asp.net VB use htm to word , but when the download file is opening ,it got error



I used Word 365 to convert a WORD file into an HTM template for ASP.net Vb.
And the program will use this template when it is executed, and replace the text inside, and produce a new WORD file.



However, when this downloaded file is opened with 365, it will get an error.



"The file is corrupted and cannot be opened."



Can anyone help me fix this problem?



Here is my program


Dim htmlWrite As New StringBuilder
Dim dv1 As DataView = db_CE04.getdv_by_fk_ce01_aid(aid)
If dv1.Count > 0 Then
For i As Integer = 0 To dv1.Count - 1
htmlWrite.Append(IO.File.ReadAllText(Server.MapPath("~/html/In_service_or_leave/onbord_report.htm")))

htmlWrite.Replace("[internal_id]", title)
htmlWrite.Replace("[year]", year(now()))
htmlWrite.Replace("[form_text]", form_text)
htmlWrite.Replace("[form_no]", form_no)
htmlWrite.Replace("[employee_name]", employee_name")
htmlWrite.Replace("[law_id]", law_id)
htmlWrite.Replace("[sex]", gender)
htmlWrite.Replace("[unit_name]", unit_id)
htmlWrite.Replace("[position_name]", position_name)
htmlWrite.Replace("[position_level]", position_level_name & salary_level_name)
htmlWrite.Replace("[reason]", reason)
Next
End If

Dim word_name As String = "test"& "_XXXX(" & Now.ToString("yyyyMMddHHmmss") & ").docx"
Response.ClearHeaders()
Response.Clear()
Response.Expires = 0
Response.Buffer = True
Response.AddHeader("content-disposition", "attachment;filename=" & Server.UrlEncode(word_name))
Response.Charset = "UTF-8"
Response.ContentType = "application/ms-word"
Response.Write(htmlWrite.ToString)
Response.End()





You cannot put a ".docx" extension on an HTML file and then directly open it in Word. There is software available to manipulate Word documents on a server. Please note that Word itself is not suitable for the task.

Hint: if you save your Word document as a .docx file, you can open it with something like 7-zip and explore the contents. If you look in the "word" directory you will find a file "document.xml". If you edit that file and put it back into the zip archive then you can open it in Word and see the changes.

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

How to determine optimal route across keyboard

Clash Royale CLAN TAG #URR8PPP How to determine optimal route across keyboard I'm trying to automate the typing process in a video game. Players are given an on-screen QWERTY keyboard layout that they can navigate with the control stick (up, down, left, right) in order to select a letter to type. I was wondering if there was a module for Python (or some other resource I could explore) that would help my program find a path across the keyboard as it types each letter in a given message. In other words, if the first letter typed was "A" and the next letter was "B", the module would know that the program should move 1 space down on the keyboard and 4 spaces to the right. Currently, I have the program resetting to the "G" key after each letter is typed (allowing me to use fixed-directions as the program parses each character in the desired message). As you can imagine, this is quite inefficient and defeats the purpose of automating the typing in the fir
