[C#] a own Launcher in Work.

[Nikolee]

Since i started to Learn C# i got some problems to create a Launcher.

The Problem is:

I Can run the "nksp" on my Computer with "C:\...."

but how i can run it on other Computers?



Thats at the moment the only problem, hope you can help me ^^



string currentDir = Environment.CurrentDirectory;
Process.Start(currentDir@"\bin\nksp.exe");
System.Media.SoundPlayer sp = new System.Media.SoundPlayer(@"C:\Users\BOSS\Music\LC Musik\test.wav");



Look the Process.Start line, what i must edit there?^^

[HateMe]

thats simpel

 

//Starting the exe
if (File.Exists("Bin\\Nksp.exe"))
{
Process Nksp = new Process();
Nksp.StartInfo.FileName = "Bin\\Nksp.exe";
Nksp.StartInfo.Arguments = "4022";
Nksp.Start();
}

 

EP2 is "Nksp.StartInfo.Arguments = "4022";"

EP1 is "Nksp.StartInfo.Arguments = "6574";"

[Nikolee]

Which kontext i need to use?

 

German : öhm muss ich da noch was ergänzen mit using?

[HateMe]

put the code for example in a button

 

on

C#

add first
using System.Diagnostics;
....

// Starting the programm
private void start_Click(object sender, EventArgs e)
{
//Starting the exe
if (File.Exists("Bin\\Nksp.exe"))
{
Process Nksp = new Process();
Nksp.StartInfo.FileName = "Bin\\Nksp.exe";
Nksp.StartInfo.Arguments = "4022";
Nksp.Start();
this.close();
}
}

 

C++

void RunApplication(LPCTSTR FileName, LPCTSTR FileParam)
{
int ret = (int) ShellExecute(NULL, "open", FileName, FileParam, NULL, SW_SHOWNORMAL);

if (ret <= 32)
{
AnsiString msg;

switch(ret)
{
case ERROR_FILE_NOT_FOUND, SE_ERR_FNF :
msg = "File " + AnsiString(FileName) + " not found!";
break;

case ERROR_PATH_NOT_FOUND, SE_ERR_PNF :
msg = "Directory " + AnsiString(FileName) + " not found!";
break;

case ERROR_BAD_FORMAT :
msg = "The application is broken or cant run!";
break;

case SE_ERR_ACCESSDENIED, SE_ERR_SHARE :
msg = "Der Zugriff auf die Datei " + AnsiString(FileName) + " wurde vom Betriebssystem verweigert!";
break;

case SE_ERR_ASSOCINCOMPLETE, SE_ERR_NOASSOC :
msg = "Der angegebene Dateityp ist auf Ihrem Computer keiner Anwendung zugeordnet!";
break;

case 0, SE_ERR_OOM :
msg = "To run this Application u have not enough memory space!";
break;

default : msg = "Data " + AnsiString(FileName) + " could not opened!";
}

Application->MessageBox(msg.c_str(), "ERROR", MB_OK + MB_ICONERROR);
}
}

// Here is the button
void __fastcall TForm1::Button_StartClick(TObject *Sender)
{
AnsiString FileName = "Bin\\Nksp.exe";
AnsiString Parameter = "4022";
RunApplication(FileName.c_str(), Parameter.c_str());

// Close the Application
this->Close();
}

and works^^

[someone]

Add this:

using System.IO;

 

I dont know what start is supposed to mean.

 

@HateMe there are other things that make the code simpler in C++.

Try to use FormatMessage to get a string for the error message, instead of writing manually write your error. Or the alternative _com_error::ErrorMessage().

and take out the

start.Enabled = false;

I think the info on the prograssBar1_click should be in the updateButton_click, you can modify the progress bar by accessing the variable attached to your progress bar(in your case prograssBar1). Dont forget to set your progress bar maximun and minimun(min = 0, and max = 100).

 

in your updateButton_click, will be:

Download patch:

set progress bar at 50%(progressBar1.increment(50)

Apply patch

setprogress bar at 100%(progressBar1.increment(50)

 

To check if you got 100% you could just use:

if(progressBar1.value >= progressBar1.Maximum){
//progress bar is full

}
