~Try something like this:
XmlTextWriter^ xmlTmp = gcnew XmlTextWriter(FileName, gcnew UTF8Encoding(false));
doc->Save(xmlTmp);
xmlTmp->Close();
The XML is stored in a DOM (Document Object Model). Note the Binary Order Mark supression - the UTF8 Encoding set to false. IF you leave this out then a couple of non printable characters appear in position 1:1. It upsets soapclient no end!

Hi!
Actually I've stored the XML contents(result of a HTTP Response) in a System::String^ variable. I've to write the contents of the String to an XML file. How to do this?
|
|
|
|
|
If the XML is properly formatted in the string, then just serialize the string to a text file and there you go.

The application has a screen size and resolution problem . What should be done since it looks very misery on desktops .
|
|
|
|
|
How can anyone guess? Please try and explain your problem in more detail.

We need more details to even begin discussing this.
Are you asking how to determine the screen resolution? Can there be multiple monitors?
If so, I'd start with the Screens object in WinForms. Ex: System::Windows::Forms::Screen::AllScreens
Of course, you can also fall-back to Win32 calls to enumerate monitors and determine resolution and work area size from there too.

Here are the requested details :
I have the code and following error (C++ /CLI)
<br />
Rectangle ^ClientResolution = gcnew Rectangle();<br />
<br />
ClientResolution = Screen::GetBounds(); <br />
<br />
float CurrentWidth = 1366 ;<br />
float CurrentHeight = 768;<br />
<br />
float RatioWidth = ((float)ClientResolution->Width / (float)CurrentWidth );<br />
<br />
float RatioHeight =((float)ClientResolution->Height / (float)CurrentHeight);<br />
<br />
this->Scale(RatioWidth,RatioHeight); <br />
// error C2661: 'System::Windows::Forms:: Screen::GetBounds' : no overloaded function takes 0 arguments
|
|

|
|
There can be more than one monitor but if you only care about the primary monitor, try this:
Rectangle^ ClientResolution = Screen::PrimaryScreen->Bounds;

Thanks John also about the point which you indicated. Hovewer this time application's all windows are maximised which is actually not much preferable. I guess you already have a better idea to fix
the problem. Let me know please.
|
|
|
|

We still don't have enough info to guess the problem you're trying to solve.
Based on your code and follow-up here's what I think you are saying:
You have an application with maximized windows but they do not cover the entire desktop and you would like them to. What should you do to make them cover it? ie. you want a full-screen app.
OR possibly...
The application windows are maximized and hiding things and you want them scaled smaller?
OR
neither of these. Please add some more detail about what the current situation is and what the desired situation is.

In which case why not check out the definition of the method you are calling here[^]?

It's allright Screen::GetBounds(this->ClientRectangle)
Suprisingly it didn't work well. The width of the forms just became a little smaller.That's all.
The application still has a screen size or resolution problem. I am really confused.

Me too, as you have not made clear exactly what your problem is.

Sorry i could't see the post. Of course , i am going to explain a simple version of my problem on an empty project. It is a C++ /cli desktop application.( .NET 3.5 )
On development machine (1280 by 720 pix) :
The application has two forms and a button.All form states are normal(default setting)I just customized to their sizes 100x150 and 150x100. That's all.
On client machine (1024 by 768 pix) :
A copy of the application's .exe was copied and clicked. It seems that initially all forms became maximized unexpectedly.
Any idea ?

Not really, I have not seen this problem. I can only suggest you check all your settings in your forms and start up code to ensure nothing is maximising the windows.

Hi!
I've to get the string from the String Table. I used the following code:
wchar_t myDocs[1024];
::LoadString(NULL,IDS_USERNAME_CH,myDocs,1024);
It shows the following error:
error C2065: 'IDS_USERNAME_CH' : undeclared identifier
I've to read the string(with ID IDS_USERNAME_CH) from the string Table and set the Text to a label. How to do this in C++/CLI?
|
|
|
|
|
That message seems fairly clear, check where have you defined IDS_USERNAME_CH and make sure it is included in the module you are trying to compile.

Hi,
I have
System::String ^ St = gcnew System::String("Hey ho!");
std::string str("standard");
St = str;
The only way I can make it work is by doing gcnew again St = gcnew System::String(str.c_str()); but I'm guessing this is not the right way. All the examples I have found tell how to do this when creating a new instance of System::String but none how to do it with an existing one.
|
|
|
|
|
System::String() has no constructor that accepts a std::string Try this:
St = str->c_str();

Tried it, no good.
error C2664: 'void System::Windows::Forms::Control::Text::set(System::String ^)' : cannot convert parameter 1 from 'const char *' to 'System::String ^' <br />
|
|
|
|

Sorry, I guess there is no simple way to do this other than :
St = gcnew System::String(str.c_str());

Fair enough. That's what I'd done, but... am I not re-allocating memory without freeing it first?? (I have to do it for a dozen of strings!)

It depends on the actual structure of your code. I think a more pertinent question would be: why are you using both std::string and System::String when you only really need one of them, probably the latter. For example code such as:
std::string str("Some string");
System::String ^ st = gcnew(str.c_str());
serves no real purpose, in that the std::string is totally redundant.

what about
St = gcnew String(str);
or
using namespace System::Runtime::InteropServices;
...
...
St = Marshal::PtrToStringAnsi((IntPtr)str);

Hi!
I've set the Text to my label from an XML file. I need to set a chinese word to a label. Here is my XML file contents:
<?xml version="1.0" encoding="UTF-8" ?>
<Remember>游戏目的是使两手牌的点数越比庄家接近</Remember>
The chinese word is for test purpose only(may not be meaningful word). Here is my code for reading this tag and setting the text to a label.
XmlDocument ^ Config = gcnew XmlDocument;
if(System::IO::File::Exists("Config.xml"))
{
Config->Load("Config.xml");
}
XPathNavigator ^ nav = Config->CreateNavigator();
XPathNodeIterator ^ iter;
iter = nav->Select("download/Remember");
while(iter->MoveNext())
{
System::String ^ ConfigText = iter->Current->Value;
ConfigText->Trim();
}
System::Runtime::InteropServices::Marshal::StringToHGlobalUni(ConfigText);
m_pRemember->Text = ConfigText;
While I execute the program only boxes are displayed in place of the chinese characters. If I open the XML file in a browser, the chinese characters are displayed. What else to do to display the chinese language?
