2.2Questions:Ntko Office Document controls cannot be loaded automatically

Cause Analysis: Controls cannot be loaded automatically mainly due to the following causes

1) security settings in the Local Internet option prohibit the download of signed ActiveX controls in the current zone;

2) The CodeBase property in the <object tag is specified incorrectly in the page that references the control, causing the browser to not download the Officecontrol.cab file;

3) The Officecontrol.cab on the server is destroyed, the correct signature is lost, or an incorrect version is used;

4) Although the Officecontrol.cab on the server is correct, there is a problem with the browser download. This may be caused by the incorrect configuration of some Web server's mime, causing the server to send Officecontrol.cab to the browser in the form of a binary file;

5) security settings in the Local Internet option that do not allow ActiveX controls and plugins to be run in the current zone;

6) may also be caused by Microsoft's patch, or other anti-virus software or filtering software to prevent the installation of the control;

Workaround:

1) Confirm the security settings in the local Internet Options, allow download of signed ActiveX controls, and allow ActiveX controls and plug-ins to run.

2) Confirm that the codebase= portion of the <object tag in the Web page that references the control correctly points to the url[of the Officecontrol.cab file on the server relative to the current Web page or the relative server root].

3) from the browser address bar directly enter the URL of the Officecontrol.cab file on the server, including the host name, confirm that the browser appears download prompt and after downloading the saved Officecontrol.cab file, right-click on the Properties, in the dialog box appears with " Digital signature, and the signature is correct.

2.4   problem : "You did not install Office correctly or requested to create an OLE document type that is not supported by the system" error when loading a document  

Workaround:

This error is because the interface is not registered. Has nothing to do with the control itself. You can try 1, open the Windows WordPad application, and choose to insert the Word document object. If this error occurs, you can be sure that the Office installation is a problem, or because Ole32.dll is not registered. 2, you can try to run "Regsvr32.dll" at the command line, and then try again. 3, if not, you can completely uninstall office, reinstall.

2.5   problem : Why a control sometimes loads a document that is blank and sometimes load normally

This may be a direct call to Openfromurl/beginopenfromurl in the body, but at this point the control is not fully initialized /loaded, so there is a blank. Workaround: You can invoke the JS function in the <body onload= "..." > to make sure that after the browser loads the control, the Openfromurl/beginopenfromurl is called in the JS function. So that it can be solved.

1) For unknown reasons, the document is damaged, you can open the document from the local, save a copy to try to open the control

2.7   problem : File Transfer error occurs when you use a document control to open a document above a server

Workaround:

The control object . Openfromurl (URL); The parameter URL must be able to return the binary data stream of the standard document. It can point directly to a Word document or page on the server (this page reads the data stream of the document and returns it to the client).
There are several scenarios in which errors occur:
1:url error. If the URL is not the problem in the browser's address bar directly enter the URL corresponding to the full URL should be able to download the Word document. If there is a problem with the URL, the control cannot get the document data and will prompt for "file transfer error."
2: Coding problem. For example, in the URL with Chinese characters, the browser URL encoding to the URL is corrupted. The server will certainly not be able to return the correct word binary stream based on the URL being compromised. You can encode the URL by setting the isuseutf8url=-1 of the control (that is, using UTF8). Sometimes even setting up isuseutf8url=-1 does not solve the problem. Based on experience, you can call Url=escape (URL), re-encode the URL once, and then call Openfromurl (URL).
3: The server settings themselves do not support Chinese URLs. For example, the Tomcat server, the server configuration file can be set URL encoding, and some encoding format is not supported in Chinese. In this case, you need to reset the URL encoding format that supports Chinese.

Save document back to Server times "file transfer Error" The return value of the Savetourl () method is the content of the entire page when the URL points to the end of the page. If the background URL program has an error, the save is unsuccessful. The control will prompt for "file transfer Error" and the return value of the Savetourl () method contains an error message. You can view the error message and debug the URL page by using code similar to the following: var resttml = control object. Savetourl (URL,..); alert (resttml);

2.8 questions: the control uses a period of time after a sudden prompt "The Ntko Office document control that you are running is a demo version that has expired and cannot continue to be used." (. NET version)

Workaround:

3 files copied to the standard version of the deployment package, overwriting the files under the corresponding path for the project group.

2.9    problem : There's nothing wrong with testing anywhere else. when the document is saved appear not known error

Workaround:

This can be caused by opening a document Openfromurl The second argument or beginopenfromurl the third read-only property to true so that the document cannot be saved back to the server , so the solution is to set this parameter to False to resolve;

2.10 Problem: When the client Office version contains 2003, 2007, and 2010, how to handle compatibility issues when saving documents

Workaround:

because a low version of Office cannot be compatible with a high-version Office document format (such as office2003 cannot open 07 and 10 documents), it is recommended that you use the Saveasotherformattourl method when you save the document. This method is used to save the document to a specified URL in a file in a different format. In addition to the first argument, the format of the other parameters and the return value are consistent with the parameters of the Savetourl method.

The first parameter indicates the type of file to save:
