Hi everyone,
I run into a tricky issue when I run cmd.exe using Process class in C#.
1)Here's the C# code,it run the specified .bat file in command-line:
m_BasicDataProc = new Process();
m_BasicDataProc.StartInfo.FileName = "cmd.exe";
m_BasicDataProc.StartInfo.CreateNoWindow = false;
m_BasicDataProc.StartInfo.UseShellExecute = false;
m_BasicDataProc.StartInfo.RedirectStandardOutput = true;
m_BasicDataProc.StartInfo.RedirectStandardInput = true;
m_BasicDataProc.StartInfo.WorkingDirectory = Path.GetDirectoryName(batchFilePath);
m_BasicDataProc.Start();
string batchFileName = Path.GetFileName(batchFilePath);
string ipLine = batchFileName;StreamWriter inputStream = m_BasicDataProc.StandardInput;
inputStream.WriteLine(ipLine);
inputStream.Close();
m_BasicDataProc.WaitForExit();
m_BasicDataProc.EnableRaisingEvents = true;
2)In the .bat file,it calls a .vbs file with the content pretty much like this:
option explicit
dim fso
Set fso = CreateObject("Scripting.FileSystemObject")
Dim CreateFile
Set CreateFile = fso.CreateTextFile("InstallScripts\CreateTriggers.sql", true)
......
CreateFile.writeLine(strStatement)
CreateFile.WriteLine
set CreateFile = nothing
set fso = nothing
//
I found that the file CreateTriggers.sql was created successfully,it means that the work of this .bat file is finished,but it's really odd that the application is still blocked by the code line "m_BasicDataProc.WaitForExit();" and could not exit. Has anyone been in same situation?
Anything you could help would be appreciated!

the batch file finished but cmd.exe is still running - that's what m_BasicDataProc.WaitForExit() is waiting for. Try executing the batch file directly instead of passing it as an argument to cmd.exe.

Hi,
Suppose that we have a handle to an unmanaged control (window), is there any possible way that we "Cast" that handle to a managed control (for example ListView)?
Regards,
Beirami
P.S. Control.FromHandle() and NativeWindow.FromHandle() are returning null.
|
|
|
|
|
No, of course not. Because while the underlying handle is probably the same thing, it's not an instance of the managed class, so you can't cast it into one. You may be able to attach an instance of the managed class to an existing handle, but I don't know if methods exist to do that or not.

no, you cannot create a exe file of asp.net C# web projects... only windows appliacations can be created as .exe or .msi files.
nudma wrote: what will be the requirements to deploy it on other computer having no asp.net
atleast .net framework is needed to deploy it on other computers...

Please read some basic books and please do not spam the forums with your questions. You are asking things that show you're at a level below beginner, you have no idea at all of what you're doing, or what the technologies you're using are for, or what they do.

Hi,
I have a Windows Application that contains 3 Comboboxes that's being populated by a SQL database. Those 3 boxes are "Countries", "States" and "Suburbs". I want to code the Comboboxes so that when you select a country, the state combobox will display states for that country and when you select a state you should be able to select a suburb within the selected state.
How can I go about doing this?
Thank you!!

Handle the comboboxes selection changed event and bind the next combo. If you use DataBinding, just update the datasource and control will reload items automatically.
|
|
|
|
|
Write IndexChanged Event for country and states dropdown. When you change the country dropdown index get all the associated states from the db and re-bind it to the state dropdown. Similarly when you change the state dropdown get all the related suburbs for that state from the db and re-bind it to suburbs dropdown.
Use valuemember and displaymember, so that it will be easy to fetch from the db.

Prakash N

hi,
i am new to this type of implementation what i need to solve is:
[gevec,geval] = eig(inv(S) * C); (this in matlab, i wish to do it in c#)
where S and c are 2-d matrices i have computed the value for.
Please let me know how can i solve this. Is there any library that can be of help...
Thanks...

I have no idea what you're trying to do here. You need to break this down into individual functions, and then look for hte C# equivelant. If the [gevec, geval] part is selecting a pixel value, read my image processing articles for details on how to do that in C#.

Hi if you could please let me know of some library that helps in solving matrices like the inverse of a 2-d matrix.
thanks

There are matrix classes built in to C#

Hi people
I was wondering whether anyone knew what button is used in Visual Studio as the "New" button? It looks like a normal button, but with a drop down next to it. I want to use a similar button in my application
Thanks

that is a menustrip. just look at toolbox -> menus & toolbars.

Add MenuStrip to your Project, then right click on it and click "Insert Standard Items"

Sorry guys, I didn't mention that I'm using WPF and MenuStrip is not available then. Didn't want to post this in the WPF forums cuz it seemed more like a general question. Can I maybe add a reference to Windows Forms or something to enable the Menustrip to work in WPF?

I have a VS2005 web project that provides file content download. Since some files are large I want to be able to pause/resume the download. I have added the 'Range' header and byte marker but am getting two problems:
1) File name is getting corrupted with a ',' comma character on the end of the file name (i.e. 'File.zip' shows in the save dialog as 'file.zip,' - could this be a cached file name suggestion?
2) The resume won't fire (possibly due to problem 1)
Environment is IIS6, VS2k5/C#/ASPX.
Have tried with FireFox (3.5.2) and Internet Download manager.
Here's the code - TIA
<br />
if (File.Exists(strFilePath))<br />
{<br />
byte[] buffer = new byte[Int32.Parse(Config.Settings["bufferSize"])];<br />
int length;<br />
long dataToRead, dataLength, bytesDownloaded;<br />
long start = 0;<br />
<br />
string range = Request.Headers["Range"];<br />
if (range != null)<br />
{<br />
range = range.Replace("bytes=", "");<br />
range = range.Substring(0, range.IndexOf("-"));<br />
start = Int64.Parse(range);<br />
}<br />
Response.Expires = 0;<br />
bytesDownloaded = 0;<br />
using (FileStream dlStream = new FileStream(strFilePath, FileMode.Open, FileAccess.Read, FileShare.Read))<br />
{<br />
if (start > 0)<br />
{<br />
dlStream.Seek(start, SeekOrigin.Begin);<br />
dataToRead = dlStream.Length - start;<br />
}<br />
else<br />
{ dataToRead = dlStream.Length; }<br />
dataLength = dataToRead;<br />
Response.AddHeader("Content-Disposition", "attachment; filename=\"" + dlStream.Name.Substring(dlStream.Name.LastIndexOf(@"\") + 1) + "\"");<br />
Response.AddHeader("Content-Length", dlStream.Length.ToString());<br />
length = dlStream.Read(buffer, 0, Int32.Parse(Config.Settings["bufferSize"]));<br />
while (dataToRead > 0)<br />
{<br />
if (Response.IsClientConnected)<br />
{<br />
Response.OutputStream.Write(buffer, 0, length);<br />
bytesDownloaded += length;<br />
Response.Flush();<br />
buffer = new byte[Int32.Parse(Config.Settings["bufferSize"])];<br />
dataToRead -= length;<br />
}<br />
else<br />
{ break; }<br />
}<br />
try <br />
{ dlStream.Close(); }<br />
catch<br />
{<br />
if (dlStream != null)<br />
{<br />
_errors.SendErrorEmail("download.aspx", "failed to close the file stream when user " + objUser.LoginID + " attempted to download " + strFilePath + ".", objUser);<br />
}<br />
}<br />
}<br />
<br />;
Thank you for taking the time to look at this
Tom

In that case, why not check out the Background Intelligent Transfer Service[^]?
