Article

Initializes a VARIANT structure based on a string resource embedded in an executable file.

Syntax

PSSTDAPI InitVariantFromResource(
  [in]  HINSTANCE hinst,
  [in]  UINT      id,
  [out] VARIANT   *pvar
);

Parameters

[in] hinst

Type: HINSTANCE

Handle to an instance of the module whose executable file contains the string resource.

[in] id

Type: UINT

Integer identifier of the string to be loaded.

[out] pvar

Type: VARIANT*

When this function returns, contains the initialized VARIANT structure.

Return value

Type: HRESULT

If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

Creates a VT_BSTR variant. If the resource does not exist, this function initializes the VARIANT as VT_EMPTY and returns a failure code.

Examples

The following example, to be included as part of a larger program, demonstrates how to use InitVariantFromResource.

// HINSTANCE hinst;
// UINT id;
// Assume variables hinst and id are initialized and valid.
VARIANT var;

HRESULT hr = InitVariantFromResource(hinst, id, &var);

if (SUCCEEDED(hr))
{
    // var now is valid and has type VT_BSTR.
    VariantClear(&var);
}
