Running into an issue where I can write to a specific folder but can't access it. Tried about everything I can think of with no luck.
foreach (ViewSchedule vs in col.Cast<ViewSchedule>())
{
if (vs == null)
{
continue;
}
Thread.SpinWait(1);
{
vs.Export(_export_folder_name,
vs.Name + _ext, opt);
}
vs.Dispose();
}
Any help/guidance would be greatly appreciated.

I have a Console Application which is invoking SSIS Package.Below is the code which is working Fine.
public static void ExecuteSSIS_Staging()
{
DataAccessLayer objDAL = new DataAccessLayer();
LogManager_SSIS objlogM = new LogManager_SSIS();
String strDestinationFilePath = System.Configuration.ConfigurationManager.AppSettings.Get("FileDownloaded");
try
{
Package pkg;
Application app;
DTSExecResult pkgResults;
MyEventListener eventListener = new MyEventListener();
string staging_pkgLocation = System.Configuration.ConfigurationManager.AppSettings.Get("SSIS_Staging_Filepath").ToString();
app = new Application();
pkg = app.LoadPackage(staging_pkgLocation, eventListener);
pkgResults = pkg.Execute(null, null, eventListener, null, null);
if (pkgResults == Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Success)
{
Console.WriteLine("Success");
}
else if (pkgResults == Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure)
{
string err = "";
foreach (Microsoft.SqlServer.Dts.Runtime.DtsError local_DtsError in pkg.Errors)
{
string error = local_DtsError.Description.ToString();
err = err + error;
}
throw new Exception("Error Occurred while executing the SSIS Staging package:" + err);
}
}
catch (Exception ex)
{
throw new Exception("SSIS Package Execution Failed:" + ex.Message.ToString());
}
}
Now I am in a position to Invoke this Package inside Foreach Loop.
static void Main(string[] args)
{
try
{
foreach (DateTime FileDate in SortedDates)
{
ExecuteSSIS_Staging(FileDate);
}
}
Catch(Exception ex)
{
}
}
I am getting Many Issues like
Could not load file or assembly 'Microsoft.SqlServer.ManagedDTS
and few other DLL reference error.
Can anyone suggest me, how can i invoke SSIS Package Inside Foreach loop. The main thing is, In my Local machine it is working obsolutely file. But When i deploy it in server, it is not.
The actuall issue is i have added
Microsoft.SQLServer.ManagedDTS.dll version 9.0
in one machine. When i tried to open it in other machine, some how DLL is refernced to
Microsoft.SQLServer.ManagedDTS.dll version 10.0 version.
I changed it again & executed. Now Working Fine.
I am trying to rename a Hyper-V snapshot (checkpoint) using root\virtualization\v2. None of the standard methods like ModifySystemSettings or ModifyVirtualSystem of Msvm_VirtualSystemSnapshotService or Msvm_VirtualSystemManagementService has been helpful so far.
Powershell Rename-VMSnapshot can do the job however I am not sure it is using WMI.
Any idea?
Here is what worked for me:
//
// Rename last snapshot to desired name
//
using (ManagementBaseObject inParams = vmms.GetMethodParameters("ModifySystemSettings"))
{
ManagementObject setting = null;
ManagementObjectCollection settings = vm.GetRelated(
"Msvm_VirtualSystemSettingData",
"Msvm_MostCurrentSnapshotInBranch",
null,
null,
"Dependent",
"Antecedent",
false,
null
);
foreach (ManagementObject instance in settings)
{
// Usually only one, but loop through to the end to get latest one
if (setting != null)
{
if (string.Compare(
(string)instance["CreationTime"],
(string)setting["CreationTime"],
true) > 0
)
{
// Get latest one since there could be duplicates
setting = instance;
}
}
else
{
setting = instance;
}
}
setting["ElementName"] = snapshotName;
inParams["SystemSettings"] = setting.GetText(TextFormat.WmiDtd20);
using (ManagementBaseObject outParams = vmms.InvokeMethod("ModifySystemSettings", inParams, null))
{
// What this does is get Job managementObject and check JobState to be JobCompleted.
this.ProcessSnapshotMethodResult(outParams, "rename");
}
}
I have activated a WSP file which includes a website template. This works and I can see the solution int he solution gallery. When I try to create a website, based on that template, its not showing up. But it says "Status: Activated".
Then I tried to deactivate it and activate it again manually. Out of a sudden, there is a new template showing up, which takes the name of my template appended by a "2".
So whats happening here exactly? The code to activate my solution is:
System.IO.MemoryStream input = new System.IO.MemoryStream(System.IO.File.ReadAllBytes(rootDirectory + "\\Templates\\Project.wsp"), true);
SPDocumentLibrary solutionGallery = (SPDocumentLibrary)web.Site.GetCatalog(SPListTemplateType.SolutionCatalog);
try
{
SPFile solutionFile = solutionGallery.RootFolder.Files.Add("Project.wsp", input);
SPUserSolution newUserSolution = web.Site.Solutions.Add(solutionFile.Item.ID);
}
catch { ... }
Ok, I found the answer myself and want to share it here. The solution is, not to provide the solution in the catalog, but also to enable the features! It works like this:
System.IO.MemoryStream input = new System.IO.MemoryStream(System.IO.File.ReadAllBytes(rootDirectory + "\\Templates\\Project.wsp"), true);
SPDocumentLibrary solutionGallery = (SPDocumentLibrary)web.Site.GetCatalog(SPListTemplateType.SolutionCatalog);
try
{
SPFile solutionFile = solutionGallery.RootFolder.Files.Add("Project.wsp", input);
SPUserSolution newUserSolution = web.Site.Solutions.Add(solutionFile.Item.ID);
Guid solutionId = newUserSolution.SolutionId;
SPFeatureDefinitionCollection siteFeatures = web.Site.FeatureDefinitions;
var features = from SPFeatureDefinition f
in siteFeatures
where f.SolutionId.Equals(solutionId) && f.Scope == SPFeatureScope.Site
select f;
foreach (SPFeatureDefinition feature in features)
{
try
{
web.Site.Features.Add(feature.Id, false, SPFeatureDefinitionScope.Site);
}
catch { }
}
SPWebTemplateCollection webTemplates = web.Site.RootWeb.GetAvailableWebTemplates(1033);
SPWebTemplate webTemplate = (from SPWebTemplate t
in webTemplates
where t.Title == "Projekt"
select t).FirstOrDefault();
if (webTemplate != null)
{
try
{
web.Site.RootWeb.ApplyWebTemplate(webTemplate.Name);
}
catch { }
}
}

I am creating a program which first checks whether a particular program has been installed or not, if it's installed it continues to execute other code, if it's not installed then it installs the application and then proceeds to execute the other code.
How do i check programatically in VC++ that the application has been installed or not
I got a C# function that does something similar, it looks on both the 32 bit and the 64 bit entries in the registry.I'm assuming you got the right name of the program you are looking for all you need is to match it with key "DisplayName". I doubt you'd have problems making it C++...It would go something like this
string SoftwareKey = #"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall";
bool found = false;
RegistryKey rk = Registry.LocalMachine.OpenSubKey(SoftwareKey);
foreach (string skName in rk.GetSubKeyNames())
{
RegistryKey sk = rk.OpenSubKey(skName);
if (sk.GetValue("DisplayName") != null &&
sk.GetValue("DisplayName").ToString().Equals("WhateverProgramYouAreLookingFor"))
{
//whatever you need to do with it
found = true;
break;
}
}
if(!found)
{
SoftwareKey = #"SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall";
foreach (string skName in rk.GetSubKeyNames())
{
RegistryKey sk = rk.OpenSubKey(skName);
if (sk.GetValue("DisplayName") != null &&
sk.GetValue("DisplayName").ToString().Equals("WhateverProgramYouAreLookingFor"))
{
//whatever you need to do with it
found = true;
break;
}
}
}
I'm making a service that among other has the "photo albums" feature that serve photos to users. User has to be "allowed" to see the photo from the album. So sending the direct link to other person shouldn't allow to view photo.
Photos are stored in the folder outside of the context.
What I need to do is to perform some checks when user requests the photo and then if checks are OK - serve the file. I want to avoid making a wheel and just let tomcat serve the image as it usually does for static files. Can you give some advice on that?
Ok, guys.
After struggling hard with this question I think I've finally found out what to do to solve it. First of all it looks like the question actually decomposes into two independent tasks. One of them is securing access to some resources and second one is feeding resources from the folder outside of the context.
First task is trivial and can be solved by writing a simple filter hanged to "/".
Second task is much less trivial but fortunately also can be resolved. Tomcat uses the implementation of javax.naming.directory.DirContext to load all resources of the given web application including class files. It also allows you to provide the custom implementation of this interface and configure it in the context.xml file. The default implementation is org.apache.naming.resources.FileDirContext. Details here: http://tomcat.apache.org/tomcat-6.0-doc/config/resources.html
I've created my own implementation of DirContext by simply extending FileDirContext. Luckily enough there was a single method that had to be overwritten in order to "hook up" file discovery. The method is called file().
I'm posting my test code here. It is far from perfect and does not take into account the corner cases like renaming files but I don't think that these are needed under a normal run of the server.
The basic idea under this code is to check if the path starts with "virtual directory" prefix and if it is - search for file in the other place in the filesystem (I know there is some duplicate code there but I hope you're not that lazy to remove it if you ever want to use it :-). setVirtualName and setVirtualBase are called automatically to inject the configuration params.

After you have this class in place you have to jar it and put that jar into the Tomcat lib folder. For obvious reasons it cannot go together with war file. In your context.xml you should add a config lines like these:
<?xml version="1.0" encoding="UTF-8"?>
<Context antiResourceLocking="true" antiJARLocking="true">
<Resources
className="com.juriy.tomcat.virtualdir.VirtualFolderDirContext"
virtualName="/upload"
virtualBase="c:/temp/up">
</Resources>
...
...
Now any time user asks for /upload/ it will be resolved to c:\temp. With this technique you can implement loading resources from virtually any location: http, shared folder, database, even version control system. So it is pretty cool.
P.S. I've killed the whole day to make this all work together so don't hesitate to give me your vote if you like the answer :-))
