Embed a resource to a static library (nothing is impossible)

I needed to embed a resource (icon) to a static library so we can deploy just the .lib and .h files with no need to include any graphics or .rc files.

I wanted my static library to be used by any application including such that don’t have any graphic user interface, i.e. Console applications, etc.

I posted a question in Stack Overflow and Code Project and the responses were: That’s not possible…

Here is the question I have posted:

Is there a way to embed resources (such as icons, dialogs) in a c++ (Win32 API) static library? My purpose is to embed an icon in the static library in a way that functions that use LoadIcon will work as if it was a normal .exe so the main application can only link to the static library and include a header file, with no requirement to add other files such as .rc files, or .ico files, etc. Clearly the main application who uses the static library doesn’t have this resource so LoadIcon will fail, however I was wondering if there is a workaround to make it work. A static array with the icon data can work as long as the standard API calls (such as LoadIcon) will work.

To explain further, the person who will be using the static library will only have 2 files: .lib and .h and will not have any .rc file


Comments that followed:

“It is not possible, you can stop looking. Consider a DLL project instead.

At Code Project I was pointed to the following Stack Overflow thread:

” I read them but we wish to deploy 2 files: .lib and .h. These solutions require deploying the .rc file and having whoever uses our static library to link / include it as well.”
“Then there is no solution from my point of view.
The SO thread covers it all.”

Here is the solution I have found after some research I found a way. Using my method, an icon can be used as an integral part of a static library and such library can be used by any type of application, including a console one (which doesn’t have any resource segment whatsoever).

1. Icon is converted to a static array of BYTE. bin2c can be used for that.

2. Data is converted into a HICON handle. Here is how I have done that:

HICON GetIcon()
   DWORD dwTmp;
   int offset;
   HANDLE hFile;
   HICON hIcon = NULL;
   offset = LookupIconIdFromDirectoryEx(s_byIconData, TRUE, 0, 0, LR_DEFAULTCOLOR);
   if (offset != 0)
      hIcon = CreateIconFromResourceEx(s_byIconData + offset, 0, TRUE, 0x00030000, 0, 0, LR_DEFAULTCOLOR | LR_DEFAULTSIZE);
   return hIcon;  
3. GetIcon is used instead of LoadIcon.
Instead of calling:

I call

m_hIcon = GetIcon()

To test it, I created a Console application and a new static library. I added to the static library the XMessageBox class which allows using a custom icon.
The Console application just calls a function located at the static library and the icon is displayed!

Flawless Integration with PayPal

We have recently added a unique feature to Wizdome: payment processing embedded in your program using just few lines of source code.

Wizdome has a built-in payment processing engine which allows you to accept payments from any credit card holder (regardless of being a PayPal customer) and pay for unlocking your software or for specific features. As part of Datattoo Recovery, one of our other products, the customer can pay per each MB of successfully restored data.

To process payments you need to choose 2 routes:

  1. Apply as a PayPal developers and obtain your own PayPal credentials
  2. Use Wizdome credentials and receive all payments from Secured Globe, Inc.

Technically, the SG_PayPal API is used as described below. Following, your program can continue as before, while Wizdome will continue monitor the status of each payment initiated and in the event of a successful payment to a Pending Transaction, the credit (“max” value) of the associated Restriction, will be updated accordingly, so if your program checks the allowed maximum value per each per-defined Restriction, the value will become higher and your software can give additional access flawlessly.

Void InitPayPal(BOOL Sandbox, LPTSTR User, LPTSTR password, LPTSTR signature, LPTSTR successUrl, LPTSTR failedURL)

Sandbox – indicates whether you are testing your integration using PayPal's Sandbox account, or going live.

User – your PayPal user name

Password – your PayPal password

Signature – you PayPal signature

successUrl – a url leading to a web page which you wish to be shown after successful payment.

failedURL – a url leading to a web page which you wish to be shown after failed / cancalled payment.

Initiating a payment

When you wish to initiate a payment, you call

BOOL InitiatePaypalPayment(int nUnits, int PricePerUnit, LPWSTR UnitName, LPWSTR RestrictionName)

nUnits (integer) - number of unique needed to be purchased

PricePerUnit (integer) - cost per each unit (in default currency).

UnitName (string) - the name of the unit to be purchased

RestrictionName (string) - optional - the name of any restriction tied to this transaction

For example: if you would like a data recovery software to allow recovery of 15 MB for the price of $15, and provided that a Restriction named “MB_RESTRICTION” was defined, you call this function using the following parameters:



By default the currency used for transactions is USD, however that can be changed.

Tying a transaction to a Restriction

Wizdome allows you to tie a transaction (payment) to a Restriction. When you do so, the user will be able to lift or change a Restriction by making a payment and without having to switch versions, restart your program or restart any work done by your end-users.
