• Web UI element to represent two different micro-views of data in the same spot?

  - by Chris McCall

  I've been tasked with laying out a portion of a screen for a customer care (call center) app that serves as sort of a header/summary block at the top of the screen. Here's what it looks like: The important part is in the red box. That little tooltip is the biz's vision for how to represent both the numeric SiteId and the textual Site Name all in the same piece of screen real estate. I asked, and the business thinks the Name is more important than the ID, but lists the Id by default, because the Name can't be truncated in the display, and there's only so much horizontal room to put the data. So they go with the Id, because it's fewer characters, and then they have the user mouse-over the Id to display the name (presumably because the tooltip can be of unlimited width and since it's floating over the rest of the screen, the full name will always be displayed. So, here's my question: Is there some better UI metaphor that I don't know about that could get this job done, while meeting the following constraints?: Does not require the mouse (uses a keyboard shortcut to do the "reveal") Allows the user to copy and paste the name Will not truncate the name Provides for the display of both the ID and name in the same spot Works with IE7

• Why extremely occasionally will one of bof/eof be true for a new non-empty recordset

  - by jjb

  set recordsetname = databasename.openrecordset(SQLString) if recordsetname.bof <> true and recordsetname.eof <> true then 'do something end if 2 questions : the above test can evaluate to false incorrectly but only extremely rarely (I've had one lurking in my code and it failed today, I believe for the first time in 5 years of daily use-that's how I found it). Why very occasionally will one of bof/eof be true for a non-empty recordset. It seems so rare that I wonder why it occurs at all. Is this a foolproof replacement: if recordsetname.bof <> true or recordsetname.eof <> true then Edit to add details of code : Customers have orders, each order begins with a BeginOrder item and end with an EndOrder item and in between are the items in the order. The SQL is: ' ids are autoincrement long integers ' SQLString = "select * from Orders where type = OrderBegin or type = OrderEnd" Dim OrderOpen as Boolean OrderOpen = False Set rs = db.Openrecordset(SQLString) If rs.bof <> True And rs.eof <> True Then myrec.movelast If rs.fields("type").value = BeginOrder Then OrderOpen = True End If End If If OrderOpen F False Then 'code here to add new BeginOrder Item to Orders table ' End If ShowOrderHistory 'displays the customer's Order history ' In this case which looks this this BeginOrder Item a Item b ... Item n EndOrder BeginOrder Item a Item b ... Item n EndOrder BeginOrder Item a item b ... Item m BeginOrder <----should not be there as previous order still open

• Assistance with CC Processing script

  - by JM4

  I am currently implementing a credit card processing script, most as provided by the merchant gateway. The code calls functions within a class and returns a string based on the response. The end php code I am using (details removed of course) with example information is: <?php $gw = new gwapi; $gw->setLogin("username", "password"); $gw->setBilling("John","Smith","Acme, Inc.","888","Suite 200", "Beverly Hills", "CA","77777","US","555-555-5555","555-555-5556","[email protected]", "www.example.com"); // "CA","90210","US","[email protected]"); $gw->setOrder("1234","Big Order",1, 2, "PO1234","65.192.14.10"); $r = $gw->doSale("1.00","4111111111111111","1010"); print $gw->responses['responsetext']; ?> where setlogin allows me to login, setbilling takes the sample consumer information, set order takes the order id and description, dosale takes the amount charged, cc number and exp date. when all the variables are sent validated then sent off for processing, a string is returned in the following format: response=1&responsetext=SUCCESS&authcode=123456&transactionid=23456&avsresponse=M&orderid=&type=sale&response_code=100 where: response = transaction approved or declined response text = textual response authcode = transaction authorization code transactionid = payment gateway tran id avsresponse = avs response code orderid = original order id passed in tran request response_code = numeric mapping of processor response I am trying to solve for the following: How do I take the data which is passed back and display it appropriately on the page - If the transaction failed or AVS code doesnt match my liking or something is wrong, an error is displayed to the consumer; if the transaction processed, they are taken to a completion page and the transaction id is sent in SESSION as output to the consumer If the response_code value matches a table of values, certain actions are taken, i.e. if code =100, take to success page, if code = 300 print specific error on original page to customer, etc.

• Simple Oracle File repository with folder hierarchy

  - by Ope

  I have an application that stores large amount of files (XML and binary) in folder hierarchies. Currently the main method is storing them in file system or using a legacy CMS, which we want to get rid of. The CMS supports Oracle and a customer wants to keep the files in Oracle because of enterprise policies (backup etc.) The question is: Is there a simple implementation of file repository with folder hierarchy for Oracle? What I am looking for is a small .Net component or example code (PL/SQL and/or .Net) that would have the following methods: Create, Delete, Exists Folder CRUD file Move and potentially Copy file or directory Access to files and folders with paths like "/root/folder1/folder2/file.xml" Ability to get all the files and folders in a folder and potentially also the entire directory tree Tree traversal, getting the parent, all children etc. needs to be fast. I need the implementation in .Net, but if it was just the stored procedures, I could create the .Net calling code. I have pointers to generic articles for creating hierarchies in DB, so if I need to do it from scratch, I know where to start. What I am asking here, is there already an implementation that I could take without doing this from scratch? It seems like such a generic requirement... If the answer is a CMS, Document management system or such it should be Open Source or at least quite cheap (some hundreds / server) and it should be possible to deploy it XCopy - hopefully only couple of DLL:s. I do not need - or want - a full featured big CMS with dozens of dlls and especially not an msi-installation. I have tried to google this, but the words "repository", "CMS", "file hierarchy" etc. give so many answers, the searches are pretty much useless. Thanks, OPe

• How to use custom attributes over a web service?

  - by gfeli

  Hi. I am currently trying to add a custom "column name" to a property in a web service. Here is my class. public class OrderCost { public int OrderNum { get; set; } public int OrderLine { get; set; } public int OrderRel { get; set; } public DateTime OrderDate { get; set; } public string PartNum { get; set; } public string Description { get; set; } public decimal Qty { get; set; } public string SalesUM { get; set; } public decimal Cost { get; set; } public decimal Price { get; set; } public decimal Net { get; set; } public decimal Margin { get; set; } public string EntryPerson { get; set; } public string CustID { get; set; } public string Customer { get; set; } } Basically I have another class (on the Silverlight side) that loops through all the properties and creates a column for each property. Thing is, I want to use a different name other than the name of the property. For example, I would like to show "Order Number" instead of OrderNum. I have attempted to use custom attributes but that does not seem to work. Is there way I can provide a different name to these properties over a web service with a use of an attribute? Is there another way I can achieve what I am trying to do?

• Conceptual data modeling: Is RDF the right tool? Other solutions?

  - by paprika

  I'm planning a system that combines various data sources and lets users do simple queries on these. A part of the system needs to act as an abstraction layer that knows all connected data sources: the user shouldn't [need to] know about the underlying data "providers". A data provider could be anything: a relational DBMS, a bug tracking system, ..., a weather station. They are hooked up to the query system through a common API that defines how to "offer" data. The type of queries a certain data provider understands is given by its "offer" (e.g. I know these entities, I can give you aggregates of type X for relationship Y, ...). My concern right now is the unification of the data: the various data providers need to agree on a common vocabulary (e.g. the name of the entity "customer" could vary across different systems). Thus, defining a high level representation of the entities and their relationships is required. So far I have the following requirements: I need to be able to define objects and their properties/attributes. Further, arbitrary relations between these objects need to be represented: a verb that defines the nature of the relation (e.g. "knows"), the multiplicity (e.g. 1:n) and the direction/navigability of the relation. It occurs to me that RDF is a viable option, but is it "the right tool" for this job? What other solutions/frameworks do exist for semantic data modeling that have a machine readable representation and why are they better suited for this task? I'm grateful for every opinion and pointer to helpful resources.

• Unnecessary Redundancy with Tables.

  - by Stacey

  My items are listed as follows; This is just a summary of course. But I'm using a method shown for the "Detail" table to represent a type of 'inheritence', so to speak - since "Item" and "Downloadable" are going to be identical except that each will have a few additional fields relevant only to them. My question is in this design pattern. This sort of thing appears many, many times in our projects - is there a more intelligent way to handle it? I basically need to normalize the tables as much as possible. I'm extremely new to databases and so this is all very confusing to me. There are 5 items. Awards, Items, Purchases, Tokens, and Downloads. They are all very, very similar, except each has a few pieces of data relevant only to itself. I've tried to use a declaration field (like an enumerator 'Type' field) in conjunction with nullable columns, but I was told that is a bad approach. What I have done is take everything similar and place it in a single table, and then each type has its own table that references a column in the 'base' table. The problem occurs with relationships, or junctions. Linking all of these back to a customer. Each type takes around 2 additional tables to properly junction all of the data together- and as such, my database is growing very, very large. Is there a smarter practice for this kind of behavior? Item ID | GUID Name | varchar(64) Product ID | GUID Name | varchar(64) Store | GUID [ FK ] Details | GUID [FK] Downloadable ID | GUID Name | varchar(64) Url | nvarchar(2048) Details | GUID [FK] Details ID | GUID Price | decimal Description | text Peripherals [ JUNCTION ] ID | GUID Detail | GUID [FK] Store ID | GUID Addresses | GUID Addresses ID | GUID Name | nvarchar(64) State | int [FK] ZipCode | int Address | nvarchar(64) State ID | int Name | varchar(32)

• App_Themes Not Loading on Initial Load

  - by Jason Heine

  Hello, I have an application where different users can log in via a single portal login. When they log in, if they belong to more than 1 company they have to select the company they belong to. The theme will change if there is a custom theme for that company. Each page my application has inherits a "CustomPage" class Here is the code for the custom page: public class CustomPage : Page { protected void Page_PreInit(object sender, EventArgs e) { if (Globals.Company != null && Directory.Exists(Page.MapPath("~/App_Themes/" + Globals.Company.CompanyName))) { Page.Theme = Globals.Company.CompanyName; } else { Page.Theme = "Default"; } } } When the customer belongs to more than 1 company, and they select the company they belong to, the theme loads just fine. So, the problem I am having is this: If they belong to just 1 company, the company is automatically selected but the theme does not load right away. However, if I refresh the page, the theme loads just fine. Even the default theme will not load. The page has no css at all until I refresh. I am not using forms authentication and the default theme in the web config is "Default" <pages theme="Default"> Any thoughts to what might be going on? If you need clarification on anything, please ask. Thanks!

• Developing Modular Flex Applications

  - by ukdavo

  Hi there I'd like to be able to understand how to develop a Flex application such that I could provide implementation classes at runtime. In the Java world I'd specify interfaces in an JAR (e.g. myapp-api.jar), the implementation in a separate JAR (e.g. myapp-impl.jar) and package these along with other resources in the application WAR (e.g. myapp.war). Within the code of the application I would instantiate the implementation classes dynamically. Is this approach possible in Flex? I'm aware that I can instantiate classes dynamically so that's a good start. I'm a bit confused by modules, RSLs and SWCs though. I was hoping to create a SWF application that had references to an interfaces SWC and an implementation SWC. The idea is that if I need to tweak the application for a specific customer then I could create a new implementation SWC and not have to modify the SWF or interface SWC. Any ideas?

• Reading/Writing/Modifying a struct in C

  - by user1016401

  I am taking some information from a user (name, address, contact number) and store it in a struct. I then store this in a file which is opened in "r+" mode. I try reading it line by line and see if the entry I am trying to enter already exists, in which case I exit. Otherwise I append this entry at the end of the file. The problem is that when I open the file in "r+" mode, it gives me Segmentation fault! Here is the code: struct cust{ char *frstnam; char *lastnam; char *cntact; char *add; }; Now consider this function. I am passing a struct of information in this function. Its job is to check if this struct already exists else append it to end of file. void check(struct cust c) { struct cust cpy; FILE *f; f=fopen("Customer.txt","r+"); int num=0; if (f!= NULL){ while (!feof(f)) { num++; fread(&cpy,sizeof(struct cust),1,f); if ((cpy.frstnam==c.frstnam)&(cpy.lastnam==c.lastnam)&(cpy.cntact==c.cntact)&(cpy.add==c.add)) { printf("Hi %s %s. Nice to meet you again. You live at %s and your contact number is %s\n", cpy.frstnam,cpy.lastnam,cpy.add,cpy.cntact); return; } } fwrite(&c,sizeof(struct cust),1,f); fclose (f); } printf("number of lines read is %d\n",num); }

• Eclipc java,writting a program [closed]

  - by ghassar

  I have an important exercise for that i found in the internet please i need help in using eclipc java thanks i have to design, implement, test and document a Java program (a set of classes) for one of the following problem specifications: Problem 1 – Jubilee Estate Agency Property Management System A local Estate Agent would like a prototype system to keep track of properties that are offered for sale. The Estate Agent sells domestic and commercial properties. You will need to define classes that represent the Estate Agency System. You should design your system and the classes that you will need before starting coding. Your system must have a graphical user interface and be designed and developed using the object-oriented principles of the MVC architecture design pattern i.e. the user interface class must be separate from the other classes. The initial basic requirements for the system are as follows: • Include a list of domestic properties for sale that include details of: address, description, selling price, and number of rooms • Include a list of commercial properties for sale that include details of: address, description, selling price, and area in square metres • Enable the properties that are for sale to be viewed on the screen • Allow the customer to select one or more properties to be placed on a ‘viewing list’ so that the properties can be visited in person • Display on the screen the viewing list that shows the details of the properties chosen • Provide a basic search facility to find properties that are for sale in a particular price band and display the results • Enable a property to be marked as sold

• Set tier price on different products (special conditions) in Magento?

  - by user1547625

  Let’s say I sell mobile phones. I might sell phones with the following tiered pricing iPhone4 (1x$200ea. 3x$150ea. 10x$100ea.) iPhone4s (1x$300ea. 3x$250ea. 10x$200ea.) iPhone5 (1x$500ea. 3x$400ea. 10x$1300ea.) Plus maybe I sell Samsungs, Nokias, accessories, etc. So let’s say a customer wants to buy 3 iphones, but they want 1x iPhone 4, 1x iPhone 4s and 1x iPhone 5. Instead of getting the single unit price for each, we would want to group iphones, so that they would get the 3x price for each unit. So they would spend $150 on the iPhone 4, $250 on the iPhone 4s and $400 on the iPhone 5.... We’d have several categories and could create some type of spreadsheet for you, but would want to also have the ability to set up this categorization in the future. So please tell me how to get this done from magento admin or any other way?

• HOWTO: Disable complex password policy on Hyper-V Server 2008?

  - by Ian Boyd

  How do you disable the password complexity requirements on a Microsoft Hyper-V Server 2008 R2? Keep in mind that when you log into the server, the only UI you have is: And you cannot run gpedit.msc: C:\Users\Administrator>gpedit.msc 'gpedit.msc' is not recognized as an internal or external command, operable program or batch file. because there are no .msc snap-ins installed with Microsoft Hyper-V Server 2008 R2. The problem comes when you're trying to add an account to the server, so you can manage it, but it doesn't like most passwords: And, predictably, typing NET HELPMSG 2245 gives you The password does not meet the password policy requirements. Check the minimum p assword length, password complexity and password history requirements. i hoped it would have been a friendly user experience, and either: offered to disable the password policy tell me how to disable the password policy tell me how to check the minimum password length, password complexity and password history requirements. Password Complexity Requirements The Microsoft's default password complexity for Server Core is: Passwords cannot contain the user’s account name or parts of the user’s full name that exceed two consecutive characters. Passwords must be at least six characters in length. Passwords must contain characters from three of the following four categories: 1.English uppercase characters (A through Z). 2.English lowercase characters (a through z). 3.Base 10 digits (0 through 9). 4.Non-alphabetic characters (for example, !, $, #, %). External links Technet Forums: Hyper-V Server disable complex passwords Technet: Passwords must meet complexity requirements of the installed password filter Update: 2k views? So many people keep coming coming to it: up-vote it!

• SQL Server 2008 Restore from Backup fails with error 3241 'cannot process this media family'

  - by pearcewg

  I am attempting to backup a database from a SQL Server instance on one machine and restore it to another, and I am encountering the frequently discovered 'SQL Server cannot process this media family' error. Each of my instances are SQL Server 2008, but with different patch levels Restore: 10.0.2531.0 Backup: 10.0.1600.22 ((SQL_PreRelease).080709-1414 ) The restore DB is express. Not sure about the backup version. The backup version is on a virtual private server. The restore is on my development box. When I restore to a different database on the source (backup) server, it restores fine. Lots of stuff on google about this issue, some on stackoverflow about this issue, but nothing which is this exact situation. Any thoughts? It should be straightforward to do a backup and restore from one machine to another (having done this thousands of times in with SQL 6.5,7,2000,2005). Any ideas how to restore a database in this situation, which gives this error when attempting to restore? PARTIAL RESOLUTION: When I restored to a different box, running SQL 2008 Express on Windows Server 2003, all worked well. It just wouldn't work on the Windows 7 box. Not sure why. If anyone else has a similar experience, please let me know (there are many similar issues in different forums out there).

• Managing scalability and availability with two servers running Apache Httpd, Apache Mina and MySQL

  - by celalo

  Hello, I am not a developer and I don't much experience with scalable server architectures. But I am in need of a highly available and scalable system for one of my projects. There is going to be two servers I am going to use for the time being. Both with 4 core CPUs and 8 GB RAM with RAID structures running CentOS 5.4. I will also have feature called "Failover IP" which enables to direct an IP address to another server within short time. The applications which will be run on the servers: There is going to be a Java application based on Apache Mina server for handling TCP requests from some hundreds of network devices where the devices are going to send request as much as one request per minute. Handling those requests, includes parsing the requests and inserting a few rows to the Database. Parsing requests before inserting data to the DB does take neglectable time. There is going to be MySQL server, as I stated above. Also there is going to be a PHP web application running on Apache Httpd Server which uses the same DB with the Java application. What I wish to have is to make use of those two servers at the most. I was imagining to have the servers identical, sharing the work load. MySQL could be a cluster maybe? And if some application fails or the whole machine goes down, the other will continue serving the requests seamlessly. Reminding that a "Failover IP" feature will be available for me to take advantage of. Also, It should be kept in mind that number of servers could increase in time, to meet the demand. What can you suggest? Which kind of tools I can make use of? Which kind of monitoring software (paid/unpaid) I have? Thanks in advance.

• Extract Key and Certificate from Kemp Loadmaster?

  - by Matt Simmons

  I'm trying very hard to get away from a set of Kemp Loadmasters that I bought years ago to provide HA access to our website. Part of that process is going to be putting the key and certificate in the new solution (HAproxy with nginx doing SSL). Unfortunately, I've come up against a problem... The Kemp has built-in certificate management, and it generates CSR's at the touch of a button. It also supported importing of signed certificates, however it does not, so far as I can tell, allow any kind of export of the key itself. There is a "backup key and certificates" ability, however here's the text from the manual: LoadMaster supports exporting of ALL certificate information. This includes private key, host and intermediate certificates. The export file is designed to be used for import into another LoadMaster and is encrypted. Export and import can be completed using the WUI at Certificates -> Backup/Restore Certs. Please make sure to note the pass phrase used to create the export, it will be required to complete the import. You can selectively resort only Virtual Service certificates including private keys, intermediate certificates or both. Well, that is great, but as for actually DEALING with the certs, I'm apparently out of luck. Of course, I'm not going to give up that easily. I ran "file" on the saved cert bundle and got this: $ file client1.certs.backup client1.certs.backup: gzip compressed data, from Unix Well, awesome, I thought. Maybe it's just a .tar.gz, so I unzipped it, and that went fine, but my attempts to untar it didn't work, and running "file" on it now just gives this: $ file client1.certs.backup client1.certs.backup: data So that's where I'm stuck. Anyone have experience with these?

• apache Client Certificate Authentication errors: Certificate Verification: Error (18): self signed certificate

  - by decoy

  So I have been following instructions on setting up Client Certificate Authentication in Apache2 w/ mod_ssl. This is solely for the purpose of testing an application against CAA, not for any sort of production use. So far I've followed http://www.impetus.us/~rjmooney/projects/misc/clientcertauth.html for advice on generating my CA, server, and client encryption information. I've put all three of them into /etc/ssl/ca/private. I've setup the following additional directives in my default_ssl site file: <IfModule mod_ssl.c> <VirtualHost _default_:443> ... SSLEngine on SSLCertificateFile /etc/ssl/ca/private/server.crt SSLCertificateKeyFile /etc/ssl/ca/private/server.key SSLVerifyClient require SSLVerifyDepth 2 SSLCACertificatePath /etc/ssl/ca/private SSLCACertificateFile /etc/ssl/ca/private/ca.crt <Location /> SSLRequireSSL SSLVerifyClient require SSLVerifyDepth 2 </Location> <FilesMatch "\.(cgi|shtml|phtml|php)$"> SSLOptions +StdEnvVars </FilesMatch> <Directory /usr/lib/cgi-bin> SSLOptions +StdEnvVars </Directory> ... </VirtualHost> </IfModule> I've install the p12 file into Chrome, but when I go to visit https://localhost, I get the following errors Chrome: Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error. Apache: Certificate Verification: Error (18): self signed certificate If I had to guess, one of my directives is not setup right to load and verify the p12 w/ my self created CA. But I can't for the life of me figure out what it is. Would anyone have more experience here who could point me in the right direction?

• Fix ACPI DSDT of Amilo Pa 1538

  - by kayahr

  I have a Fujitsu-Siemens Amilo Pa 1538 laptops and installed Ubuntu 10.04 on it (Kernel 2.6.32). Main problem is that the fans of the notebook are always on even when the temperature is low. Another problem is that the display brightness can not be adjusted. Since some years I use Dell laptops and never experienced any ACPI problems so I thought that it is no longer needed to fix ACPI tables but now I have this crap of a laptop and I think I have to do it. Unfortunately I need some help repairing the DSDT. The dsdt.dat and dsdt.dsl of the laptop can be found here: http://www.ailis.de/~k/permdata/20100420/dsdt/ Compiling the DSDT gives the following output: # iasl -sa dsdt.dsl Intel ACPI Component Architecture ASL Optimizing Compiler version 20090521 [Jun 30 2009] Copyright (C) 2000 - 2009 Intel Corporation Supports ACPI Specification Revision 3.0a dsdt.dsl 81: Method (\_WAK, 1, NotSerialized) Warning 1080 - ^ Reserved method must return a value (_WAK) dsdt.dsl 207: Method (_L10, 0, NotSerialized) Warning 1087 - ^ Not all control paths return a value (_L10) dsdt.dsl 2861: Method (NVIF, 3, NotSerialized) Warning 1087 - ^ Not all control paths return a value (NVIF) dsdt.dsl 4551: Store (\_SB.PCI0.LPC0.PMRD (0xFA), Local0) Warning 1099 - Statement is unreachable ^ ASL Input: dsdt.dsl - 4962 lines, 162828 bytes, 2300 keywords AML Output: dsdt.aml - 17627 bytes, 591 named objects, 1709 executable opcodes Compilation complete. 0 Errors, 4 Warnings, 0 Remarks, 519 Optimizations Anyone here with DSDT experience who can help me fixing the DSDT?

• Could not continue scan with NOLOCK due to data movement during installation

  - by dbdev1

  I am running Windows Server 2008 Standard Edition R2 x64 and I installed SQL Server 2008 Developer Edition. All of the preliminary checks run fine (Apart from a warning about Windows Firewall and opening ports which is unrelated to this and shouldn't be an issue - I can open those ports). Half way through the actual installation, I get a popup with this error: Could not continue scan with NOLOCK due to data movement. The installation still runs to completion when I press ok. However, at the end, it states that the following services "failed": database engine services sql server replication full-text search reporting services How do I know if this actually means that anything from my installation (which is on a clean Windows Server setup - nothing else on there, no previous SQL Servers, no upgrades, etc) is missing? I know from my programming experience that locks are for concurrency control and the Microsoft help on this issue points to changing my query's lock/transactions in a certain way to fix the issue. But I am not touching any queries? Also, now that I have installed the app, when I login, I keep getting this message: TITLE: Connect to Server ------------------------------ Cannot connect to MSSQLSERVER. ------------------------------ ADDITIONAL INFORMATION: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 67) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=67&LinkId=20476 ------------------------------ BUTTONS: OK ------------------------------ I went into the Configuration Manager and enabled named pipes and restarted the service (this is something I have done before as this message is common and not serious). I have disabled Windows Firewall temporarily. I have checked the instance name against the error logs. Please advise on both of these errors. I think these two errors are related. Thanks
