我有一个隐藏的表单,这个加载一个子表单,2e表单也应该被隐藏

请注意:我最不习惯

ShowInTaskbar = false; //  should be hidden too

如果我使用(隐藏/可见),我最能够在表单之间进行通信,直到它的可见=真;

  this.SetParameterValueCallback += new SetParameterValueDelegate(ShowMain.SetParamValueCallbackFn);
        ShowMain.AddItemCallback = new AddItemDelegate(this.AddItemCallbackFn);
        //Showsub.Show();
        Showsub.Hide(); // not working

到目前为止我已经尝试过

this.Visible = false; // didnt work

 BeginInvoke(new MethodInvoker(delegate
            {
                Hide();
            })); // didnt work

base.SetVisibleCore(false); // didnt work, Im not able communicate between form

请回答问题, 否则不回答这个问题.

让我重新开始.我如何使用这个扩展内部Environment.GetSpecialFolder的类？

我不想要特别的根

root = Environment.GetFolderPath(Environment.SpecialFolder)

因为我想将此用于其他目的而不是.net.

例如,如何通过单击按钮调用(Favorites = 6)位置？

public class EnvironmentFolders
{

public enum SpecialFolder
{
    AdministrativeTools = 48,
    //{user name}\Start Menu\Programs\Administrative Tools 
    ApplicationData = 26,
    //{user name}\Application Data 
    CommonAdministrativeTools = 47,
    //All Users\Start Menu\Programs\Administrative Tools 
    CommonApplicationData = 35,
    //All Users\Application Data 
    CommonDesktopDirectory = 25,
    //All Users\Desktop 
    CommonDocuments = 46,
    //All Users\Documents 
    CommonFavorites = 31,
    CommonNonLocalizedStartup = 30,
    //non localized common startup 
    CommonPrograms = 23,
    //All Users\Programs 
    CommonStartMenu = 22,
    //All Users\Start Menu 
    CommonStartup = 24,
    //All …

如何显示平台目标.

如何获得一个整数的值x,表示为x!,它是数字1到x的乘积.

例: 5! 1x2x3x4x5 = 120.

int a , b = 1, c = 1, d = 1; 
printf("geheel getal x = ");
scanf("%d", &a);
printf("%d! = ", a);
for(b = 1; b <= a; b++)
{
     printf("%d x ", c);
     c++;
     d = d*a;
}

我试图找出使用下面的类锁定文件的进程.这里出了什么问题？

呼叫:

private void button1_Click(object sender, EventArgs e)
{
   Console.WriteLine(Win32Processes.GetProcessesLockingFile("locked_file.dll").ToString());
}

输出:

System.Collections.Generic.List`1 [的System.Diagnostics.Process]

使用此电话:

using System;
using System.Collections.Generic;
using System.Runtime.InteropServices;
using System.Diagnostics;
using System.Text;
using System.Threading;

namespace FileLockInfo {

    public class Win32Processes {

        /// <summary>
        /// Return a list of processes that hold on the given file.
        /// </summary>
        public static List<Process> GetProcessesLockingFile (string filePath) {
            var procs = new List<Process>();

            foreach (var process in Process.GetProcesses()) {
                var files = GetFilesLockedBy(process);
                if (files.Contains(filePath)) procs.Add(process);
            }
            return procs;

如何将包含1000行的单个文本文件拆分为多个较小的文件,例如每行300行？请记住,原始文件可能有多于或少于一千行.

file1.txt 300 lines -> rest
file2.txt 300 lines -> rest
file3.txt 300 lines -> rest
file4.txt 100 lines 

我试过以下但是没有用.

int counter = 0;
string line;

string lineoutput = (current_dir + "\\" + DateTime.Now.ToString("HHmmss") + ".txt");

System.IO.StreamReader inputfile;

inputfile = new System.IO.StreamReader(new_path);
while ((line = inputfile.ReadLine()) != null)
{
    System.IO.StreamWriter file = new System.IO.StreamWriter(current_dir + "\\" + DateTime.Now.ToString("HHmmss") + ".txt", true);

    string _replaceBackspace = ReplaceBackspace(read_file.ReadLine().ToLower());

    using (StreamWriter writer = new StreamWriter(lineoutput, true))
    {
        if (counter == 5000)
        {
            counter = …

我是ARM微控制器编程的初学者,但我确实有AVR和PIC微控制器的经验.

几天前我从ebay.com购买了(STM32 STM32F103VET6开发).我现在正在尝试编写这个板,但我不知道从哪里开始.我还收到了一张CD,其中包含一些数据表和一些文件(全部用中文).

谁能告诉我如何开始？或者有一些源样本......

我已经安装了Keil uVision4.我也有一个J-link调试器.

谢谢.

如何从进程ID获取FullName(路径)

例如,如果int id = 234

如何找到id的位置;

int Id = Convert.ToInt32(lvprocesslist.SelectedItems[0].SubItems[1].Text); 
string s = Process.GetProcessById(Id).MainModule.FileName; 
Console.WriteLine(Path.GetFullPath(s));

它不能在Windows PID下运行(记事本3704)无法正常工作

谢谢.

我正在尝试使用以下代码获取组合框项目数.它不会给出错误,也不会给出正确的计数.我想我必须将int转换为字符串,但是如何？

ComboBox1->ItemIndex = 1;
int count = ComboBox1->Items->Count;
Edit1->Text =  "Count: " + count;

我在这做错了什么？

呼叫

printf(filename(exename));

我的函数应该返回文件名

const char* filename(const string& str)
{
  const char* path;
  size_t found;
  found=str.find_last_of("/\\");
  path = (str.substr(found+1)).c_str();

  cout << str.substr(found+1); // ------------> is name ok 

  printf("\n\n");
  printf(path); // ------------> is name not ok random numbers
  printf("\n\n");
  return  path; // ------------> is not ok random numbers
}

如何使这个工作.javascript应该通过返回读取php值并显示它.

如何在Windows XP和7(.net2)上以大多数工作的百分比来显示总内存使用量

我尝试了以下解决方案没有成功(崩溃或冻结)

如何从c ++控制台应用程序执行.exe.我尝试了以下方法没有工作.

我想运行一个我创建了一段时间"Radio.exe"的应用程序.此应用程序在启动时读取xml文件,如果我手动运行此应用程序它工作正常,但如果通过控制台应用程序"Radio.exe"运行它无法找到xml文件？

{
    // cant find xml ?
    ShellExecuteA( NULL, NULL, path, NULL, NULL, SW_SHOW );

    // cant find xml ?
    ShellExecute(NULL, NULL, path, NULL, NULL, SW_SHOWNORMAL);
