The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Using function from DLLs (crypt32.dll) in Delphi

Asked by TonyJix in Delphi Programming

Tags: delphi

Hi,

Crypt32.dll has a function named CryptProtectData. I would like to use that function to encrypt something. But I have no idea how.

In Visual Basic, you'd use something like:

---

Private Declare Function CryptProtectData Lib "crypt32.dll" (ByRef r_udtDataIn As DATA_BLOB, ByVal v_sDataDescr As String, ByRef r_anyOptionalEntropy As Any, ByRef r_anyReserved As Any, ByRef r_anyPromptStruct As Any, ByVal v_lFlags As Long, ByRef r_udtDataOut As DATA_BLOB) As Long

Dim udtDataOut As DATA_BLOB
Dim udtDataIn As DATA_BLOB

Call CryptProtectData(udtDataIn, "", ByVal vbNullString, ByVal vbNullString, ByVal vbNullString, 0, udtDataOut)

---

But what to do in Delphi? Anyone any idea how to get the result?
