Why don't you use the aforementioned Powershell to run a scan/replace script and toss that into NETLOGON. Seems like that would be easier and more sensible, as it sounds like you're using organizational shares.

What is described here applies to both VS 2013 and VS 2015
Consider the case when one wants to make a sub-classed Control (using one of the standard MS provided WinForm Controls) as a separate Project: so that you can end-up with a nice .dll that you can then mount on Visual Studio's ToolBox for handy re-use.
The only relevant new Project Type available is Windows Forms Control Library which when selected gives you an initial Class definition like this:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace TestWinFormControlLibrary
{
public partial class UserControl1: UserControl
{
public UserControl1()
{
InitializeComponent();
}
}
}And you, foolish mortal, think you could easily rename the Project and change the Class code to something like this:
public partial class CustomTextBoxForWhatever: TextBox while still leaving the Project Output Type as it is (Class Library).
That won't compile because the call to 'AutoScaleMode in the Designer.cs file will fail because you have stumbled across the assumption VS makes that you are building a ContainerControl, while a sub-classed TextBox does not expose that Type.
Okay, so you take out the call to 'AutoScaleMode, and now your design view switches to no-view ... just the type of screen that you see when you a new Component to a WinForm project. But, you do have, indeed, a sub-classed Control to work with, compile, and then mount in the ToolBox as you wish.
Now, maybe (?) the designers of VS did not assume someone would want to start designing a custom Control by first defining the Control, and then adding another Project to the Solution of Type Windows Form in order to test the Control as it is developed.
If you start a Project of Type WinForms, you can then add a "Custom Control" to it, but then that Control will be embedded in a WinForms Project.
Do you see what I am getting at ? Have I missed something obvious ... again ?
Since you can stick a Control of whatever Type in the ContainerControl Prototype that a Project of Type WinForms Control Library builds-out for you ... is this a non-issue for most mortals ?
Why do I quibble as the executioner asks if I will have the blindfold: usually, if I am going to do this ... and I do ... do this ... I am going to override methods of the sub-classed Control for various reasons.
Could CodeProject not groan under the weight of one more article or tip-trick describing all ... this ?

Would not be the first time that I had to code constructors / initializers to account for the behavior of a designer when loading a control.
I live with a given designer's behavior, grateful that I'm aware of it, and override it at run-time (DLL call) when necessary.

You do realise that your question has nothing to do with C# don't you? When asking a question, it's appropriate to choose an appropriate forum; in your case, it's probably best to post here[^].

Hello,
I am looking that article:
Haar-feature Object Detection in C#[^]
I don't understand the classification part. So there are nodes with features, there are threshold on the stage and on the features. Where these thresholds comes?
Why on the tree there are a right or left part?
Of what I thought for the haar classification there are stages which are kernels to apply on the image and that all I don't understand why there is features and threshold.
Where could I get more information to understand these parts of the program?

If you have a question about the code in an article, post it in the forum at the bottom of the article. That way, the person who wrote the article will be notified that you've posted a question, and you won't be waiting for them to stumble across your post in a random forum.

As Richard has mentioned, you should always consider adding the comment to the article itself, it not only helps you but the future readers also.
Secondly, all of these things are covered in the theoretical teaching of these subjects. No author would likely start explaining these things in a single article, that would require a book to cover these algorithms, their descriptions and the methods used in their classification.
Ask the question at the end of the article to see if author has interest in explaining those parts, otherwise, consider getting yourself a good book or learn these online at Wikipedia or so.

I have wrote a simple library, in C# (visual studio 2010), to access ini files for different applications.
The code at the end.
When used in windows application wrote in C# (x86,x64) (visual studio 2010) function properly.
Now I want to use it in a new library (mylib)(x64) where all methods are declared static, running indicates no errors but does not report the values that should have read from ini file.
I tried to add to the new library (mylib)a standard class, where methods aren't static, thinking that the problem was linked to the declaration of the static method of "mylib.getinipara()" , but without results.
Where am I wrong;
Thanks
ps.: all library and programs are compliled using Visual Studio 2010 Ultimate.
This is the code of library for accessing ini files.
using System;
using System.Runtime.InteropServices;
using System.Text;
namespace FileINIAccess
{
public class IniAccess
{
public string path;
[DllImport("kernel32")] private static extern bool WritePrivateProfileSection(string lpAppName, string lpString, string lpFileName);
[DllImport("kernel32")] private static extern bool WritePrivateProfileString(string section, string key, string val, string filePath);
[DllImport("kernel32")] private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath);
[DllImport("kernel32")] private static extern int GetPrivateProfileSection (string lpAppName , StringBuilder lpReturnedString, int nSize , string lpFileName );
public void IniFile(string INIPath)
{
path=INIPath;
}
public Boolean WriteProfileString(string Section, string Key, string Value)
{
bool rs=WritePrivateProfileString(Section,Key,Value,path);
return rs;
}
public Boolean WritePrivatSection(string Section, string Value)
{
bool rs=WritePrivateProfileSection(Section,Value,path);
return rs;
}
public string GetProfileString(string Section, string Key, string DefValue)
{
StringBuilder temp=new StringBuilder(255);
int rs=GetPrivateProfileString(Section,Key,DefValue,temp,255,path);
if (rs>0)
{
return temp.ToString();
}
else
{
return DefValue.ToString();
}
}
public string GetProfileSection(string Section)
{
StringBuilder temp=new StringBuilder(255);
int rs = GetPrivateProfileSection(Section, temp, 255, path);
if (rs>0)
{
return temp.ToString();
}
else
{
return "";
}
}
}
}

Thanks for the reply,
I was on the indicated site, I modified the statements as reported, but the result is unchanged.
When I call "myfileini.GetProfileString(lpsection, lpkey, lpdefvalue, sb_retvalue, ui_lenretvalue, lpfile)" its return alwais the default value.
As if it does not find the file, yet it is in a specific directory, which I value by the method "myfileini.IniFile(lpPtah_File)"
Also the same .ini file is used by another application that uses the same library (FileIniAccess.IniAccess) to access and function properly,

The only way to find out what is happening is to use the debugger to step through the code.
|
|
|
|
|
Yes I have use debug step by step without error, all values are correct, but result its th same.
|
|
|
|
|
Something must be incorrect, but I have no way of guessing what it might be.
|
|
|
|
|
thanks for your time, other tests to do
bye

I have just tried your code on my system and it all works fine. You must have an invalid path or key somewhere in your code.
|
|
|
|
|
You're right I did not properly copied the .ini file, cut and paste gone bad.

Thanks again for the time you have dedicated to me

Hello,
I am planning to implement cue banner for Text boxes in .net. I want this cue text to work till user enters some text in the box, that is cue text should not disappear if user clicks on text box.
I got this example, but I have two problems with this.
using Microsoft.VisualBasic;
using System;
using System.Collections;
using System.Collections.Generic;
using System.Data;
using System.Diagnostics;
using System.Runtime.InteropServices;
public class Form1
{
private void Form1_Load(System.Object sender, System.EventArgs e)
{
CueBannerText.SetCueText(TextBox1, "Enter Name here");
}
public Form1()
{
Load += Form1_Load;
}
}
public static class CueBannerText
{
[DllImport("user32.dll", CharSet = CharSet.Auto)]
private static Int32 SendMessage(IntPtr hWnd, int msg, int wParam, [MarshalAs(UnmanagedType.LPWStr)]
string lParam)
{
}
[DllImport("user32", EntryPoint = "FindWindowExA", CharSet = CharSet.Ansi, SetLastError = true, ExactSpelling = true)]
private static extern IntPtr FindWindowEx(IntPtr hWnd1, IntPtr hWnd2, string lpsz1, string lpsz2);
private const int EM_SETCUEBANNER = 0x1501;
public static void SetCueText(Control cntrl, string text)
{
if (cntrl is ComboBox) {
IntPtr Edit_hWnd = FindWindowEx(cntrl.Handle, IntPtr.Zero, "Edit", null);
if (!(Edit_hWnd == IntPtr.Zero)) {
SendMessage(Edit_hWnd, EM_SETCUEBANNER, 1, text);
}
} else if (cntrl is TextBox) {
SendMessage(cntrl.Handle, EM_SETCUEBANNER, 1, text);
}
}
}
The above code is working good in Windows 7 and above. But in windows xp it is not working properly. In windows xp the cue text disappears when we click on text box.
Secondly I want to change the color of cuetext (currently it is in grey).
Is it possible to achieve my requirements using current code? Or Is there any other suitable methods for me?
|

|

Windows XP is now well out of support so you are on your own when trying to implement new features on it. This feature is only officially supported in Vista and beyond, as described at EM_SETCUEBANNER message (Windows)[^]. If you wish to change colours and other behaviours then you will need to write your own implementation, or subclass the control.

How to save HTML tag through C# ASP.Net Form?. when using Rich text box the browser display Error Message.
|
|
|

Member 12676814 wrote: when using Rich text box the browser display Error Message.
Unfortunately we cannot see your screen so have no idea what that message may be, or what you code is doing at the time.
|
|
|
|
|
There are some measures for preventing injection of malicious data - HTML tags and scripts are considered dangerous input. If you get a message like A potentially dangerous value was detected from the client and you are really sure you want to save that text, you may override the validation behavior of ASP.Net in the individual page by
<%@ Page Language="c#" ValidateRequest="false" ...
and in web.config
<httpRuntime requestValidationMode="2.0" />
|
|
|
|
|
If you're using .NET 4.5, it would be better to set the ValidateRequestMode property[^] on the specific control(s) which should be allowed to contain HTML.

Hi All!
I Have a Table1 Like This :
---------------------------
myID | myItem | IdCountry
2-----Japan------1
4-----US---------2
5-----UK---------1
7-----Canada----2
---------------------------
Now ,I fill combobox1 from with this Code :
string strQuery= @"SELECT myID,myItem FROM Table1 WHERE IdCountry=1";
SqlConnection cnnCbx = new SqlConnection(cnnClass.CnnString);
cnnCbx.Open();
SqlDataAdapter daCbx = new SqlDataAdapter(strCbxQueryItems, cnnCbx);
DataTable dtCbx = new DataTable();
daCbx.Fill(dtCbx);
cbxKindOfItems.ValueMember = "myID";
cbxKindOfItems.DisplayMember = "myItem";
cbxKindOfItems.DataSource = dtCbx.DefaultView;
Ho Can I get myID Value When I select an Item from Combobox ?
|
|
|
|
|
Try:
var myID = cbxKindOfItems.SelectedValue;
Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...
