IDebugDocumentText2::GetText
Retrieves the text from the specified position in the document.
HRESULT GetText(
TEXT_POSITION pos,
ULONG cMaxChars,
WCHAR* pText,
ULONG* pcNumChars
);
int GetText(
eumn_TEXT_POSITION pos,
uint cMaxChars,
IntPtr pText,
out uint pcNumChars
);
Parameters
pos
[in] A TEXT_POSITION structure that indicates the location of the text to be retrieved.cMaxChars
[in] The maximum number of characters of the text to be retrieved.pText
[in, out] A pointer to a buffer that is to be filled in with the desired text. This buffer must be able to contain at least cMaxChars number of wide characters.pcNumChars
[out] Returns the number of characters actually retrieved.
Return Value
If successful, returns S_OK; otherwise, returns an error code.
Example
This example shows how this method can be called from C#.
using System.Runtime.Interop.Services;
using Microsoft.VisualStudio;
using Microsoft.VisualStudio.Debugger.Interop;
namespace Mynamespace
{
class MyClass
{
string GetDocumentText(IDebugDocumentText2 pText, TEXT_POSITION pos)
{
string documentText = string.Empty;
if (pText != null)
{
uint numLines = 0;
uint numChars = 0;
int hr;
hr = pText.GetSize(ref numLines, ref numChars);
if (ErrorHandler.Succeeded(hr))
{
IntPtr buffer = Marshal.AllocCoTaskMem((int)numChars * sizeof(char));
uint actualChars = 0;
hr = pText.GetText(pos, numChars, buffer, out actualChars);
if (ErrorHandler.Succeeded(hr))
{
documentText = Marshal.PtrToStringUni(buffer, (int)actualChars);
}
Marshal.FreeCoTaskMem(buffer);
}
}
return documentText;
}
}
