Delete your old logfiles

In most cases where you have developed a on-premise applikasjon (console, service) these generates logfiles. Either for  debugging purpose, or for validating the day-to-day execution wether there are errors or warning.

I tend to use text files, where I keep them for at least 14 days. The following command will delete all files older than 14 days from the c:\temp\logging folder. I have this at the top of my startup.cmd script.

rem delete files older than 14 days
forfiles /p "C:\temp\Logging" /m "*.*" /c "cmd /c del @path" /D -14

MS CRM list user access via SQL

During my CRM Solution import debugging yesterday, I also wanted to see which user had been logged in to CRM the last few days. After some googling og trying I came up with this SQL statement for listing all users and last time they accessed CRM during the last 3 days.

NB! You have to change the “OrgName” to get this working on you CRM database server. It is tested for CRM 2011 and CRM 2016.

USE MSCRM_Config
SELECT O.FriendlyName, SU.FullName as Name, SUO.LastAccessTime
FROM SystemUserOrganizations SUO
       LEFT JOIN SystemUserAuthentication SUA ON SUO.UserId = SUA.UserId 
                                    AND LEFT(AuthInfo, 1)='C'
       LEFT JOIN Organization O ON SUO.OrganizationId=O.Id
       INNER JOIN OrgName_MSCRM.dbo.SystemUser SU ON SUO.CrmUserId = SU.systemuserid
WHERE LastAccessTime IS NOT NULL 
  AND O.FriendlyName = 'OrgName' 
  AND datediff(DAY,Lastaccesstime, getutcdate()) < 3
ORDER BY lastaccesstime

Enable Dynamics CRM Tracing with powershell

If you have some problems with Dynamics CRM On-premise you are able to enable tracing with PowerShell. In my case, I needed to get debug information on why my solution import is failing when I’m going to move it to a new organization.

Open the powershell prompt and use the Add-PSSnapin command shown in 1). Thereby, You can list the trace setting with the command shown in 2). Before you start the tracing, you show determine the timeline for when the error occurs and just enble it as close as the error as possible. Run the command in 3) to start the tracing. You should stop the tracing immediately after the error has occured. Use command in 4) to stop the tracing.

# 1) add
Add-PSSnapin Microsoft.Crm.PowerShell 

# 2) get crm trace settings
Get-CrmSetting TraceSettings 

# 3) enable tracing
$Setting = Get-CrmSetting TraceSettings
$Setting.Enabled = $True 
$Setting.CallStack=$True
$Setting.Categories="*:Verbose"
$Setting.Directory="C:\temp\crmtrace"
Set-CrmSetting $setting

# 4) disbale tracing
$Setting = Get-CrmSetting TraceSettings
$setting.Enabled = $False
Set-CrmSetting $setting

When you have tons of log file, the trace tool CRM Trace reader is nice to use for searing and filtering.

WPF watermark/hint in TextBox control

After we found out that SOTI Enterprise Mobility Management system didn’t fully support Windows 10 Store Apps in “Kiosk Mode”, we had to rewrite out latest app using WPF technologi instead.

In this process. I wanted a kind of watermark in my TextBox Controls. After some googling, I found a pretty nice library called “Extended WPF Toolkit” on codeplex (and Nuget).

How to create a watermark input textbox

  1. Add “Extended.Wpf.Toolkit” via Nuget
  2. Add XML Namespace at the top of the XAML file
       xmlns:xctk="http://schemas.xceed.com/wpf/xaml/toolkit"
  1. Add “xctk:WatermarkTextBox” instead of “TextBox” Control With the Watermark attribute set to the help text
       <xctk:WatermarkTextBox x:Name="txtSearch" Watermark="type search pattern" />

Happy coding

Year of Silence

Blogging haven’t been my first priority for the last year due different circumstances. As a result, I have decided to set a goal of at least one blog post every month. We have to learn something new every day in this industry to keep up with the changes, so it should always be something to write about 🙂

So, what have I been doing for the last year (2015)?

It started with a competence boom at the KiPi 2015 (“Know It, Prove It”) Challenge at Microsoft Virtual Academy in February where I followed and completed Cloud Development, Mobile Development and Hybrid Cloud learning paths. This inspired me to look at the different Azure exams, but unfortunately, busy projects made it impossible to complete these.

Between March and New Year, I worked on mainly upgrade and migration projects for customers, and the next few blog posts will summarize my experience from these projects and describe what kind of knowledge from these projects I have put into my toolbox.

SQL – find where column is used as foreign key

The T-SQL script  below will find all tables and columns for a particular Primary Key column (located in WHERE clause [pk-table].[pk-column]). This script is pretty useful when you are working close the database, manipulating data directly and so on.

SELECT
    K_Table = FK.TABLE_NAME,
    FK_Column = CU.COLUMN_NAME,
    PK_Table = PK.TABLE_NAME,
    PK_Column = PT.COLUMN_NAME,
    Constraint_Name = C.CONSTRAINT_NAME
FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS C 
	INNER JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS FK 
		ON C.CONSTRAINT_NAME = FK.CONSTRAINT_NAME
	INNER JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS PK 
		ON C.UNIQUE_CONSTRAINT_NAME = PK.CONSTRAINT_NAME
	INNER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE CU 
		ON C.CONSTRAINT_NAME = CU.CONSTRAINT_NAME
	INNER JOIN (
            SELECT
                i1.TABLE_NAME,
                i2.COLUMN_NAME
            FROM
                INFORMATION_SCHEMA.TABLE_CONSTRAINTS i1
            INNER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE i2
                ON i1.CONSTRAINT_NAME = i2.CONSTRAINT_NAME
            WHERE
                i1.CONSTRAINT_TYPE = 'PRIMARY KEY'
           ) PT
    ON PT.TABLE_NAME = PK.TABLE_NAME
WHERE PK.TABLE_NAME = '[pk-table]'
  AND PT.COLUMN_NAME = '[pk-column]'
