这是我的代码,但它不编译并给出两个错误:

error C2440: '=' : cannot convert from 'WCHAR' to 'WCHAR [2084]'     
IntelliSense: expression must be a modifiable lvalue    

我有下面的阅读链接,但它没有帮助我:

错误C2106:'=':左操作数必须是l值

[代码]:

#define ID_SysLink 500              
HWND hWnd;

LRESULT CALLBACK WndProc(HWND hWnd, UINT Msg, WPARAM wParam, LPARAM lParam)
{
switch (Msg)
{
case WM_CREATE:
    {
        HWND syslink_handle=0;
        syslink_handle=CreateWindowEx(0, WC_LINK, L"test syslink",  WS_VISIBLE | WS_CHILD , 10, 10, 100, 30, hWnd, HMENU(ID_SysLink), 0, 0);

        LITEM *pitem = 0;
        pitem->iLink = 0;

我想在tabcontrol中的标签页中添加一些控件，但它似乎会添加到所有页面中，并且默认情况下tabcontrol中没有标签页。

我已经阅读了下面的这些链接，但它们对我没有帮助，并且在其中的某些部分让我感到困惑。

我想根据'tmpnumstr'成员拆分'tmpstr'成员.这是我的临时解决方案,但我正在寻找任意'tmpstr'和'tmpnumstr'的一般解决方案.

string tmpstr = "New,Open,Exit,Copy,Cut,Paste,Help,About,"; 
string tmpnumstr = "3,3,2,"; // string of numbers

string[] tmpstrArray = tmpstr.TrimEnd(',').Split(',');

for (int i = 0; i < 3; i++)
{
    textBox1.Text += tmpstrArray[i] + @",";
}
textBox1.Text += Environment.NewLine;
for (int i = 3; i < 6; i++)
{
    textBox1.Text += tmpstrArray[i] + @",";
}
textBox1.Text += Environment.NewLine;
for (int i = 6; i < 8; i++)
{
    textBox1.Text += tmpstrArray[i] + @",";
}
textBox1.Text += Environment.NewLine;
