", ctr2.ToString());<br />
Console::WriteLine("End Value: {0}",ctr2.ToString());<br />
<br />
QueryPerformanceFrequency((LARGE_INTEGER *)&freq);<br />
<br />
fprintf(storage, "Frequency %i\n", freq.ToString());<br />
Console::WriteLine(S"QueryPerformanceCounter minimum resolution: 1/{0} seconds.",freq.ToString());<br />
<br />
fprintf(storage, "Time %i\n", ((ctr2-ctr1) * 1.0 / freq).ToString()); <br />
Console::WriteLine("100 Increment time: {0} seconds.",((ctr2-ctr1) * 1.0 / freq).ToString());<br />
<br />
fclose(storage);<br />
} <br />
return 0;<br />
}

ToString() returns String objects(overloaded to char* in this case), but when you use %i with fprintf, it expects an integer. What you want to do is change the %i's in fprintf to %s. fprintf(storage, "Start Value %i\n", ctr1.ToString()); should be fprintf(storage, "Start Value %s\n", ctr1.ToString());.
Helps to have another pair of eyes sometimes eh? :P
As an alternative, you might consider using StreamWriter to avoid that sorta mistake. Here's the same thing with StreamWriter:
<br />
#include "stdafx.h"<br />
<br />
<br />
#include <windows.h><br />
#include <mmsystem.h><br />
<br />
using namespace System;<br />
using namespace System::IO;<br />
<br />
int _tmain(void)<br />
{<br />
_int64 ctr1 = 0, ctr2 = 0, freq = 0;<br />
int acc = 0, i = 0;<br />
StreamWriter* storage;<br />
<br />
if(QueryPerformanceCounter((LARGE_INTEGER *)&ctr1) != 0)<br />
{<br />
storage = new StreamWriter("C:\\TestTimer.txt", true); <br />
for(i=0; i<100; i++) acc++;<br />
QueryPerformanceCounter((LARGE_INTEGER *)&ctr2);<br />
<br />
storage->WriteLine("Start Value {0}", ctr1.ToString()); <br />
Console::WriteLine("Start Value: {0}",ctr1.ToString());<br />
<br />
storage->WriteLine("End Value {0}", ctr2.ToString());<br />
Console::WriteLine("End Value: {0}",ctr2.ToString());<br />
<br />
QueryPerformanceFrequency((LARGE_INTEGER *)&freq);<br />
<br />
storage->WriteLine("Frequency {0}", freq.ToString());<br />
Console::WriteLine(S"QueryPerformanceCounter minimum resolution: 1/{0} seconds.",freq.ToString());<br />
<br />
storage->WriteLine("Time {0}", ((ctr2-ctr1) * 1.0 / freq).ToString());<br />
Console::WriteLine("100 Increment time: {0} seconds.",((ctr2-ctr1) * 1.0 / freq).ToString());<br />
<br />
storage->Close();<br />
} <br />
return 0;<br />
} <br />

Hi all,
I'm writing a custom installer app and need to create shortcuts to go in the users startup directory.
I need to know how to create a shortcut file in code, i'm sure it can be done but for the life of me
I can't find anything telling me how.
Please help.
Kev

You must include a Reference to the Windows Scripting Library. In the Add Reference dialog, click the Com Tab and add the Windows Scripting Host Object Model.
use "using IWshRuntimeLibrary;"
make a shortcut a la
IWshShortcut shortCut = new IWshShortcut_ClassClass();
and start playing

Sounds good, I'll have a play.

I am trying to use the new AutoComplete in the the .net framework 2.0 beta and I can't seem to get it to work, I have read the help files on it (man this beta documentation is almost just an ndoc output  ) but I couldn't find any reason why it wouldn't work. I set a customCollection of words to match and set the auto complete collection to custom and set the auto complete mode to suggest and append but when I type in the text box nothing pops up. Anyone got any ideas?
|

|
|
Well I figured it out after a while, auto complete only works with single line edit boxes

Hi
I have doone a program such that using xpath , to read data's from xml and display it on a form.
now for ex:
XPathExpression Expr2;
Expr2 = oXPathNav.Compile("/tmp_day_stats//td_value");
XmlNamespaceManager oxmlNSManager = new XmlNamespaceManager(oXPathNav.NameTable);
oxmlNSManager.AddNamespace("tmp_day_stats", "http://myserver/myschemas/tmp_day_stats");
Expr2.SetContext(oxmlNSManager);
XPathNodeIterator iterator2 = oXPathNav.Select(Expr2);
while (iterator2.MoveNext())
{
this.textBox2.Text.ToString += this.textBox2.Text == "" ? iterator2.Current.Value: "\r\n"+ iterator2.Current.Value;
}
the above program what it does uis that read all the values of td_value from the xml file and display them in the textbox2.
ie, the output is as follows
900909.87887
980126.767
353553.543
776668.6466
now i have to format these numbers as follows
900909.87
980126.76
353553.54
776668.64
ie, after decimal i should have only 2 values to be shown.

Hi
Thanx for ur reply.
But what I need is that , it reads the fiedls values of "td_value" from a xml file and displays data ina textbox. so I dont know what are the values in the xml.
so whatever the values may be, I want to display them with 2 decimal places.
so can u give it in a general way.
ie, not by specifying values
as
string.Format("{0:f2}", somefloat)
the coding is in the above message . pls help me to do this.

Hello.
I want to get the full path of the file representing the current open Word document.
I was told that this could be done easily with VB by the function getObject, does anyone know of a way to do this in C#?
Thanks..
|
|
|
|

Are you saying you want to get the open document itself, or just the path? Keep in mind that Word can have many documents open. You need to get the Word.Application instance from the Running Object Table (ROT). To do that you pass "Word.Application" to System.Runtime.InteropServices.Marshal.GetActiveObject and cast to the ApplicationClass in the Word PIA (Primary Interop Assemblies; these are installed with a development feature of Office 2003 Professional and downloadable for Office XP from http://msdn.microsoft.com[^]. They can also be generated automatically.). Once you've done that you can easily get the active document:
using System;
using System.Runtime.InteropServices;
using Microsoft.Office.Interop.Word;
class ActiveDoc
{
const string WordProgId = "Word.Application";
static void Main()
{
ApplicationClass app = Marshal.GetActiveObject(WordProgId)
as ApplicationClass;
if (app != null)
{
try
{
DocumentClass doc = (DocumentClass)app.ActiveDocument;
if (doc != null)
Console.WriteLine(doc.Path);
}
catch (COMException)
{
Console.Error.WriteLine("No document is open.");
}
}
else
Console.Error.WriteLine("Word is not running.");
}
}
