AxWebBrowser - problem with caching website.

Re: AxWebBrowser - problem with caching website.

Hi Vjay,

I am not sure, I thought I had the same problems, but you can try the

axwebbrowser.re fresh2(3)

method, that should do it, but I am in doubt.

Tell me if it works, will you?

AxWebBrowser - problem with caching website.

I don't know how to do what you want to do.
I just wonder if Microsoft have designed their products
to avoid programmers being able to do that easily because
it might allow an ill intentioned programmer to overload
any server he wanted to, just put a very short timer and
set up a few clients to load pages from the server every
few milliseconds. I am not suggesting you have any
intention of wanting to do that, just that it might be
why it is difficult to find a technical solution to do it.
In fact I don't have an answer to your question, I am
just curious to know if it is possible to do it.
Best Regards, Tony[color=blue]

re:AxWebBrowser - problem with caching website.

Daer Cor,
refresh2 doesn't work either?

Tony:
you might be right, but it wouldn't let me update them even in 5
minutes intervals. Sux badly.

Any other ideas?

Thanks for trying to help.

Re: AxWebBrowser - problem with caching website.

you might try changing a setting in Internet Explorer - Tools/Internet
Options - then under Settings button - Check for newer versions of stored
pages - select "Every visit to the page". I believe this is stored in
registry @ Current User\Software\M icrosoft\Window s\CurrentVersio n\Internet
Settings\SyncMo de5 so that you can check value (and change) in program if
needed. (key doesn't look it exists until you first change the value in
Internet Explorer)

re:AxWebBrowser - problem with caching website.

These are exactly the same problems as I have experienced with vb.net
while trying to use smtp authorization.. .
simply wouldn't work

I hope someone will help you.

re:AxWebBrowser - problem with caching website.

Dan,

I tried what you suggested but Current
User\Software\M icrosoft\Window s\CurrentVersio n\Internet
Settings\SyncMo de5 doesn't exist in win xp home registries, or I am
blind but really can't find it.
I was able to get only to Current
User\Software\M icrosoft\Window s\CurrentVersio n\Internet
Settings\ but 'SyncMode5' is not there.

Then, I have changed settings in internet explorer as per what you
said, and it finally fixed the problem. Now I would need to figure
out how to do this programmaticall y, is there any other way to do
this? or any other path in registries?

Thanks for all you help.
Vjay

Re: re:AxWebBrowser - problem with caching website.

double-check to see if the registry key is there now - I just checked a Win
XP home machine - it didn't exist initially but once I changed the setting
in IE - it appears in the registry.

I am running this on an internal system that I have control over- if I
needed to distribute this to a client I might be worry about counting on
that registry key always existing (and working) with every upgrade to
windows - maybe someone else can chime in on using this...

anyway this is what I use to check in code - you can change GetValue to
SetValue to actually change the key.

Imports Microsoft.Win32

Dim regKey As RegistryKey
Dim dResult As Int16
regKey =
Registry.Curren tUser.OpenSubKe y("Software\Mic rosoft\Windows\ CurrentVersion\ I
nternet Settings", True)
dResult = Convert.ToInt16 (regKey.GetValu e("SyncMode5" , 0))
If dResult <> 3 Then
MessageBox.Show ("Browser not configured properly")
End If
regKey.Close()

re:AxWebBrowser - problem with caching website.

Thanks Dan.
This is really good to know.
Thanks for your time.

I hope someone will find out how to refresh the axwebbrowser properly,
so I don't have to go through these troubles with setting registries
and checking if they exist or not... that is not the best...

there must be some programmatic way of doing it using axwebbrowser
properties...

hm..

Hope someone can find this challanging...

I did already, but the webbrowser is just using IE.
I thought that in the next version of VB.net there will be a seperated
webbrowser.

But I was hoping I was wrong and you did find the way

I did not do what Dan was advising, for two reasons

Because of that this Microsoft can change it everyday if they think it is a
security problem, without have to think on other developers.
Because the user does not know what you are doing in his settings and that
can give problems (When it is an "in house" program that is a less problem I
asume)

:-))

re:AxWebBrowser - problem with caching website.

Cor,
this application will be eventually used just for my own purposes as
it looks right now.
So I assume this is the end to this debate?
No one else has anything else to add?

WebBrowser1.Nav igate2 http://www.yahoo.com navNoReadFromCa che

not sure on the syntax as I dont have a book by me.

Re: AxWebBrowser - problem with caching website.

A Refresh2 method accepts an argument that determines the refresh level.
This refresh level argument can have one of the following values:

REFRESH_NORMAL 0
REFRESH_IFEXPIR ED 1
REFRESH_COMPLET ELY 3

Thus

Dim REFRESH_COMPLET ELY As Object = 3
axWebBrowser1.R efresh2( REFRESH_COMPLET ELY)

Let me know if this helped.

re:AxWebBrowser - problem with caching website.

Ok I wrote it like you suggested

Dim REFRESH_COMPLET ELY As Object = 3
AxWebBrowser1.R efresh2(REFRESH _COMPLETELY)

It gave me unspecified error it simply crashed.

Then I tried to load the page first and than refresh it, like this:

[code:1:51d5a1a4 18]
AxWebBrowser1.N avigate(TextBox 1.Text)
Dim REFRESH_COMPLET ELY As Object = 3
AxWebBrowser1.R efresh2(REFRESH _COMPLETELY)
[/code:1:51d5a1a4 18]

But it still crashed on me. Refresh2 is probably not the best idea...

Then I tried:

[code:1:51d5a1a4 18]
AxWebBrowser1.F ocus()
SendKeys.Send(" F5")
[/code:1:51d5a1a4 18]

Nothing works.
Drives me mad :(
