Remote Console connection problem

The Remote Console stops responding after an attempt to connect to a non-existing server or to a server which is shut down. This behavior might not be reproducable.

mwconsole.exe /server MyServer:8000



Edit

Startpage displays failure #500-2 (WebClient login disabled) to users in role IsRoleIgnoreLoginDisabled

As default, users with role IsRoleIgnoreLoginDisabled should be able to access the webclient even if login is temporarily disabled. Despite all expectations, this feature doesn't work when the webclient is accessed from the Startpage.

This behavior is (currently) by design. The purpose of IsRoleIgnoreLoginDisabled role is to give a chance of an after-update testing to the admin - before any other user is allowed to log in. Resolution: The administrator should access the webclient site directly if the login is disabled.

Error 0x80004005 while opening (any) access database by WebClient application

aby sa dali otvarat access databazy kontom ASPNET_MEX, musi mat toto nastavene prava na zapis do documents and settings\nazov masiny\aspnet\local settings\temp, inak to vyhodi 0x80004005 chybu. Moze sa ale stat, ze adresar nazov masiny neexistuje. Ak bola masina v minulosti premenovana, ostava stary folder a oledb stale pouziva tento stary, aj ked sa uz masina vola inac. confusing.



Edit

"Show server screenshot" menu item reports The handle is invalid

= This problem has occured at several machines with Windows 2003 Server enterprise edition installed.

Location: mwengine.core.dll!MWEngineConsoleServices.GetScreenshot - CopyFromScreen method call.



Edit

Multiple installations of Datacquire are not allowed by installer

Although the engine controller and web client architecture allows to handle multiple parallel installations (e.g. sharp webclient in one IIS virtual directory and another version of webclient in other virtual directory), multiple installations are refused by the installer utility. This has no priority and will be solved on demand.



Edit

Web Client installation - web site alias can't contain spaces

An error message appears during the installation if the specified web client alias contains spaces. (can't find folder c:\windows\system32\ ...)



Edit

Clipboard operations are ignored

Common copy-paste operations on the server may silently fail when there are more users connected and working with the web client. Clipboard is an essential part of Datacquire data interchange logic and this behavior is by design. Local usage (laptop installations for presentation purposes etc.) doesn't cause this problem because the clipboard is not shared among more users.



Edit

MEX Client process instances don't revert to a "Normal" priority class after login

When the Engine Controller runs in IntelliSleep mode, all MEX clients not reserved by user ("free servers") run with idle process priority class to save server resources. Priority class is changed back to Normal each time a MEX client instance is reserved to a user during logon. In some cases, the priority class remains idle. The reason is unknown, .NET Framework simply ignores the call and no error is reported.



Edit

Load Balancer stops responding - https + proxy

Basic SSL support was introduced in Datacquire 2008 R04. The Load Balancer may stop responding (timeout) while trying to access the server using https protocol when the proxy server is specified in the configuration file. If you experience this problem, don't use any explicit proxy or a proxy taken from Internet Explorer settings (The "IE" value of the mode parameter). Disable the proxy in _balancer.config.mcfg by setting the mode parameter to "NONE", as seen below.

    <server disabled="false" id="WEB1" url="https://myserver.com/">
      <auth type="NTLM" username="IUSR_DATACQUIRE" password="password" domain="" passwordencryption="NONE"/>
      
      <proxy mode="NONE" host="" port="">
        
        <proxyauth type="" username="" password="" domain="" passwordencryption="NONE" />
      </proxy>
    </server>

(This is not a bug)

Diakritika v oknách Obľúbených položiek

V prípade, že je slovenská lokalizácia web klienta otváraná na počítači s anglickou verziou systému Windows, nefunguje diakritika v strome so zostavami správne.

Multiselect TreeCombo v kombinácii s favorites alebo cache.

Po otvorení zostavy s tým, že sú parametre automaticky nastavované z favorites alebo cache, sa síce vybraná hodnota v combe zobrazuje správne (... v prípade viacerých vybraných hodnôt), ale stav checkboxov po rozbalení stromu je rovnaký, aký bol pri poslednom ručnom výbere - neodrážajú teda aktuálne zobrazený stav v zostave.

Jedná sa o komplexný problém, ktorý je momentálne neriešiteľný, nakoľko strom nie je po otvorení zostavy takmer nikdy v plne rozdrillovanom stave (kvôli úspore pamäte a prenosového pásma) a preto sa aj tak nedajú označiť položky, ktoré práve nie sú rozdrillované.

Checkboxy v treeview teda nemôžu byť používané na zistenie aktuálne vybraných hodnôt.
