Hope this example can help you:
Process p = new Process();
p.StartInfo.FileName = "cmd.exe";
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardInput = true;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardError = true;
p.StartInfo.CreateNoWindow = true;
if (p.Start())
{
p.StandardInput.WriteLine("net use " + strFileName + " " + strPwd + " /user:" + strDomain + "\\" + strId);
p.StandardInput.WriteLine("exit");
p.WaitForExit();
string ReturnText = p.StandardOutput.ReadToEnd();
if (ReturnText.IndexOf("成功") >= 0)
Dts.TaskResult = (int)ScriptResults.Success;
else
throw new Exception("fail");
}
else
throw new Exception("fail");

Hi,
I am using iTextSharp to read & write the data to pdf-forms.It works good for reading from pdf-forms.
But when i write data to pdf-forms(programmatically) it fills data to pdf-forms successfully but when we try to
add data(manually) to pdf-forms, it don’t saves data to pdf-forms & gives error as

Who marked this as a Good Question?
Also, if you are using Adobe Reader, bypassing the reader extensions requirement is a violation of the Adobe License which is surprisingly very strict.

You might want to check out this article series for info on FileSystemWatcher:

Part 1 of the article discusses the actual code, and Part 2 shows some interesting results using the sample application that is provided in Part 1.

Maintain a record of where you left off and pick up from there.
That's what I do.

Has anyone used this "Range.BorderAround2" when making the border line around the cell range? I believe that it caused crash with this error message: "Exception from HRESULT: 0x80020003" which is "DISP_E_MEMBERNOTFOUND". I'm not quite sure if this is due to the other pc that has office 2003? I've included the v14 dll file in the executable directory.
I used the 3 lines below and it caused the error exception mentioned above.
I'm using the Microsoft.Office.Interop.Excel v14 (for MS Office 2010).
cellRange = oSheet.get_Range(oSheet.Cells[3, 10], oSheet.Cells[15, 11]);
cellRange.BorderAround2(Excel.XlLineStyle.xlContinuous, Excel.XlBorderWeight.xlThin, Excel.XlColorIndex.xlColorIndexAutomatic, 1, 1);
I had to use the lines as shown below and it works fine...
cellRange = oSheet.get_Range(oSheet.Cells[3, 10], oSheet.Cells[15, 11]);
cellRange.Borders.LineStyle = Excel.XlLineStyle.xlContinuous;
cellRange.Borders.Weight = Excel.XlBorderWeight.xlThin;

BorderAround2 didn't show up until Office 2010. It's also not meant to be used by your code.
|
|
|
|
|
OK, thanks for the response... my workaround will do the job for now. Funny is that when I was typing in the code, it did show BorderAround2 method... Question is why did they implement this method?
Geez whiz!
|
|
|
|
|
Because it's exposed by the Interop and public. It's just not meant to be used by your code, per the documentation on the method.

Can you point me to the location of this documentation?
Much appreciated!

I fore sure have a common task but I need some help in best practice in my topic.
How should read a file from an ASP.NET site and store it in a SQL Server.
Should I read it in as a byte[] and use varbinary(max) as database column type?

Imagine you sitting in a car, and all of a sudden the radio takes over your wheel and brakes. The user wouldn't even be able to click away any popups (like the ones generated by Windows', reminding you that you need to update)
Yes, it's possible. You could prevent input by filling the screen with a large form and hiding the cursor, like a screensaver. No, that still means that I can abort the operation, since there's always a reset-key on the PC.

As the previous answer mentions removing all mouse input is not a good idea. However the best that you can achieve is to ignore mouse input messages for your app for certain conditions, for example you should still accept mouse clicks to close the application.
The simplest way to do this is to not process OnClick events etc. on your form when a specified condition is met
e.g.
private void button1_MouseClick(object sender, MouseEventArgs e)
{
if (_allowMouseClicks)
{
}
}
or even more simply if it is a different form at specific point only support Keydown etc. events...
Alternatively you could override the WndProc for your form and trap the mouse messages here and test against a condition. However overriding the Wndproc isn't that simple a task, but if its the way you want to go have a look at this[^]

It is generally not a good idea to attempt to force users of your software to behave the way you want them to by limiting their ability to use or control your software through conventional means. They will simply stop using your software or complain to management that it doesn’t work and you’ll end up having rewrite the code, or worse yet, have someone else rewrite your code. (I do not wish to count the number of times I’ve been tasked to do just that.) Be mindful that removing control from the user is the goal of malware and virus writers, we know how popular folks like these are.
You should create a user interface that makes it easier to enter data or interact with your controls by automatically moving the focus to the next desired control so that they don’t have to use the mouse. Sometimes it is unavoidable when certain user actions interfere with the application processes such as collecting live streaming data and moving the form can cause an interruption to the data stream. For these situations I allow the user to place or move the form when it is not collecting data, but lock it when it is. It crucial then to inform the user that this behavior exists so that it does not catch the user by surprise and have them do something like hitting the reset button because they think the PC is broke.
Rhuros first suggestion is the one that I use when someone attempts to move a form when it becomes necessary to prevent it from being moved during a critical process.
It was broke, so I fixed it.

On a thread I hope. That shouldn't be affected by form movement.

We use RS232 to collect raw A to D data from products when they are being tested for FDA compliance. The form, the Comm, and the file I/O are all invoked using their own thread. There is a momentary pause as the screen refreshes each position of the form while being moved, and depending on the machine, we've had problems when a user either moves a form to another part of the screen or decides to surf the internet or play solitaire because the testing is so boring. It is simple matter of resources, especially of time.
When a company spends in the tens of thousands of $$ for testing, it is best to mitigate any possibility of data corruption. This is mission critical stuff in the medical device industry.
The intent of my post is that a person should not prevent a user from being able to use normal interface operations such and clicking a button with a mouse or moving a form. I gave an example where a programmer could be instructed to do a little user action prevention.
It was broke, so I fixed it.

Hello,
Can anyone tell me how to use a List of strings inside a struct? I get the 'Object reference not set to an instance of an object.' error.
public Form1()
{
InitializeComponent();
}
struct testStruct
{
public List<string> sList
{
get;
set;
}
}
private void Form1_Load(object sender, EventArgs e)
{
testStruct aTestStruct = new testStruct();
aTestStruct.sList.Add("test");
}
Thank you!

You've not instantiated the List anywhere. This has nothing to do with it being inside a struct - the same would have happened if your list was inside a class.
You can fix this by first creating the List.
testStruct aTestStruct = new testStruct();
aTestStruct.sList = new List<string>();
aTestStruct.sList.Add("test");
However, a few pointers
0.1) Naming convention for C# would instruct that your property is called List instead of sList.
0.2) Be careful using structs, they have some hard to understand facets - if in doubt use a class.
0.3) Strictly speaking, a List should generally not be exposed by a public property. Consider whether the struct/class should instead expose just the interface, such as an Add method to add to an internal List.
