Semantic Versioning Starting with Chilkat 10.0.0

Pinned September 26, 2024

Starting with the v10.0.0 release (end of September 2024), Chilkat moves to standard semantic versioning.   Prior to this release, for various technical reasons, Chilkat was stuck with versions 9.5.0.xx, where only xx changed. For this first leap to semantic versioning, where the major version changes to 10 (from 9), there are no backward incompatible changes.  […]

File Upload Limits in IIS7 – Increasing the Size Limit

November 20, 2008 in Uncategorized

A web application running in IIS7 on Windows Server 2008 will reject any upload that is larger than 30MB. This is the default size limit for IIS7. To increase the maximum file size, add the following code to <system.webServer> in the web.config file: (This example sets the limit to 500MB) <security> <requestFiltering> <requestLimits maxAllowedContentLength=”500000000″ /> […]

No socket exists for sending

November 20, 2008 in Uncategorized

If the error message “No socket exists for sending” is found in the LastErrorText, it means that the component is not connected to the server. For example, if Ftp2.PutFile is called to upload a file, but Ftp2.Connect is never called to establish the connection, the “No socket exists for sending” would be found in the […]

Utf8 C++ property allows for utf-8 or ANSI “const char *”

November 19, 2008 in Uncategorized

All Chilkat C++ classes have a Utf8 property. For example: class CkEmail : public CkObject { public: CkEmail(); virtual ~CkEmail(); … bool get_Utf8(void) const; void put_Utf8(bool b); … const char *addFileAttachment(const char *fileName); … }; The Utf8 property controls how the bytes pointed by “const char *” arguments are interpreted.

x64 ActiveX Registration on Windows 2008 Server

November 19, 2008 in Uncategorized

For the most part, a 32-bit Chilkat ActiveX DLL will run on a 64-bit computer. However, there is an issue (to be explained here) that requires the ActiveX to be built specifically for x64. Chilkat provides separate 64-bit ActiveX’s on it’s downloads web page, and these should be used on x64 systems. The problem occurs […]

Exchange Server Unencrypted Login/Password w/ POP3

November 19, 2008 in Uncategorized

Question: We are currently using Chilkat to retrieve e-mail for a number of our applications. A client of ours has updated their exchange mail server and they have disabled the pop3 service because of authentication issues (the user/password is sent unencrypted and would be a threat). Are there any other possibilities within the scope of […]

ChilkatDotNet2.dll on x64 from a Windows Service

November 19, 2008 in Uncategorized

Here’s the secret to getting the .NET runtime to load the ChilkatDotNet2.dll from a Windows Service: It must be installed in the GAC, but there’s a separate GAC for 64-bit assemblies: (with permission from the Chilkat customer) I was able to find a solution to this. I’m running a 64-bit version of Vista, and there […]

Bitvise WinSSHD request “dumb” PTY problem

November 19, 2008 in Uncategorized

I’ve found the following scenario when testing SSH shell with the Bitvise WinSSHD server. If a request for a “dumb” pseudo-terminal is sent via the Chilkat SSH component’s SendReqPty method, the WinSSHD server responds with a success status, however, it really fails. The SSHD log has the following error message: 000000000116 2008-11-19 16:29:41.185Z WinSSHD 5.01 […]

November 18, 2008 in Uncategorized

It is possible to use string literals within your C++ code — as long as you save your C++ source file using the utf-8 character encoding. For example, open a .cpp source file and add this line: CkString str1; str1.appendU(L”京”); When you try to save the .cpp source file, you may get a message such […]

Setting the Initialization Vector for Encryption

November 18, 2008 in Uncategorized

Question: We’re trying to sync up our Chilkat component with another encryption component but can’t get the initialization vector to match. Is that compiled into the Chilkat module, or can it be changed via a component property? Answer: Yes, the Chilkat encryption component provides the “IV” property. The type depends on the programming language: ActiveX: […]

Question: Do you have any suggestions on this error? I have all the service packs installed for server 2003. Do I need to send shorter strings? I don’t seem to have any issues with small messages.
